The KTR 021V resistance temperature sensor is designed to measure temperature of gaseous or liquid substances. In the application segment of Railway Vehicles, it is used for example for specific needs of temperature measurement on engines, both compression ignition engines and electric engines, and on gearboxes or machines and equipment, for which operation vibrations are typical.
The temperature range is -50 °C to 150 °C and these limits must not be exceeded even for a brief period. The sensors can be used for any control systems compatible with types of sensing elements listed in the table of technical parameters. The sensor meets ingress protection IP 67 according to EN 60 529 standard, as amended.
The sensors are intended for operation in chemically non-aggressive environment.
