Say there are TWO pressure transmitter on same line.

One is steady at 90 barg and other give dips from 90 barg to 88 barg then again achieve value of 90 barg after some time; probable reason unknown.

Hi,

Do you have a spare transmitter or can you replace transmitter A by B to confirm the trend ?

Did you ask your E&I engineer to check the cable from field to DCS ?

My 2 cents
