Product features KTR 141 resistance temperature sensors

The KTR 141A / R a KTR 141E / R resistance temperature sensors are designed for measuring the surface temperature of solid substances with a smooth surface. In the Railway Vehicle application segment, the sensors are intended, for example, to measure the surface temperature of the baseboards of converters and coolers of performance elements and of emergency battery sources of electric locomotives.

The temperature range is -40 ° C to 120 ° C and these limits should not be exceeded even for a short time. The sensor can be used for all control systems compatible with the types of detection elements listed in the technical parameters table. The sensor conforms to the degree of protection IP 65 according to standard EN 60529, as amended.

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


Type tests are carried out by a notified body according to standard EN 50155, as amended, Railway applications - Electronic equipment used on rolling stock, Art. 12.2.9, 12.2.11

- Insulation test according to EN 50155, as amended
