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.

In addition to the listed standard temperature sensors, we can also offer you customised solutions.

Temperature sensor with warning contact

Temperature sensors with a warning contact are used in vehicles and machines to record the temperature of oil, water
or air and to forward the measurement result to a temperature display.
A warning contact is closed at the same time as a defined temperature is reached.

The resistance characteristic is identical for all sensors
60 °C      221,2 Ohm
90 °C         83,0 Ohm
100 °C        36,5 Ohm

Temperature switch

Temperature switches are used in vehicles and machines to record the temperature of oil, water or air and to close a
warning contact when a defined temperature is reached.

The MOTOMETER temperature switches have pretensioned bimetal strips.
The use of brass casings and a special integrated gel allows fast temperature transmission with little loss.
When the respective temperature range is reached, the pre-tensioning is released and the contact is closed with a switching capacity of 3 W or 100 W.
Operation is possible with an onboard 12 Volt or 24 Volt mains.
MOTOMETER temperature switches are also available mass-free.
