Anti-lock braking system
abs sensor is used in motor vehicle ABS (Anti-lock Braking System). In ABS system, speed is monitored by inductor sensors. abs sensor outputs a set of quasi-sinusoidal AC electrical signals through the action of gear ring that rotates synchronously with the wheel, its frequency and amplitude are related to wheel speed. The output signal is transmitted to the ABS electronic control unit (ECU) to realize the real-time monitoring of wheel speed
Output voltage detection
Inspection Items:
1, output voltage: 650 ~ 850mv(1 20rpm)
2, output waveform: stable sine wave
2. Low temperature durability test of abs sensor
Keep the sensor at 40℃ for 24 hours to check whether the abs sensor can still meet the electrical and sealing performance requirements for normal use
