6 Transmitters for mounting in sensor head SITRANS TH100 two-wire system (Pt100) Overview Application Used in conjunction with Pt100 resistance thermometers, the SITRANS TH100 transmitters are ideal for measuring temperatures in all industries. Due to its compact size it can be installed in the connection head type B (DIN 4729) or larger. The output signal is a direct current from 4 to 20 ma that is proportional to the temperature. Parameterization is implemented over the PC using the parameterization software SIPROM T and the modem for SITRANS TH100/TH200. If you already have a "modem for SITRANS TK" (Order No. 7NG190-6KB), you can continue using this to parameterize the SITRANS TH100. Transmitters of the "intrinsically-safe" type of protection can be installed within potentially explosive atmospheres. The devices comply with the Directive 94/9/EC (ATEX), as well as FM and CSA regulations. The SITRANS TH100 dispenses with electrical isolation and universal sensor connection to provide a low-cost alternative for Pt100 measurements. For the parameterization, the SIPROM T software is used in combination with the modem for SITRANS TH100/TH200. Its extremely compact design makes the SITRANS TH100 ideal for the retrofitting of measuring points or for the use of analog transmitters. The transmitter is available as a non-ex version as well as for use in potentially explosive atmospheres. Benefits Two-wire transmitter Assembly in connection head type B (DIN 4729) or larger, or on a standard DIN rail Can be programmed, which means that the sensor connection, measuring range, etc. can also be programmed Intrinsically-safe version for use in potentially explosive areas Function Mode of operation The measured signal supplied by a Pt100 resistance thermometer (2, or 4-wire system) is amplified in the input stage. The voltage, which is proportional to the input variable, is then converted into digital signals by a multiplexer in an analog/digital converter. They are converted in the microcontroller in accordance with the sensor characteristics and further parameters (measuring range, damping, ambient temperature etc.). The signal prepared in this way is converted in a digital/analog converter into a load-independent direct current of 4 to 20 ma. An EMC filter protects the input and output circuits against electromagnetic interferences. Input Output Microcontroller SITRANS TH100, function diagram /6 Siemens FI

Due to their compact size they can be installed in the connection head type B (DIN 4729) or larger. The following sensors/signal sources can be connected over their universal input module: Resistance thermometers (two, three or four-wire system) Thermocouple elements Resistance-based sensors and DC voltage sources The output signal is a direct current from 4 to 20 ma in accordance with the sensor characteristic. Transmitters of the "Intrinsically-safe" type of protection can be installed within potentially explosive atmospheres (zone 0). Type of protection Ex n (zone 2) can also be achieved. Explosionproof versions for Europe, USA and Canada are also available. Function The SITRANS TH200 is configured over a PC. A USB or RS 22 modem is linked to the output terminals for this purpose. The configuration data can now be edited using the SIPROM T software tool. The configuration data are then permanently stored in the non-volatile memory (EEPROM). Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case of a sensor short-circuit, the LED flashes red, an internal device fault is indicated by a steady red light. The test socket can be used to connect an ammeter at any time for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop. µ µ Input Output SITRANS TH200 function diagram Siemens FI /9

26 Transmitters for rail mounting SITRANS TR200 two-wire system, universal Overview Application SITRANS TR200 transmitters can be used in all industrial sectors. Their compact design enables simple mounting on standard DIN rails on-site in protective boxes or in control cabinets. The following sensors/signal sources can be connected over their universal input module: Resistance thermometers (two, three or four-wire system) Thermocouple elements Resistance-based sensors and DC voltage sources The output signal is a direct current from 4 to 20 ma in accordance with the sensor characteristic. Transmitters of the "Intrinsically-safe" or Ex nal (zone 2) type of protection can be installed within potentially explosive atmospheres. Ultra flexible - with the universal SITRANS TR200 transmitter Two-wire devices for 4 to 20 ma Enclosure for rail mounting Universal input for virtually any type of temperature sensor Configurable over PC Benefits Compact design Electrically isolated Test sockets for multimeters Diagnostics LED (green/red) Sensor monitoring open circuits and short-circuits Self-monitoring Configuration status stored in EEPROM Expanded diagnostic functions, such as slave pointer, operating hours counter, etc. Special characteristic Electromagnetic compatibility to EN 6126 and NE21 Function The SITRANS TR200 is configured over a PC. A USB or RS 22 modem is linked to the output terminals for this purpose. The configuration data can now be edited using the SIPROM T software tool. The configuration data are then permanently stored in the non-volatile memory (EEPROM). Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case of a sensor short-circuit, the LED flashes red, an internal device fault is indicated by a steady red light. The test socket can be used to connect an ammeter at any time for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop µ 4 µ 5 6 SITRANS TR200 function diagram /26 Siemens FI

