Abstract The article conducts laboratory calibration of PTB210 and PTB220 pressure sensors based on the Pressure Sensor of Automatic Meteorological Station,obtains accurate measurement error correction values of the sensors,and based on this,introduces in detail the method of adjusting the correction values of pressure values at each calibration point for sensors with out of tolerance anomalies.This achieves accurate correction of measurement errors of pressure sensors,meets the maximum allowable error value requirements of corresponding regulations,extends the business operation cycle of pressure sensor equipment,reduces equipment operation and maintenance costs,and has high business availability.
