Design of contactless capacitance angle sensor based on AD7745

LIANG Sheng1,HUANG Zhao-hong1,LI Xin-hui2(1.Laboratory of Photonic Information Technology,South China wormal University,Guangzhou 510006,China;2.The 49th Research Institute,China Electronics Technology Corporation,Harbin 150001,China)  
A contactless capacitance angle sensor is designed.It has a simple structure and a better linearity.AD7745 and micro control unit are used to process the capacitance signal.It makes the circuit simple and easy to application.The output voltage varies from 5 mV to 4.95 V as the angle changes from 0° to 90°.The sensor precision is up to 5′.
