Product features Probe for secondary temperature measurements of electrical resistances of electrodynamic cut-offs

The KTR 107 resistance temperature sensor is designed to measure the temperature of gaseous or liquid or solid substances. In the application segment of rail vehicles, the sensor is intended to be used for the secondary measurement of the temperature of the electrical resistances of the 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 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 sensors comply with protection IP 65 according to EN 60529, as amended.

The sensors are intended to operate in a chemically non-aggressive environment.
