For temperature ranges –60°C to +200°C

Resistance temperature sensors are designed for monitoring the temperatures of fluids, air or other gases.

The sensing element is a platinum Pt 100 thermosensor with temperature dependent resistance values, according to the standard ČSN 25 8306. The sensor is built into a protective housing from corrosion-proof steel.  The housing is hexagonal in shape and comes with a fastening thread for attaching the sensor to the object and has a head with a fork for electrically connecting the sensor.  Sensor terminals pass through the WK 46 248 fork.

The complete product comes with:

  • resistance temperature sensor
  • ring (12´18 or 16´20) ČSN 02 9312.2
  • cable socket
