NTC thermistor for automobile can monitor the temperature of engine coolant and process signal to ECU (Electronic Control Unit) in the cylinder block of automobile engine, which is an indispensable component of automobile engine. In the process of automobile engine operation, it is not only necessary to ensure fast response speed of temperature measurement and accurate temperature judgment, but also to provide real-time temperature to the electronic control unit accurately. Therefore, the VT series of EXSENSE Electronics - NTC thermistor for automobile came into being. With simple structure, fast response speed and high sensitivity, it can effectively play the role of real-time temperature monitoring in the running process of automobile engine.

In order to maximize the temperature monitoring function of NTC thermistor, thermistor is usually encapsulated as sensor, which include metal housing, heat conduction filler, NTC thermistor and connector clip. The metal shell is provided with a sealed inner cavity, the inner cavity is encapsulated with a heat conduction filler; NTC thermistor is embedded in the heat conduction filler; The upper end of the metal shell is provided with an output signal connector clip, the lower end of the connector clip is penetrated into the inner cavity, the lower end of the connector clip is electrically connected with NTC thermistor through a wire, and an insulating layer is arranged outside the wire. The metal shell is formed all in one, with great sealing, and the inner wall of the shell is an insulating layer, which can prevent electricity leakage. The heat conduction filler is a solid heat conduction medium, which ids used to transfer the external water temperature to the NTC thermistor, and can fix the NTC thermistor, so that it has a better temperature measurement environment, improve the measurement accuracy.

Using NTC thermistor for automobile to measure automobile water temperature can provide effective information and judgment data for electronic control unit, and its structure is simple and production efficiency is high. NTC thermistor chip used in thermistor, this chip is a temperature sensitive element, when the temperature decreases, its resistance value increases, otherwise the resistance value decreases. The output of the thermistor chip is an analog signal, which can measure the output temperature of the car water temperature. The thermistor chip can pass the DC 12V voltage, with low power consumption, no drift of the temperature output, high precision and fast temperature response.

VT series NTC thermistor produced by EXSENSE Electronics Technology Co., Ltd. are widely used in automobile, motorcycle and ship as temperature monitoring and temperature controlling component due to their high precision, good heat-resistant circulation ability and high stability.