32 Transmitters for rail mounting SITRANS TR00 two-wire system, universal, HART Overview Siemens AG 2007 Special characteristic Electromagnetic compatibility to EN 6126 and NE21 "HART" to beat - the universal SITRANS TR00 transmitter Two-wire devices for 4 to 20 ma, HART Device for rail mounting Universal input for virtually any type of temperature sensor Configurable over HART Benefits Compact design Electrically isolated Test sockets for multimeters Diagnostics LED (green/red) Sensor monitoring open circuits and short-circuits Self-monitoring Configuration status stored in EEPROM Expanded diagnostic functions, such as slave pointer, operating hours counter etc. Application SITRANS TR00 transmitters can be used in all industrial sectors. Their compact design enables simple mounting on standard DIN rails on-site in protective boxes or in control cabinets. The following sensors/signal sources can be connected over their universal input module: Resistance thermometers (two, three or four-wire system) Thermocouple elements Resistance-based sensors and DC voltage sources The output signal is a direct current from 4 to 20 ma in accordance with the sensor characteristic, superimposed by the digital HART signal. Transmitters of the "Intrinsically-safe" or Ex nal (zone 2) type of protection can be installed within potentially explosive atmospheres. Function The SITRANS TR00 is configured over HART. This can be done using a handheld communicator or even more conveniently with a HART modem and the SIMATIC PDM parameterization software. The configuration data are then permanently stored in the non-volatile memory (EEPROM). Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case of a sensor short-circuit, the LED flashes red, an internal device fault is indicated by a steady red light. The test socket can be used to connect an ammeter at any time for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop µ 4 µ 5 6 SITRANS TR00 function diagram /2 Siemens FI

With numerous new functions it sets new standards for temperature transmitters. With its diagnostics and simulation functions the SITRANS TW provides the necessary insight during commissioning and operation. And using its HART interface the SITRANS TW can be conveniently adapted with SIMATIC PDM to every measurement task. All SITRANS TW control room devices are available in a non-intrinsically safe version as well as in an intrinsically safe version for use with the most stringent requirements. Application The SITRANS TW transmitter is a four-wire rail-mounted device with a universal input circuit for connection to the following sensors and signal sources: Resistance thermometers Thermocouple elements Resistance-based sensors/potentiometers mv sensors As special version: - V sources - Current sources The 4-wire rail-mounted SITRANS TW transmitter wire is designed for control room installation. It must not be mounted in potentially explosive atmospheres. All SITRANS TW control room devices are available in a non-intrinsically safe version as well as in an intrinsically safe version for use with the most stringent requirements. Function Features Transmitter in four-wire system with HART interface Housing can be mounted on 5 mm rail or 2 mm G rail Screw plug connector All circuits electrically isolated Output signal: 0/4 to 20 ma or 0/2 to 10 V Power supplies: 115/20 V AC/DC or 24 V AC/DC Explosion protection [EEx ia] or [EEx ib] for measurements with sensors in the hazardous area Temperature-linear characteristic for all temperature sensors A 8 D µc EEPROM The signal output by a resistance-based sensor (two-wire, threewire, four-wire system), voltage source, current source or thermocouple is converted by the analog-to-digital converter (1, function diagram) into a digital signal. This is evaluated in the microcontroller (2), corrected according to the sensor characteristic, and converted by the digital-to-analog converter (6) into an output current (0/4 to 20 ma) or output voltage (0/2 to 10 V). The sensor characteristics as well as the electronics data and the data for the transmitter parameters are stored in the non-volatile memory (). AC or DC voltages can be used as the power supply (1). Any terminal connections are possible for the power supply as a result of the bridge rectifier in the power supply unit. The PE conductor is required for safety reasons. A HART modem or a HART communicator permit parameterization of the transmitter using a protocol according to the HART specification. The transmitter can be directly parameterized at the point of measurement via the HART output terminals (10). The operation indicator (4) identifies a fault-free or faulty operating state of the transmitter. The limit monitor (9) enables the signaling of sensor faults and/or limit violations. In the case of a current output, the current can be checked on a meter connected to test socket (12). Diagnosis and simulation functions 5 7 D Power supply unit A The SITRANS TW comes with extensive diagnosis and simulation functions. Physical values can be defined with the simulation function. It is thus possible to check the complete signal path from the sensor input to inside the control system without additional equipment.

