Why JUMO Transmitter has no output signal?
- B
  Brandy CurryAug 9, 2025
  The JUMO Transmitter might not be sending an output signal due to several reasons. It could be due to no supply voltage, so check the supply voltage. There might be a cable break or incorrect connection, so check the connecting cables. Another reason could be no input pressure, in that case check the connection to the pressure medium. Finally, there may be a fault in the pressure transmitter, caused by impermissible operating conditions, in this case return the pressure transmitter to the supplier, with a detailed description of the fault.

What to do if JUMO dTRANS p30 output signal is too low?
- C
  Christopher RichardsonAug 17, 2025
  If the JUMO Transmitter's output signal is too low, it could be due to a high burden in the current output signal or a low burden in the voltage output signal; in this case, change the burden on the measurement circuit. Alternatively, the supply voltage may be too low, so alter the supply voltage.

Why does the JUMO Transmitter output signal stay constant even though the pressure changes?
- A
  Andrew WrightAug 25, 2025
  A constant output signal from the JUMO Transmitter, despite pressure changes, can occur if the measurement system has been destroyed by excessive pressure. It also may happen if the output signal is being distorted by current limiting due to overvoltage, in this case provide the correct supply voltage. Another cause may be a blocked measurement point, so check the measurement point and clean or replace it if necessary. Finally, the measurement range may be too small, so return the pressure transmitter to the supplier, with a detailed description of the fault.

  A JUMO Transmitter's output signal might be too high if the selected measurement range is too low; in this case, return the pressure transmitter to the supplier, with a detailed description of the fault. Also, the electronics of the pressure transmitter could be faulty, or the supply voltage could be too high.
