3 Description of the measuring principle Description of the measuring principle Measuring principle Conductive probes are used for level detection in conductive liquids. The instruments are designed for industrial use in all areas of process technology. Conductive probes detect the product resistance when their electrodes get covered by the product. A small alternating current, measured continuously by the electronics of the compact instrument or a separate signal conditioning instrument, is checked for amplitude and phase position and converted into a switching signal. A conductive probe consists of a ground electrode and a levelrelated measuring electrode. The switching signal is determined by the length or mounting position of the respective measuring electrode. In conductive vessels, the vessel wall can be used as the ground electrode. The measuring probe can then consist of only one measuring electrode. The sensors are maintenance free and rugged and can be implemented in all areas of industrial measurement engineering.. Application examples Overflow protection Measuring system for detection of the max. level in an electrically conductive vessel (e.g. as overflow protection) Pump control is a frequent application in the area of water and waste water. To empty a pump sump automatically with a pump when a certain level is exceeded and to switch the pump off again when the min. level is reached, the pump can be controlled with a conductive measuring probe. Fig. : Pump control with an EL conductive measuring probe Advantages: l Up to five switching points with one sensor possible Dry run protection in pipelines Thanks to its virtually front-flush conical electrode, the conductive level switch VEGAKON 6 is ideal for use in pipelines. Its flowefficient profile does not change the pipe cross section and thus prevents turbulence. The VEGAKON 6 measures the field strength at its tip, and is thus insensitive to buildup. VEGAKON 6 calibrates itself automatically and therefore needs no adjustment. Fig. : Dry run protection in pipelines Fig. : Overflow protection Simple, inexpensive level detection, e.g. as overflow protection in watery liquids. Advantages: l Easy, reliable sensors l Small installation dimensions Advantages: l Insensitive to buildip l Adjustment free l Causes no turbulence l Does not change pipe cross sectional area l Robust and abrasion resistant Pump control Due to the many possible ways of application, conductive level switches are ideal for all measuring tasks in connectionwith water and aqueous solutions. The large number of electrical and mechanical versions guarantees simple integration into existing processes. Conductive Level detection in liquid

6 Mounting instructions Mounting instructions Switching point Mount the probe in such a way that the rod or cable electrodes do not touch the vessel wall during operation. Agitators Due to agitators, vibrations or similar, the probe can be subjected to strong lateral forces. Excessive system vibration or shocks, e.g. caused by agitators or turbulence in the vessel (e.g. from fluidisation) can cause the rod probe to vibrate in resonance. This can lead to increased material stress. Should a longer rod probe be necessary, you can provide a suitable insulated support or guy directly above the end of the probe to stabilise it. In case of strong product movements, foam generation and flow in the vessel, the probe can be also mounted in bypass tubes. Fig. 5: Inflowing medium Pressure/Vacuum The process fitting must be sealed if there is gauge or low pressure in the vessel. Check if the seal material is resistant against the measured product and the process temperature. Insulating measures in metal vessels such as e.g. covering the thread with teflon tape can interrupt the necessary electrical connection to the vessel. Ground the probe on the vessel. Shorten the probe The rods of the probe can be shortend individually. Fig. 4: Fasten the probe Probe Plastic socket on the probe end Probe 4 Plastic socket laterally mounted Inflowing medium If the conductive sensors are mounted in the filling stream, unwanted false measuring signals may be triggered. For this reason, mount the instruments at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur. Metal vessel If probes without ground electrode are used, you must make sure that the mechanical connection of the probe is connected electrically conductive to the vessel to ensure sufficient grounding. Use conductive seals such as e.g. copper, lead etc. Insulating measures such as e.g. covering the thread with teflon tape can interrupt the necessary electrical connection. If this is necessary, use the ground terminal on the housing to connect the instrument with the vessel. A ground electrode must be provided for probes EL 4 and 6 as well as with VEGAKON 66. Non-conductive vessels Generally use probes with a ground electrode in non-conductive vessels, e.g. plastic tanks. Horizontal mounting If you mount a VEGAKON 66 laterally, we recommend mountingit approx. 0 inclined so that the liquid medium can drain off more easily and no buildup can generate on the isolation. 6 Conductive Level detection in liquid

