Design of exactitude conductive plastic corner displacement sensor

The conductive plastic sensor of the angle-index potentiometer is designed,which adopts the conductive plastic as sensitive material,the brush discreteness insures the pressure invariableness on the conductive plastic film by the brush patch,and its source uses 10V high precision constant current and voltage.This sensor has high resolution,precision,dependability,anti-jamming ability and long life etc.It may be used in the atrocious weather,the measuring range is 345°,it may rotate freely in 360°with 5×(1±5%)kΩ of the origination resistance and 0.01°of the resolution and ±0.3% of the linearity,it may be applied to control the clique digit and hydraulic pressure pump and robot etc.
