Temperature sensors and switches
MOTOMETER temperature sensors have a NTC resistor, that records the temperature of oil, water or air and forwards the measurement result to a temperature display.
Brass casings are used, along with a special gel in the sensor housing, for the fast transfer of the detected temperature with little loss.
Operation is possible with 12 Volt or 24 Volt on-board supply system. The temperature range is between 40 °C and 120 °C or between 50 °C and 150 °C, depending on the type.
The following temperature sensors are available:
- Temperature sensor (40 °C – 120 °C)
- Temperature sensor (50 °C – 150 °C)
- Temperature sensor with warning contact
- Temperature switch