Use conductive seals such as e.g. copper or lead etc. Insulating measures, such as covering the thread with Teflon tape, can interrupt the necessary electrical connection with metal vessels. For this reason, ground the probe on the vessel or use a conductive seal material. Conductive Level detection in liquid 7

8 Electrical connection 4 Electrical connection 4. Preparing the connection Note safety instructions Always keep in mind the following safety instructions: l Connect only in the complete absence of line voltage Take note of safety instructions for Ex applications + L - N In hazardous areas you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units. Select power supply Connect the power supply according to the following diagrams. Oscillator with relay output is designed in protection class. To maintain this protection class, it is absolutely necessary that the ground conductor be connected to the internal ground terminal. Take note of the general installation regulations. As a rule, connect VEGAKON to vessel ground (PA), or in case of plastic vessels, to the next ground potential. On the side of the housing there is a ground terminal between the cable entries. This connection serves to drain off electrostatic charges. In Ex applications, the installation regulations for hazardous areas must be given priority. The data for voltage supply are specified in chapter "Technical data". Selecting connection cable VEGAKON and probes EL are connected with standard cable with round cross section. An outer cable diameter of 5 9 mm ( in) ensures the seal effect of the cable gland. If cable with a different diameter or wire cross section is used, exchange the seal or use an appropriate cable connection. In hazardous areas, only use approved cable connections for approved instruments. Select connection cable for Ex applications Take note of the corresponding installation regulations for Ex applications.

Wiring schematic VEGAKON 6, 66 Relay output Is used to switch external voltage sources to relays, contactors, magnetic valves, horns etc. We recommend connecting VEGAKON in such a way that the switching circuit is open when there is a level signal, line break or failure (safe condition). The relays are always shown in non-operative condition Fig. 9: VEGAKON 6 - transistor output 8 Conductive Level detection in liquid

9 Electrical connection Fig. 0: VEGAKON 66 - transistor output The transistor switches the supply voltage of the electronic module to the binary input of a PLC or an electrical load. Through different connections of the consumer (load), PNP or NPN action can be attained Wiring plan EL, EL, EL 4, EL 6, EL 8 For connection to a signal conditioning instrument You can find the electrical connection of VEGAKON in the product information manual "Signal conditioning instruments for conductive electrodes". You will find suitable signal conditioning instruments in chapter "Technical data". Selecting connection cable To ensure the seal effect of the cable gland, VEGAKON is connected with standard cable with round cross-section. The outer diameter of the cable is stated in chapter "Technical data". Line monitoring To realize a line monitoring, a resistor of 0 kω must be integrated in the connection housing of the probe between terminal and. When a fault message is generated, the switching output is simultaneously activated. If a fault message is not wanted, a bridge must be provided on the signal conditioning instrument instead of the resistor in the connection housing of the probe. The line monitoring is thus deactivated and the fault message rendered invalid Fig. : VEGAKON 6 - electronics with transistor output NPN action PNP action l l With Ex versions, this resistor of 0 kω is already integrated Ex factory in the connection housing of the probe. The Ex measuring system (max. and ground connection cable of the probe to the signal conditioning instrument) is generally monitored for line break.

12 Operation Selection switch: Integration time (4) There are three switches on the DIL switch block by which you can adjust the switching on and off delay. Thus prevents, e.g. the instrument from permanent switching if the level is within the limits. The delay refers to the switching status of both relay outputs. With the switches ( s, 6 s, s) you can set the integration time respectively in the range of 0 to 0 seconds. The times of the activated timers add up. If e.g. the switches s and s are activated, the integration time will be 4 s. Mode adjustment (5) With the mode adjustment (A/B) you can change the switching condition of the output. You can set the required mode (A - max. detection or overfill protection, B - min. detection or dry run protection). Tensile proving ring (7) Loosen the holding screws of the electronics module. Fold the tensile proving ring upward. With the tensile proving ring you can pul the electronics module out of the instrument housing. 5. Adjustment probes EL, EL, EL 4, EL 6, EL 8 The adjustment of probes EL is carried out via a suitable signal conditioning instrument. The adjustment possibilities are specified in the product information manual "Signal conditioning instruments for conductive probes". Conductive Level detection in liquid
