What is the method to distinguish the three wires of an odometer sensor?
1 Answers
The method to distinguish the three wires of an odometer sensor depends on whether the sensor is magnetic or Hall-effect type. Principle: The odometer sensor measures the speed of the wheel based on the principle of rotational speed measurement. According to the diameter of the wheel, each measurement cycle corresponds to one full rotation of the wheel, and the total distance traveled is calculated by accumulating the number of wheel rotations. Purpose: The odometer sensor, located on the differential or half-shaft, detects the number of rotations, typically using Hall-effect or photoelectric methods to sense signals. The purpose is to effectively analyze and determine the vehicle's speed and mileage by counting the odometer readings. Since the angular velocity of the half-shaft and the wheel is the same, and the tire radius is known, the mileage can be directly calculated using the odometer parameters.
