ktr 149 measuring temperature of rail for automatic heating of track exchanges

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.it is intended to measure temperature of rails and is a part of the system for automatic heating of railroad switches. The sensor has double insulation, which provides high value of electrical breakdown in its own sensor.

The temperature range is -40 °C to 100 °C and these limits must not be exceeded even for a brief period. The sensor meets ingress protection IP 68 (1 bar) according to EN 60529, as amended. The KTR 149 temperature sensor is attached to the rail from the bottom side with a special elastic holder D001 or D006 (depending on the rail) that is delivered separately. The sensor design ensures meeting the conditions for security equipment according to requirements of EN 50125-3 standard and EN 60068-2-1 and EN 60068-2-2 standards. Because of this, they can be used to measure surface temperature of the rails. The sensor can be used for any control systems compatible with types of sensing elements listed in the table of technical parameters.

The sensor is intended for operation in chemically non-aggressive environment.
