hello,
In our site one of gas turbine liquid fuel nozzle differential pressure transmitter reading of pressure on HMI is not correct its reading (-21 bar) at 0 bar and its not changing when changing the pressure.
I checked the mA output its 4 mA at 0 bar and the reading of the transmitter on LCD screen is correct and changing with the pressure and also the mA output is changing with pressure.
the problem is the reading on HMI still -21 bar and didn't changed with pressure
I checked the wiring and I found it ok. for the doubt I replaced the transmitter by another one and I found that the reading on HMI is correct.
Please advise me
Thanks
