Abstract
A non-contact capacitive angle sensor was designed. Through capacitance convertor-integrated circuit CAV424 and voltage-current convertor -AM402 which developed by AMG in Germany, the signal of capacitive sensor is converted into standard industrial current output which from 4 to 20 mA. The system can realize angle non-contact measurement accurately from 0 to 900 with high linearity current output. It has anti-interference ability and can decrease error in measurement.
