Abstract
High-precision pressure sensor is widely used in aviation field,and often faces harsh working environment.In order to make pressure sensor maintain high accuracy in special test condition,the design of sensor performance becomes critical.Reasonable signal conditioning circuit and correct calibration principle can significantly improve the performance of sensor.Through using programmable analog signal conditioner in the signal conditioning circuit of sensor,temperature drift and nonlinearity of the bridge pressure sensitive element are modified real-time,the intelligent self-calibration is realized,and the accuracy and environmental adaptability of the pressure sensor are effectively improved.关键词
