AXLE BEARING TEMPERATURE MEASUREMENT

Description and application:

The KTR 156 / R resistance temperature sensor is designed for measuring the temperature of solid substances. In the application segment of rail vehicles, it is planned to measure the temperature of the bearings of the axles of the wagons. The configuration of the sensor depends on obtaining the required resistance of the whole structure, especially against vibrations and shocks.

The temperature range is -40 ° C to 120 ° C and these limits should not be exceeded even for a short time. The sensors can be used for all control systems compatible with the types of detection elements listed in the table of technical parameters. The sensor conforms to the degree of protection IP 68 (1 bar) according to EN 60529, as amended.

The sensor is designed to operate in a chemically non-aggressive environment.
