Temperature sensor 

The temperature sensor is equipped with CANopen or J1939 for protocol support. In addition, it has an ECE type approval for use on public roads, and possesses a configurable averaging function.


The main challenge for temperature sensors used in mobile machines is the measurement directly in the medium and the rapid recording of temperature changes. On the T01, the parts coming into contact with media have been produced from stainless steel and guarantee, in combination with the welded temperature element, maximum media compatibility and fast response times. With the best EMC characteristics and high levels of shock and vibration resistance, the T01 can be used in demanding fields of application such as mobile hydraulics.
