传感器的动态性能是否符合要求对测试结果的准确性至关重要。通过压阻式压力传感器的动态校准实验数据,建立其动态数学模型,并由此求出动态特性指标,最后设计出动态补偿数字滤波器,明显提高了传感器动态响应的快速性和展宽了工作频带。 关键词:压力传感器; 动态校准; 建模; 补偿滤波器 Abstract : The dynamic characteristic of sensors is very important to the veracity of the measurement . Using sen2 sor’s dynamic calibrated data ,its dynamic mathematical model can be established and according to the model ,its dynamic performance can be got . A dynamic compensated digital filter is designed ,which shortens the dynamic response time of pressure sensor and widens the work bandwidth evidently. Key words :pressure sensor ; dynamic calibration ; modeling ; compensation filter
