摘要
Abstract
The inductance displacement sensor is widely used in small displacement detection.However,in some existing engineering sensors measurement precision and sensitivity can not reach the measurement requirements.Based on this problem,a sensor signal processing circuit is improved.An LC circuit is formed by including capacitance in the coil.The LC circuit resonant effect can improve circuit performance and improve the sensitivity of the signal source.Multisim software is adopted to simulate the performance of the half-and-half bridge and the whole bridge circuit when they include a capacitance of a different size capacitance.Matlab is used to fit the curve of the least squares.The capacitance and paralleling method for the optimal performance of the circuit are obtained through comparison.The results show that a little damage to the linearity can double sensitivity.关键词
