Function Of Active Sensor System; Active Sensor Element Of Encoder Wheel - SSANGYONG 2004 Rexton 2.7XDi Workshop Manual

WHEEL SPEED SENSOR
Active Wheel Sensor
- Measuring bridge with four resisters
- Measuring the current
- Supplying the voltage (12 V)
- Amplifier/comparison measuring device

Function of Active Sensor System

The basic tone wheel and the magnetized encoder wheel to
activate the sensor. When the vehicle is moving, the sine wave
signal is changed in the magnetic field of wheatstone bridge
due to the rotation of tone wheel. This can be done directly by
ABS control unit.
Active Sensor Element of Encoder
Wheel
This sensor has the measuring bridge integrated plastic hous-
ing and is fixed to small permanent magnet. Four lead wires
that receive electrical output value are connected to the IC
integrated plastic housing. Two connecting pins are used for
signal output and voltage supply.
