Pressure transmitterOn site fault inspection: The majority of faults that occur on construction sites are caused by improper use and installation methods of pressure sensors, which can be summarized into the following aspects.
1. Leakage or blockage of the pressure pipe, residual gas in the filling pipe or residual liquid in the filling pipe, sediment in the flange of the transmitter process, forming a measurement dead zone.
2. The transmitter wiring is incorrect, the power supply voltage is too high or too low, and there is poor contact between the indicator head and the instrument wiring terminal.
3. The installation did not strictly follow the technical requirements, and the installation method and on-site environment did not meet the technical requirements.
4. One component (orifice plate, remote measurement connector, etc.) is blocked or installed incorrectly, and the pressure point is unreasonable.
