Certifications Of The Water Coolant Temperature Sensor
The role of water temperature sensor
Strictly speaking, the water temperature sensor is divided into two
categories. No matter which type, its internal structure is a
thermistor, and its resistance is between 275 ohms and 6500 ohms.
And the lower the temperature the higher the resistance value, the
higher the temperature the lower the resistance value.
1)The function of the first type of water temperature sensor is relatively simple, through its internal resistance change to change the current through the sensor to change the change in the resistance of the sensor to drive the change of the water temperature meter, and indirectly tell people the working temperature of the engine.
2)The second category, the water temperature sensor has no change in structure, but its function is to provide an analog signal of temperature change to the engine control unit. Its power supply voltage is a 5V power supply provided by the control unit, and the signal returned to the control unit is a linear change signal of 1.3V-3.8V. The main function is to tell the current temperature of the engine control unit. In turn, its signal is extremely important for the control unit. The main reason is that the engine has different working methods at different working temperatures.
