The appearance of the car has facilitated our travel. As one of the important means of transportation, automobiles are composed of different electronic components, including thermistors.
A thermistor is a solid-state component composed of semiconductor materials. Thermistor is sensitive to temperature and its resistance value changes with temperature. The rise or fall of the temperature will affect the change of the resistance value of the thermistor.
Thermistors include positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC). The resistance value of the positive temperature coefficient thermistor increases with the increase of temperature. The resistance value decreases with increasing temperature.
Thermistors are used in automobiles because of their high temperature sensitivity, wide operating temperature range, small size, good stability, strong overload capacity, no loss, and no hysteresis. It is used in various aspects such as automobile temperature inspection and test, automobile motor and protection system, liquid level inspection and test, etc.
1. Temperature Check and Test
Thermistors are mainly used for temperature control, inspection and testing of air conditioners in automobiles, including engine coolant temperature, intake temperature, exhaust temperature, fuel temperature, oil temperature, transmission oil temperature, seat heating, catalytic converter, windshield Anti-frost of glass, etc.
2. Motors and Protection Systems of Automobiles
In automotive motors and protection systems, thermistors are used in door locks, sunroofs, seat adjustment devices, windshield wiper motors, etc.
3. Liquid Level Inspection and Test
Thermistor can be used as a sensor for various fluid level measurement in automobiles, such as brake fluid level inspection and testing, engine oil and cooling water level monitoring, fuel level monitoring, etc.
With more and more people buying cars and the continuous improvement of automotive technology, the demand for automotive thermistors will also increase, and the requirements for thermistors will increase accordingly. Therefore, when choosing a varistor be sure to choose a thermistor with excellent quality.
