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. MOTOMETER temperature sensors with a warning contact have a NTC resistor, a brass casing and a special gel for rapid temperature transfer with little loss.
The pre-tensioned bimetal strips are relaxed when the defined temperature is reached and the contact close. Operation is possible with 12 Volt or 24 Vol on-board supply system. The switching capacity is 3 W.
