WD-NPT3-823 NPT3/8 Engine Coolant WaterTemperature Sensor

This is a small and simple type of heat switch. Install on radiator or cooling system piping.

The bimetallic disk is a sensing element that changes its state with the temperature of the coolant. When it reaches a predetermined temperature, the disc snaps, shutting off the circuit that activates the radiator cooling fan.

The heat switch, an updated version of a simple bimetallic disk, turns on a warning light on the vehicle's dashboard to indicate that the coolant has reached its limit temperature.

Universal NPT3/8 oil/Water temperature sensor, this is a single wire sensor for signal to meter that is grounded by thread when the sensor is tightened to the engine/sandwich plate. Single-connection sensor (brass case grounded) Temperature reading range -40 ° C to 150 ° C

The output end of the sensor is fastened by injection molding process, which can withstand high and low temperature and has stable performance.
