ktr 069/r measuring temperature of cooling air of traction electric motors

The KTR 069/R temperature sensor is designed to measure temperature of gaseous, liquid or solid substances. In the application segment of Railway Vehicles, it has been produced to measure temperature of cooling air of traction electric engines of shunting locomotives. A special adapter with a bayonet mount prevents the sensor from loosening.
The temperature range is -40 °C to 120 °C and these limits must not be exceeded even for a brief period. The case of the temperature sensor and the adapter with bayonet mount is made of stainless steel. The sensor can be used for any control system compatible with types of sensing elements listed in the table of technical parameters. The sensor meets ingress protection IP 67 according to EN 60529 standard, as amended.
The sensor is intended for operation in chemically non-aggressive environment.