50 Transmitter for field mounting with temperature sensor SITRANS TF2 Digital display thermometer Overview The temperature transmitter SITRANS TF2 integrates three elements in one device: a Pt100 resistance thermometer in a stainless steel protective tube, a stainless steel housing with a high degree of protection, and a built-in transmitter with LCD and three keys for parameterization. It is used to indicate and monitor the temperature measured at the point of installation. The SITRANS TF2 is available in an axial and a radial version. Benefits Robust stainless steel housing with two connection versions High measuring accuracy Precise display with a resolution of 1 / 100 C in the highest measuring range Measuring ranges from -50 to +200 C ( F) parameterizable Customer-specific lengths and materials possible for the protective tube Stainless steel protective tube with high resistance to chemicals Signaling of limit violation in the LCD as well as with a red LED Application The SITRANS TF2 is used for indicating and monitoring a temperature variable at the point of installation. Applications are all process engineering branches, e.g.: Chemical industry Energy industry Long-distance heating Water supply Sewage works Food industry Steelworks and the cement industry Pharmaceutical industry Biotechnology Design The SITRANS TF2 has a stainless steel housing (diam. 80 mm) with protective glass. The stainless steel protective tube with screw socket contains the temperature sensor Pt100. By using stainless steel for the protective tube it displays high chemical resistance, which means that the temperature sensor is well protected against external effects The protective tube is supplied as standard in lengths of 170 mm or 260 mm; a customer-specific version is also possible. Similarly, the protective tube can be supplied in the material of the customer s choice. At the rear of the housing is the electrical connection for the voltage supply using a current loop of 4 to 20 ma. The connection is made with plug connectors to EN A. At the front of the housing is the 5-digit display behind a glass cover. Underneath the display are the keys for parameterizing the SITRANS TF2. Above the display are a green and a red LED for indicating the operating status. The SITRANS TF2 is available in two versions (see "Dimensional drawings ): In the radial version (type A) the display is fitted in parallel with the protective tube. The display can be rotated by up to ±120 relative to the protective tube. In the axial version (type B) the display is at right angles to the protective tube. The display can be rotated by 60 relative to the protective tube.

A temperature-related voltage drop is thus created over the sensor. The voltage drop is converted on the analog/digital converter (A/D) into a digital signal. In the microcontroller (µc) the digital signal is linearized and evaluated in accordance with the data saved in the EEPROM. The processed data are shown in the display. In addition the values are converted on the digital/analog converter (D/A) and the voltage/current transformer (U/I) into a temperature-linear current signal I A (4 to 20 ma).

51 Transmitter for field mounting with temperature sensor SITRANS TF2 Digital display thermometer Display Display The SITRANS TF2 has a 5-digit display behind a glass cover. The following data are shown on the display: measured temperature unit ( C, F, R or K and ma or %) limit violation, indicated by LED and arrow symbols in the display Settings The SITRANS TF2 is set using the input keys behind the glass cover underneath the display. The key "M" is used to selected the operating mode. Following modes of operation are available: Measured value Password Unit of measurement Start of scale and end Upper and lower limit value Offset Output current calibration Upper and lower current saturation limit Electrical damping The other two keys are used to set the values in the individual operating modes. Monitoring Two LED indicators are fitted above the display to monitor the set range and the status: The green LED signals that the measured temperature lies within the set limits. The red LED lights up when the measured temperature lies outside the set limits and when there is an error.

