    Tips: Why the pressure transducer has no output?

    1. When the pressure transducer is used with a display instrument, if there's no display on the instrument, it should be judged first whether the pressure sensor has no output or the display instrument is faulty. Measure the output of analog pressure transducer with a multimeter to see if it has a current output of 4-20mA. If the pressure transducer is used with a signal isolator and DCS, it can be judged by measuring the current with a multimeter.
    2. If the pressure transducer doesn't have output, check firstly whether the 24V power supply is normal. If the 24V power supply and power supply are normal, but the pressure transducer still has no output, check whether the power cord is connected reversely, whether the positive and negative poles of the signal are connected incorrectly. If they are, check whether there are open circuit faults in the whole circuit.
    3. If all above inspections are normal, the hardware of the pressure transducer may break. If the circuit board of pressure transducer is damaged, it directly leads to no current output. Overload or over-voltage of the pressure transducer will also lead to damage of its measuring component, which may also lead to no current output; Damage of the transducer's gauge outfit would also lead to no current output. Short-circuit the gauge outfit directly with two wires and it will be normal after short-circuit, indicating that the gauge outfit is damaged. If the LCD head has no display, check the LCD board first, and then check the circuit board. If there's still no output, check the EMI board and circuit board.
