关键词Pressure Transmitter Sensor Calibration The Least Square Method
摘要The accuracy of capacitance pressure sensor is easily disturbed by work environment. In order to improve the accuracy of pressure sensor, the paper researches on the sensor calibration of pressure transmitter based on the least square method. The measurement circuit is designed to convert the output of sensor from the capacitance value to the cycle value. Working quadric surface is fitted with the value of environmental temperature, the output of pressure sensor and setting pressure by the least square method. The pressure transmitters can accurately measure at different temperatures by the experiment.
