What is the principle of a vehicle speed sensor?
1 Answers
Vehicle speed sensor operates on the following principles: 1. The output signal of a vehicle speed sensor can be a magnetoelectric AC signal, a Hall-effect digital signal, or a photoelectric digital signal. 2. The vehicle speed sensor is typically installed in the drive axle housing or transmission housing. It then displays the vehicle's speed through pointer deflection or generates alternating current signals, usually consisting of a magnetic core with two terminal posts and a coil. 3. These two coil terminals serve as the sensor's output ports, which are subsequently converted into current amplitude to indicate vehicle speed.
