The KTG 3 and KTG 3A resistance temperature sensors are designed for measuring the temperature of gaseous or liquid substances.

In the application segment of rail vehicles, they are intended to be used for example in the air conditioning system and the temperature control system.

The operating temperature range of the KTG 3 sensor is -50 ° C to 200 ° C and that of KTG 3A is -50 to 260 ° C.

The sensors can be used for all control systems compatible with the types of detection elements listed in the technical parameters table. The KTG 3 sensor conforms to the degree of protection IP 67 and the KTG 3A sensor meets the degree of protection IP 64 according to EN 60529.

The 3mm case diameter guarantees rapid sensor response to temperature changes.

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