KTG 6/R and KTG 6E/R TEMPERATURE SENSOR THREAD M6, OK 12

The KTG 6/R and KTG 6E/R temperature sensors are designed to measure temperature of solid substances. In the application segment of Railway Vehicles, the temperature sensors are used for example to measure surface temperature of baseboards of converters and coolers of performance elements of electric locomotives (drive units) where, due to the lack of space, the supply cable is needed to guide at a right angle to the base board and in close proximity to the performance elements under power.The sensor is attached to the surface of measured parts with the thread M6, which is s part of the sensor.

The temperature range of temperature sensors KTG 6/R and KTRG 6E/R 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 sensor meets ingress protection IP 67 according to EN 60529 standard, as amended.

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