Engine Coolant Temperature Sensor

With the help of diligent and adept professionals, our organization is prominent Exporter, Manufacturer, Distributor & Supplier of Engine Coolant Temperature Sensor in Dongguan, Guangdong, China.
The inside of the sensor is a semiconductor thermistor, The lower the temperature, the greater the resistance;Conversely, the smaller the resistance,Installed in the engine cylinder block or cylinder cover on the water, Direct contact with the cooling water,Thereby obtaining the temperature of the engine cooling water.The electronic control unit measures the temperature of the engine cooling water according to the change,The lower the temperature, the greater the resistance; the other hand, the smaller the resistance.The electronic control unit according to the measured change in the temperature of engine cooling water,As the fuel injection and ignition timing of the correction number.Simply means that we can now understand the car running state by engine water temperature,Stop or movement,Or movement of the time how long the like.

Weichai WP10 cooling water temperature sensor structure:
Its internal is a semiconductor thermistor,The lower the temperature, the greater the resistance;On the contrary resistance smaller.The electronic control unit measures the temperature of the engine cooling water according to the change,As the fuel injection and ignition timing of the correction number.
