ktr 107 for secondary temperature measurements of electric resistors of electrodynamic breaks

The KTR 107 resistance temperature sensor is designed to measure temperature of gaseous or liquid or solid substances. In the application segment of Railway Vehicles, the sensor is intended to be used for secondary measurement of temperature of electrical resistors of electrodynamic brakes of electric and diesel-electric locomotives.

The temperature range is -40 °C to 400 °C and these limits may be exceeded 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 sensors meets ingress protection IP 65 according to EN 60529, as amended.

The sensors are intended for operation in chemically non-aggressive environment.
