Problem with pressure sensor sealing ring
The output of the pressurized transmitter does not change, the output of the re-pressurized transmitter changes suddenly, and the zero position of the pressure relief transmitter cannot be returned, which is likely to be the problem of the pressure sensor sealing ring. It is common that due to the specifications of the sealing ring, after the sensor is tightened, the sealing ring is compressed into the sensor pressure port to block the sensor. The pressure medium cannot enter during pressure, but the sealing ring is suddenly opened when the pressure is high, and the pressure sensor is under pressure. change. The best way to eliminate this kind of fault is to remove the sensor and directly check whether the zero position is normal. If the zero position is normal, replace the sealing ring and try again;
