speedometer speed sensor 3802020-8E for FAW J6 Jh6 Fawde 6dm truck Spare Part truck accessioris
The speed sensor is a device that converts the movement speed of an object into an electrical signal. It includes two types: linear velocity sensor and angular velocity sensor. Speed sensors are widely used in the automobile detection market, such as vehicle speed sensors, which are used to detect the speed of electronically controlled vehicles and convert this information into electrical signals for use by control computers to control engine idling speed and automatic transmission changes. Torque lock, automatic transmission shifting, engine cooling fan opening and closing, cruise control, etc. The output signal of the speed sensor can be a magnetoelectric AC signal, a Hall digital signal, or a photoelectric digital signal. They are usually installed in the drive axle case or transmission case, and are equipped with a shielded jacket to eliminate electromagnetic and radio frequency interference. This ensures uninterrupted electronic communications and prevents deterioration in driving performance or other problems. Speed sensors not only have important applications in the automotive field, but are also widely used in industrial control, aerospace and other fields. By sensing the motion state of objects and converting it into electrical signal output, they provide basic data for subsequent signal processing. The core component of the speed sensor is the sensing element, such as Hall effect sensor, photoelectric sensor, inductance sensor, etc., which can generate corresponding electrical signals according to the movement of the object.
