Check the size if the size of the mounting holes is inappropriate, melt pressure sensor in the installation process, the threaded portion is very susceptible to wear, it will not only affect the sealing performance of the filter pressure signal equipment specifications, and the sensor can not be fully play a role, and may even produce a security risk. Only suitable mounting holes to be able to avoid wear and tear thread (thread industry standard 1 / 2-20UNF2B), usually using the mounting holes on the mounting holes measuring instrument for testing, to make appropriate adjustments. Pressure sensor failure prone pressure transmitter output does not change the pressure signal is cleaner production, and then a sudden change in pressure transmitter output, relief can not go back to zero filter pressure transmitter signal, a very There may be a pressure sensor seal problem. Common reason is due to ring size filter pressure signal parameters, the sensor after tightening ring is compressed into the sensor impulse blockage sensors inside the mouth, when the pressure medium pressure get in, but when the pressure suddenly rushed to open the sealed ring, the pressure sensor varies under pressure. Exclusion of this failure is the best way to remove the sensor directly observe the zero level is normal, if normal zero replaceable seals try; filter pressure signal specifications, Puyang filter pressure annunciator, Xinfeng Xinxiang City, Xinfeng by sensing purification technology Limited.
