特性 Features

The module is an affordable, digital transducer in miniaturised construction for Pt1000 measuring resistors. The module converts the resistance characteristics 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 accuracy 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 characteristics; 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.
