Working Principle and Function of Coolant Temperature Sensor

Coolant Temperature Sensor

There are many types of sensors used in cars, which can be roughly divided into:

load sensor can be divided into 50N and 5kN.

Speed sensor: The increment in displacement per unit time is the velocity. Speed includes linear speed and angular speed, and corresponding to the wire speed sensor and angular speed sensor, we all call the speed sensor.

Hall sensor: Hall sensor technology is widely used in the automotive industry, including power, body control, traction control and anti-lock braking system.In order to meet the needs of different systems, hall sensor has switch type, analog type and digital type sensor.

Temperature sensor

In this article, we will have a detailed understanding of the working principle and function of the coolant sensor in the temperature sensor.


Principle:

The coolant temperature sensor is usually installed on the engine body or its cylinder cover, which is directly in contact

with the coolant. It is mainly used to detect the temperature of the coolant when the engine is working in circulation, and transmit the detected results to the electric control unit, so that the fuel injection can be corrected.


Function:

If the temperature of cooling fluid is too high due to the failure of water shortage, wrong ignition time, excessive load, fan, etc., the engine body temperature will rise seriously, so that the engine cannot work normally.

Therefore, in order to detect the cooling fluid temperature of the engine, the designer uses the cooling fluid temperature sensor, which enables the driver to find problems and deal with them in a timely manner.


Any questions regarding the coolant temperature sensor are welcome.
