1 Siemens AG 00 - Transmitter, two-wire system and - Field indicator for 4 to 0 ma Overview Our field devices for heavy industrial use HART, Universal 4 to 0 ma, universal Field indicator for 4 to 0 ma signals The temperature transmitter works where others feel uncomfortable. Benefits Universal use - as transmitter for resistance thermometer, thermocouple element, Ω or mv signal - as field indicator for any 4 to 0 ma signals Local sensing of measured values over digital display Rugged two-chamber enclosure in die-cast aluminium or stainless steel Degree of protection IP67 Test terminals for direct read-out of the output signal without breaking the current loop Can be mounted elsewhere if the measuring point - is hard to access, - 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 protections, for Europe and USA. SIL (with order code C0), SIL/ (with C) Application can be used everywhere where temperatures need to be measured under particularly adverse conditions, or where a convenient local display is ideal. Which is why users from all industries have opted for this field device. The rugged enclosure protects the electronics. The stainless steel model is almost completely resistant to sea water and other aggressive elements. The inner workings offer high measuring accuracy, universal input and a wide range of diagnostic options. Function Configuration The communication capability over the HART protocol V 5.9 of the 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 with the integrated and programmable SITRANS TK. Available for this purpose are a special modem and the software tool SIPROM T. Mode of operation Mode of operation of as temperature transmitter The sensor signal, whether resistance thermometer, thermocouple element or Ω or mv signal, is amplified and linearized. Sensor and output side are electrically isolated. An internal cold junction is integrated for measurements with thermocouple elements. The device outputs a temperature-linear direct current of 4 to 0 ma. As well as the analog transmission of measured values from 4 to 0 ma, the HART version also supports digital communication for online diagnostics, measured value transmission and configuration. automatically detects when a sensor should be interrupted or is indicating a short-circuit. The practical test terminals allow direct measurement of 4 to 0 ma signals over an ammeter without interrupting the output current loop. Mode of operation of as field indicator Any 4 to 0 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 0 ma signal can be represented as any type of unit, e.g. pressure, flow rate, filling level or temperature.
