Features
The module is an affordable, digital transducer in miniaturised construction for Pt1000 measuring resistors. The module converts the resistance charac- teristics of a Pt1000 sensor into an industrial standard signal of 0...10 V (3 wire connection) or 4...20 mA (two wire connection). With this, the operation of sensor is possible with control systems, for example, an SPS with voltage or current input. With the most modern digital ASIC technology, an outstanding measuring ac- curacy and long term stability is guaranteed in the application. The resistance curve of the sensor element is linearised over a second order polynomial in accordance with DIN EN 60751 and the measuring amplifier is temperature compensated. The module is calibrated at three points at works as per the resistance cha- racteristics; a further adjustment by customer is not necessary. The robust module is meant for continuous application in industrial environment and is protected against over voltage and transients with the help of a varistor. Note: The scope of supply is without Pt1000 measuring resistor, please additionally include a suitable model with the order.

Technical changes reserved 0141 0316-192 13.01.2021 Pt1000 sensor module with standard signal output Drawing - Module Drawing - Module with plug Connection of sensors The Pt1000 sensor element is soldered at the two upper pins as shown above. The other pins are not allowed to be connected or short circuited. The connection must be done very carefully because of the very small pin spa- cing. Any type of Pt1000 sensors like thin film chip resistances, wire wound sensors or even MIMS resistance thermometers can be used as long as the resistance characteristics are as per DIN/IEC 60751. The connection lead to the sensor should be as short as possible, in order to avoid measuring error due to distortion in resistance characteristics. Note: The sensor element is not in scope of supply (please include separate- ly with order). Calibration The measuring probes are calibrated at works with reference to Pt1000 re- sistance characteristics (DIN EN 60751), hence full interchangeability of the sensor element is guaranteed corresponding to the accuracy class. Because of the high quality platinum resistance, the probes are long term stable and maintenance free. Hence, a re-calibration is not required. Guarantee On our high quality measuring products, you get a guarantee of 24 months. Mechanically damaged sensors or tampering into electronics makes the sensors devoid of guarantee claims. Calibration services are not covered in the guarantee. Connection Important hint: The OWI-connection of 20 mA module also should not be connected to any wire! The connection of the module (type –10V/20MA) can be identified as per the picture in the next page. Wrong connection can lead to failure of the module! The connection of the module is done at the lateral soldering surfaces and pads as per the sketch. The dimensions and contact layout also enables direct soldering of industrial plugs as per DIN 43650. On demand, the modu- le can be assembled into a housing or provided in moulded form. Suitable housings are also available on enquiry. The model with voltage output requires operating voltage. In order to avoid measuring error due line resistance every single module has to be connec- ted with three wires (VCC, OUT and GND) directly to the measuring input. The model with current output is supplied by the loop current and hence it is connected with two pin system. The pin SHIELD is optional and can be used in application with shielded connection cable for connecting to the shielding.