53 Transmitter for field mounting / field indicator SITRANS TF - Transmitter, two-wire system and SITRANS TF - Field indicator for 4 to 20 ma Overview Our field devices for heavy industrial use HART, Universal 4 to 20 ma, universal Field indicator for 4 to 20 ma signals The temperature transmitter SITRANS TF works where others feel uncomfortable. Benefits Universal use - as transmitter for resistance thermometer, thermoelement, Ω or mv signal - as field indicator for any 4 to 20 ma signals Local sensing of measured values over digital display Rugged two-chamber enclosure in die-cast aluminium or stainless steel Type of protection IP68 Test terminals for direct read-out of the output signal without breaking the current loop Can be mounted elsewhere if the measuring point - is not easily accessible - is subject to high temperatures - is subject to vibrations from the system - or if you want to avoid long neck tubes and/or protective tubes Can be mounted directly on American-design sensors Wide range of approvals for use in potentially explosive atmospheres. "Intrinsically safe, non-sparking and flameproof" type of protection, for Europe and USA. Function Configuration The communication capability over the HART protocol V 5.9 of the SITRANS TF with an integrated SITRANS TH00 permits parameterization using a PC or HART communicator (hand-held communicator). The SIMATIC PDM makes it easy. Parameterization is carried out using a PC for SITRANS TF - with the integrated and programmable SITRANS TH200. Available for this purpose are a special modem and the software tool SIPROM T. Mode of operation Mode of operation of SITRANS TF as temperature transmitter The sensor signal, whether resistance thermometer, thermocouple or Ω and/or V signal, is amplified and linearized. Sensor and output side are electrically isolated. An internal cold junction is integrated for measurements with thermocouples. The device outputs a temperature-linear direct current of 4 to 20 ma. As well as the analog transmission of measured values from 4 to 20 ma, the HART model also supports digital communication for online diagnostics, measured value transmission and configuration. SITRANS TF automatically detects when a sensor should should be interrupted or is indicating a short-circuit. The practical test terminals allow direct measurement of 4 to 20 ma signals over an ammeter without interrupting the output current loop. Mode of operation of SITRANS TF as field indicator Any 4 to 20 ma signal can be applied to the generous terminal block. As well as a range of predefined measurement units, the adjustable indicator also supports the input of customized units. This means that any 4 to 20 ma signal can be represented as any type of unit, e.g. pressure, flow rate, filling level or temperature.

60 Resistance thermometers Technical description Siemens AG 2007 Design A resistance thermometer comprises the measuring resistor (metal; platinum, Pt or nickel, Ni) and the mounting and connection parts required in each case. In the standard version, the measuring resistors are embedded in ceramic. In the case of special vibration resistance requirements, the Pt measuring resistors are double-wound and fused into glass. Measuring resistors of class B are supplied. A range of resistors of class A or 1/ to 1/10 class B is available on request. Single and double resistance thermometers are available. Components and circuitry of a resistance thermometer To protect the measuring resistor for industrial measurements and to enable easy replacement, it is fixed in a measuring insert (4) which in turn is fitted in a protective tube (5). The measuring insert is spring-mounted in the connection head (1) of the protective tube using two screws. The internal conductor (10) in the measuring insert connects the measuring resistor (11) to the terminals on the terminal block. Depending on the measuring range and the accuracy required, the thermometers are connected in two-wire, three-wire or fourwire systems to the output devices. The measuring inserts are therefore available with two, three or four internal conductors. If the resistance of the internal conductor is negligibly small, measuring inserts with only two internal conductors can be used for the three-wire and four-wire systems. Exact balancing of the internal conductor under operating conditions is only possible with three conductors. If the resistance of the internal conductor is greater than 0.2 Ω, its magnitude is indicated on the mounting flange of the measuring insert. Function Measuring resistor Measuring resistors The measuring resistor changes with the temperature in accordance with a certain reproducible series of calibration data (see the table "Calibration data for platinum measuring resistors (to DIN EN 60751) under "Technical data ). The changes in resistance are transmitted as changes in voltage to indicators, recorders or controllers directly via copper wires or via transmitters. The type of measuring circuit depends on the instrument to be connected and the required measuring range. The measuring resistors are balanced at 0 C (2 F) to 100 Ω ± 0.12 Ω. The calibration values of the resistors (i.e. the dependence of the resistor on the temperature) and the permissible deviations are specified in DIN EN (IEC 751) (see the table "Error limits according to DIN EN under "Technical Specifications ). Measuring resistors of class B are supplied. A range of resistors of class A or 1/ to 1/10 class B is available on request. Measuring principle of the resistance temperature measurement The thermometer is heated up by the thermometer current compared to the material to be measured. The heating-up error thus produced increases with the square of the thermometer current and linearly with the resistance of the measuring resistor. Apart from the magnitude of the thermometer current, the error depends on the design of the thermometer and on the heat transfer between the protective tube and the medium. A high measuring power is required for output instruments operating according to the deflection method. To keep the heating-up error within permissible limits, the thermometer current should not be greater than 10 ma in this case. When measuring the temperature of gases with very small flow velocities, a considerably greater heating-up error occurs than in measurements with very fast gases or liquids. The heating-up error is negligibly small with high flow velocities. Protection fitting/protective tubes Measuring resistors are suitable for temperatures from Made of platinum C ( F) Made of nickel C ( F), briefly up to 180 C (56 F) Suitable protective fittings are used for installation in pipelines, tanks etc. depending on the mechanical or chemical requirements. The materials for the protective tubes or combinations of different protective tube materials must be carefully selected in order to meet the requirements due to static pressure, flow and temperature Furthermore, the indication response should be as fast as possible. Installation examples with the suitable protective tube materials can be found under "Technical data" in the table "Installation examples and material of protective tubes". The type of installation of the protective tubes depends on the application. The protective tubes are screwed into the pipelines in the case of operating pressures up to approx. 90 bar. Tapered protective tubes which can be welded in are available for higher pressures. Thermometers for measuring furnace temperatures are fixed using flanges. Owing to the different operating conditions, no guarantee can be given for protective fittings. The manufacturer is responsible for damages and measuring errors caused by wrong installation in compliance with the General Terms of Delivery if the instruments have been installed by the manufacturer and if the specifications for the operating conditions furnished by the customer were correct and sufficiently detailed. /60 Siemens FI

