      Pressure transmitter common fault analysis!Xi'an Huaheng Instrument Manufacturing Co.,Ltd.
     
      一:无输出
      One:No Output
     
      1、导压管开关没有打开;
      2、导压管路堵塞;
      3、供电电源过低;
      4、供电电源接错;
      5、仪表输出回路故障;
      6、安全栅故障;
      7、表头故障、无法显示;
      8、内部插件接触不良;
      9、电路板故障
     
      1.The switch of the guide pipe is not opened;
      2.The guide pipe is blocked;
      3.The power supply is too low.
      4.Connection fault of power supply;
      5.Output circuit fault of instrument;
      6.Safety grid fault;
      7.Head failure,unable to display;
      8.Poor contact of internal plug-ins;
      9.Circuit Board Faults
     
      二、输出过大
      Excessive Output
     
      1、导压管中有残存液体、气体;
      2、电路板故障;
      3、负导压管一次阀没开或者是没开全;
      4、负压管泄露;
      5、安全栅故障;
      6、DCS量程设置过大;
     
      1.There are residual liquids and gases in the guide pipe;
      2.circuit board fault;
      3.negative guide pipe primary valve is not opened or not fully opened;
      4.negative pressure pipe leakage;
      5.safety grid fault;
      6.DCS range setting is too large;
     
      三、输出过小
      Third,too small output
     
      1、正导压管堵;
      2、平衡阀漏或者没关死;
      3、电路板故障;
      4、正导压管一次阀没开或者是没开全;
