  Kathy EvansAug 11, 2025
  If your WIKA Transmitter shows a steady signal despite pressure changes, it might be due to: * **Blocked Pressure Entry:** The pressure entry could be blocked. Check the tailpipes and pressure entry bore, and carefully clean them if necessary. * **Electronic Defect:** An electronic defect caused by incorrect supply voltage or external voltage might be the problem. Return the transmitter to the manufacturer for repair. * **Overpressurisation:** The transmitter may have failed due to overpressurisation. Return the transmitter to the manufacturer for repair.

  If the full span reading on your WIKA Transmitter is too low, it could be due to: * **Low Supply Voltage:** The supply voltage may be too low. Adjust the supply voltage. * **High Load Impedance:** The load impedance might be too high. Consider the permissible maximum load. * **Incorrect Span Adjustment:** The span adjustment may have been made incorrectly. Re-calibrate the transmitter.
