Application:
- Temperature measurement in regulation and measuring equipment.
- Converts the signal from the platinum sensor Pt100 according to IEC 751 to a unified output signal – current loop 4 - 20 mA.
- The powering source of the converter is connected serially with load in the output loop of the converter.
Design:
- Converter circuits made by using thin-layer technology and put using surface assembly into a plastic case.
- The case is designed for building into the sensor head.
- The converter makes the dependency of the output current on temperature linear.
- The conductors from the thermal sensor and the current loop conductors are connected to the screw terminal board. W 073 – three wire connection of the sensor, W 074 – four wire sensor connection.
- Protection against re-poling of the supply voltage, against error shorting or sensor conductor interruption.
- Design in 16 temperature ranges of measuring.
