| Abstract: | Two schemes measuring the sensor signal were proposed upon introducing a non-contact area-changing capacitive angular sensor.Considering its better performance realized in the digital way,the measuring circuit based on CPLD was constructed.The phase detecting and counting of the sensor signal has achieved in virtue of the complex programmable logic device.The circuit's better precision,faster response time,stronger anti-interference ability and perfect stability are validated by the experiments for the circuit and error analysis. |
