jeep tj speedometer sensor
The vehicle Jeep tj speedometer sensor is the input device of the automobile computer system. It converts the information of various working conditions in the automobile operation, such as vehicle speed, temperature of various media, engine operating conditions, etc., into electrical signals and sends them to the computer, so that the engine is in the best working state. There are many vehicle sensors. When judging the sensor failure, we should not only consider the sensor.The device itself, but the whole circuit with fault should be considered. Therefore, when looking for faults, in addition to checking the sensor, check the harness, connector, sensor and electricity relevant circuits between control units.One of the characteristics of the development of automotive technology is that more and more components adopt electronic control. According to the function of the sensor, it can be classified into measuring temperature, pressure, flow and position. Automobile sensor with functions of device, gas concentration, speed, brightness, dry humidity, distance, etc
Speed sensor is an important sensor for electric vehicles and is also widely used. In terms of its definition, speed sensor is mainly used to measure the transmission of speed. Sensors are divided into speed sensors, speed sensors, wheel speed sensors, etc.Speed sensor speed sensor is mainly used to detect the rotation speed of electric vehicle motor. There are three commonly used speed sensors, namely electromagnetic induction speed sensor. The contact measurement principle is adopted for the sensor, photoelectric induction speed sensor and Hall effect speed sensor to enhance the safety and accuracy of detection.
The speed sensor is used to measure the driving speed of electric vehicles. The vehicle speed sensor signal is mainly used for the speedometer display of the instrument panel, engine idle speed and electric vehicle acceleration control of. At present, most speedometers on electric vehicles in China measure the speed by converting the rotational speed of automobile tires into automobile speed. This is when the car brakes and under slippery conditions, as well as the change of the outer circumference of the tire due to Xinri, friction, road surface, high and low tire pressure, will cause excessive error, or even fail to work. Speed sensing the concentrators mainly include electromagnetic induction type, photoelectric type, variable magnetic Yang type and hall type. Electromagnetic induction type and hall type speed sensors are widely used in electric vehicles.
