Pressure sensors are generally composed of metal structural parts and circuits, and some transmitters also have a display part, or are used with digital display instruments. The user’s maintenance of transmitter faults is limited to circuit connection inspection, transmitter cleaning, seal replacement, outlet terminal replacement, zero point, range adjustment, etc. The pressure sensor must be installed by the relevant technician without pressure and without power supply. Pressure sensor measurements vary greatly – pressure sensors need to be calibrated regularly. For transmitters with high accuracy, after a period of use (generally 1 year), the transmitter needs to be sent back to the company for calibration, or sent to a measurement and testing agency for calibration. The pressure sensor output signal is unstable – this situation may be a problem with the pressure source. The stressor itself is an unstable pressure; If the pressure value is zero or if the pressure value is confirmed to be stable and the sensor output signal is unstable, there may be overload or improper operation that causes damage to the sensor or instrument. The pressure sensor measures the same pressure value – first check whether the pressure connection is leaking liquid (gas) or blocked. If it is not confirmed, check the wiring method and power supply, if the wiring mode and power supply are normal, check whether the sensor zero output and resistance value are correct, if it is incorrect, it may be that the sensor or instrument is damaged due to improper installation or improper operation.
