Laboratory Calibration Methods and Common Faults of Pressure Sensors
PTB210 pressure sensor has the advantages of small size and high precision,and is one of the commonly used instruments in automatic weather stations.According to the relevant requirements,it should be submitted to the inspection once a year.Since some common faults will seriously affect the verification efficiency,Shanxi Meteoro-logical Station will verify the pressure sensors of 109 national stations every year.In order to meet the needs of the modernization of meteorological observation business,this paper puts forward the metrological verification method for the existing automatic weather station pressure sensors,and proposes the troubleshooting method by analyzing and summarizing the common faults.