74 Resistance thermometers Accessories Measuring inserts, not explosion protected Design Components (design to DIN 4762) Measuring insert with resistor, insert tube with retaining plate, terminal block with clamping springs and 2 or internal conductors of Cu-Ni sheathed wire for each Pt100 measuring resistor. The resistance of the internal conductors is stated on the measuring insert if it is greater than 0.2 Ω. The measuring inserts have a filling of Al 2 O powder which surrounds the measuring resistor and the internal conductors and results in a high vibration resistance (for temperatures up to 600 C (1112 F). The winding is embedded in a ceramic body.

79 Thermocouples Technical description Design A thermocouple comprises The thermocouple element (sensor) and The mounting and connection parts required in each case. The thermocouple element is formed by two conductors of dissimilar metals or metal alloys which are soldered or welded together at one end, the measuring junction: Thermocouple element Function Measuring principle of the thermocouple element If the measuring junction is exposed to a temperature different from that at the free ends of the thermocouple, a voltage (the thermoelectric voltage, Seebeck effect) is produced at these free ends. The magnitude of the thermoelectric voltage depends on the difference in temperature between the measuring junction and the free ends, and on the combination of materials in the thermocouple. Since a thermocouple always measures a temperature difference, the free ends of the thermocouple must be connected to a reference junction (cold conjunction) and held constant at a known temperature. Calibration data for thermoelectric voltages and permissible deviations The calibration data and the permissible deviations for commonly used thermocouples are defined isee Technical Data, Table "Calibration data for thermoelectric voltages and error limits"). The thermocouples Cu-CuNi and Fe-CuNi to DIN 4710 are used for replacement purposes. Thermocouples of class 2 are supplied as standard. For more accurate measurements, thermocouples are available with half the DIN tolerance or with a test certificate. The tolerances only apply to the condition upon delivery. During operation at high temperatures, the tolerances of the thermocouples may change due to absorption of foreign matter, oxidation or evaporation of alloy components. Mode of operation The thermocouples are extended from the connection point to a point whose temperature is as constant as possible (the cold junction) by means of extension leads. The extension leads have the same color code as the associated thermocouple elements; the positive pole is marked in red. Correct polarity must be ensured since otherwise large errors will occur. Up to 200 C, the same calibration data and tolerances apply to the extension leads as to the corresponding thermocouples. The influence of temperature changes at the cold junction can be balanced by means of a compensating circuit, e.g. a compensating box. The reference temperature is 0 (2 F ) or 20 C (68 F). It is also possible to keep the cold junctions at a constant temperature of 50, 60 or 70 C (122, 140 or 158 F) using a thermostat (for several measuring junctions). The connections from the cold junction to the measuring or process instrument are made using copper leads. With energy-consuming instruments such as indicators or multipoint recorders, the complete measuring circuit (thermocouple, extension lead and copper lead) must be balanced in the operating condition using a resistor. SITRANS T transmitters and KOMPENSOGRAPH servo recorders for connection to thermocouple elements have a built-in compensating circuit for balancing the effect of the ambient temperature on the cold junction. Lead balancing is not necessary in this case because of the high input impedance. Protection fitting/protective tubes The thermocouple can be protected against mechanical stress and chemical attack by a ceramic or metal protective tube which may be mounted using flanges, screwed glands or by welding into the pipeline or tank. The thermocouple element terminates in the connection head. Installation examples with specification of the recommended thermocouples and protective tube materials are listed on pages "Technical Data"and "Installation Examples". Owing to the different operating conditions, no guarantee can be given for protective fittings. The manufacturer is responsible for damages and measuring errors caused by wrong installation in compliance with the General Terms of Delivery if the instruments have been installed by the manufacturer and if the specifications for the operating conditions furnished by the customer were correct and sufficiently detailed. Thermocouple elements are very compatible since it is almost always possible to adapt them in shape and size to the particular problem. The temperature-responsive part is almost pointshaped. Thermocouple elements are therefore particularly suitable for measuring rapidly changing temperatures. Siemens FI /79

