Product features TEMPERATURE SENSOR WITH ∅ 2 mm HOUSING

The KTG 12 resistance temperature sensor is designed for measuring the temperature of gaseous or liquid substances. In the application segment of railway vehicles, it is intended for use, for example, in the air conditioning system and the temperature control system.

The operating temperature range of the sensor is -50 ° C to 200 ° C. The sensor can be used for all control systems compatible with the types of detection elements listed in the technical parameters table. The sensor complies with the protection index IP 67 according to EN 60 529. The housing diameter of 2 mm guarantees a rapid response of the sensor to temperature changes.

The sensors are intended to operate in a chemically non-aggressive environment.
