      Pressure transmitters inevitably have a variety of faults in the process of use, there are many influencing factors, the following company to introduce you to several common types of faults, I hope to help everyone.
      1. Line fault: When a line fault occurs, the computer displays an abnormal value, and the transmitter junction box is opened to check whether there is a virtual connection, short circuit or disconnection in the line. The power supply, the shaking insulation and the quantity resistance are used. And other methods to troubleshoot;
      2, the output signal is zero: first check whether there is pressure in the pipeline, whether the instrument is normally powered, then check whether there is a phenomenon of reverse polarity of the power supply, and finally check the electronic circuit board, pressure sensitive membrane head, transmitter power supply voltage, etc.;
      3, the pressure does not respond: if the pressure does not respond, it is necessary to check whether the valve of the pressure tube is normal, the transmitter protection function jumper switch is normal, the pressure tube is blocked, check the white feeder zero point and range, replace the transmission Sensing film first class.