93 Thermocouples Accessories - Cold junction thermostat for 6 or 12 measuring points Overview The cold junction thermostat is used to keep the cold junction temperature constant when measuring temperature using thermocouples. Design The cold junction thermostat consists of an aluminium block in which 6 or 12 reference elements are fitted, a controller, a heater and a power supply unit. The aluminium block, controller, heater and power supply unit are arranged in two blocks potted in synthetic resin. In this manner, uniform temperature distribution and protection against external effects are ensured. The cast blocks are fitted to the base plate using metal brackets, thus ensuring high resistance to vibration. The device has a red lamp visible on the outside of the door to permit checking of the temperature in the aluminium block (thermostat). It is also possible to fit a Pt100 resistance thermometer or an electronic monitoring unit with relay output whose NC contact opens if there is a fault. The cold junction thermostat has a sheet-steel housing.

99 Overview Siemens AG 2007 Resistance thermometers for food, pharmaceuticals and biotechnology Resistance thermometers with clamp-on system Response time / accuracy Application example Measured medium: Steam T1: Conventional welding-type protective tube form 2 acc. to DIN 4772 (pipe 9 x 1mm (0.5 to 0.04 inch)) T2: Pipe collar for tube OD 25.4 mm (1.0 inch) acc. to BS 4825 with measuring insert (fast response) 10 (266) Temp. C ( F) 100 (212) T1 T2 10 C (266 F) 129,5 C (265.1 F) 40 (104) Result The pipe collar provides almost identical results compared to an inline temperature 0 (2) Time [sec] The temperature sensor with pipe collar is used for temperature monitoring, particularly for sterile applications in the food and pharmaceutical industries. Temperature measurement is possible following simple, fast assembly on any existing pipeline system. It is not necessary to interrupt the pipeline or to carry out welding. Assembly on the pipeline is simply carried out by adapting the two halves of the collar. The device can be optionally supplied with an integral transmitter. Function Features Temperature measurement free of dead space Can be retrofitted onto existing pipelines Matches all common nominal pipe diameters Optimum temperature measurement using metallic pressing system Insulating collar made of temperature-resistant plastic, easy to clean Measuring range -20 to +200 C (-4 to +92 F) Replaceable Pt100 measuring insert; thus no changes in measuring setup Calibration possible Transmitter can be integrated (4 to 20 ma or PROFIBUS PA) Mode of operation The temperature measurement is carried out using a Pt100 measuring element. An integral metallic pressing system guarantees optimum heat transfer between the pipeline and Pt100. The measuring insert is protected by an insulating sleeve made of temperature-resistant plastic. The complete Pt100 unit can be easily dismounted at any time for calibration; it is not necessary to disconnect the cables from the sensor. The temperature sensor with pipe collar is available with all standard DIN connection heads. Results with steam as measured medium Medium T Schematic representation The result for the actual temperature of the medium T depends on several parameters: Heat transfer of temperature sensor/pipe Conductivity of medium Flow velocity Pipe wall thickness Pipe material Ambient temperature Installation and operating instructions Assembly of the two halves of the pipe collar to the pipe is carried out simply and rapidly by connection of the two M6 hexagon screws. Any positioning is possible, but the Pt100 measurement should preferably be made "underneath" the pipeline to achieve an optimum result. Following mounting on the pipeline, the complete Pt100 housing unit can be dismounted on site by loosening a clamping screw. It is not necessary to disconnect the cable during the usual calibration procedures. T2 T1 Siemens FI /99
