Speed ​​Sensor

Electric vehicle speed sensor is more important sensors are also more sensor applications. By definition , speed sensors are used to measure the speed sensor is divided into speed sensor, speed sensor, wheel speed sensors. Speed ​​Crankshaft Sensor Replacement are used for electric cars motor rotation speed is detected. There are three commonly used speed sensor , namely electromagnetic induction speed sensor , speed sensor photoelectric sensors , Hall-effect speed sensor , are using non-contact measuring principle, in order to enhance detection of security, improve the detection accuracy . The vehicle speed sensor for measuring the speed of electric cars . Speed Car Temperature Sensor signal is mainly used for the dashboard speedometer display and the engine idling , the electric vehicle acceleration during the control. Currently the vast majority of China's electric car speedometer on a car forum selection are converted into speed speed speed of the car . In the case of this car braking , skidding , and the forum because of old and new , friction , road , tire pressure , etc., causing the outer circumference of the level of change will cause the error is too large , or even not work , there are electromagnetic induction speed sensor , photoelectric type, variable reluctance and Hall -style concentration. Generally using electromagnetic induction and the Hall speed sensor on electric vehicles.
