VDO Cooling Fluid Temperature Sensor, +40 to 120 °C, 5/8-18 NF-3, with 95 °C alert

The VDO cooling fluid temperature sensor with a 5/8-18 NF-3 connection is used to measure cooling fluid temperature. It operates within the range of +40 to 120 °C and outputs a resistive signal intended for a compatible temperature indicator.

The outlet range of 287.4 to 22.7 ? must match the electrical specifications of the gauge or indicator being used. An identical display range alone is not sufficient to guarantee compatibility. The 95 °C ± 3 °C alarm contact provides a separate function from the measurement, designed to control a compatible warning light.
