As a key component of the automotive engine cooling system, the core task of the coolant temperature sensor is to monitor the engine coolant in real time with the help of NTC thermistor to ensure that the engine always maintains stable operation. Utilizing the unique negative temperature coefficient characteristic of NTC thermistor, the coolant temperature can be converted into quantifiable electrical signals, which can be regulated by the automotive ECU to help the car engine start smoothly.

Due to the working state of the automobile engine is easily affected by the surrounding environment, EXSENSE Electronics has independently developed and mass-produced VT series automotive NTC thermistor to assist the coolant temperature sensor in providing accurate temperature signals to ensure that the engine can work normally under different working conditions. This is made possible by the VT series automotive NTC thermistor:

1. High accuracy, which provides strong support for the accurate temperature measurement of coolant temperature sensor. After the NTC obtains the engine coolant temperature, it provides temperature data to the ECU through the coolant temperature sensor, which then accurately adjusts the engine's fuel injection volume, ignition timing and other key parameters based on the data, so as to optimize engine performance and avoid fuel waste, engine wear and other conditions.

2. Respond quickly, monitor coolant temperature in real time. The operating conditions of the engine are complex and changeable, and coolant temperatures fluctuate accordingly. The thermistor is sensitive to temperature, so that the coolant temperature sensor can detect the subtle changes in engine coolant temperature in time and transmit the temperature change signal to the ECU to adjust the engine working state in time.

3. High temperature resistance, ensuring the long-term stability of the coolant temperature sensor in the harsh environment of the engine. When the engine is running at high temperatures, the electrical properties of EXSENSE Electronics's VT series automotive NTC thermistors will not drift or be damaged due to excessive high temperature, ensuring that the coolant temperature sensor can continuously and accurately monitor the coolant temperature. This allows the engine cooling system to maintain the normal operation of the car according to the accurate temperature signal provided by the NTC thermistor under long-term climbing, heavy load driving and other working conditions, and will not cause failure due to abnormal temperature monitoring or failure.

To sum up, under the combined effect of the outstanding electrical characteristics of the VT series automotive NTC thermistor from EXSENSE Electronics, the coolant temperature sensor not only ensures the stable operation of the engine, improves the power performance of the vehicle, but also reduces energy consumption, which is very important for engine operation regulation and coolant temperature monitoring.
