The intelligence, automation, digitalization and informatization of industrial production are the direction of future development, the international trend is so, and the trend of domestic industrial development is also the same, and the on-site verification of the transmitter is necessary in the industrial production process. On-site verification of the transmitter can effectively control the probability of measurement error problems and improve the overall efficiency. Before the on-site verification work is officially carried out, the connecting pipe between the pressure transmitter and the pipeline should be completely disconnected, the electrical connection between the pressure transmitter and the control center should be completely disconnected, and then the residual impurities in the pressure chamber of the transmitter should be eliminated, and the electrical signal standard should not be directly connected in series or parallel into the line. Special attention should be paid to the differential pressure transmitter before cutting off the pressure source should first open the balance valve, and then close the high and low pressure valves on the impulse pipe, and remove the high and low pressure exhaust hole plug, the pressure source in the actual verification/calibration process is generally entered by the transmitter high pressure port position, low pressure port and atmosphere are connected together. The regulations require that if the selected pressure transfer medium is liquid, the reference plane of the transmitter pressure port and the lower end face of the piston (or the reference plane of the standard pressure port) of the piston pressure gauge pair should be on the same horizontal plane.
