Abstract:
An absolute angular sensor of a steering system for vehicles, comprising:a power supply for supplying power; a pulse supply for generating pulses; a linear variable displacement transducer, operated by a pulse outputted from the pulse supply, for sensing a variable displacement of a rotator disc mounted at a steering shaft when the steering shaft operates, and outputting a signal in proportion to the sensed rotation displacement; a demodulator for demodulating the signal outputted from said linear variable displacement transducer by rectification to produce an external displacement output; a DC (Direct Current) amplifier for amplifying the rectified external displacement output from the demodulator into a certain level; a DC (Direct Current) output part for providing a signal output amplified by the DC (Direct Current) amplifier; and a sensing coil wound around a bobbin at both sides of an operation coil and being applied with voltage when the operation coil is in its operation mode.
