ktr 164/r measuring the temperature of coolants batteries or other parts with planner surface

The KTR 164/R resistance temperature sensor is designed to measure temperature of solid substances. In the application segment of Railway Vehicles, the sensor is intended to be used for measurement of temperature of cooler, accumulator or other parts with a flat surface.

The temperature range is -40 °C to 120 °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 sensors meets ingress protection IP 67 according to EN 60529, as amended.

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