The on-site display and the central control display of the pressure transmitter show values that are 10 times lower than those of the pressure gauge.

The pressure gauge shows 4.7 kilograms, while both the reading on the pressure transmitter at the same location and the reading in the control room are 47 KPa. It should show 470 KPa. Could you please tell me what the cause of this is and how to make the adjustment?
Well, it’s not just a matter of adjustment; the key is to determine which pressure level is appropriate, or if there are problems with both
Could it be that the pressure tap is blocked? Replace the pressure gauge on site and check whether there is something wrong with it; verify whether the actual pressure is indeed 4.7 kilograms. After ruling that out, check whether the pressure tap of the pressure transmitter is blocked, whether the transmitter module is in good condition, and whether the settings such as the range are correct – examine everything one by one.
The pressure gauge is accurate; the pressure on site is 4.7 kilograms.
The reason for this is that adjusting the configuration unit will fix it
Both the parameter settings for the pressure transmitter and those for the display instruments in the control room are missing one parameter; resetting the parameters resolves this issue.
Range adjustment can be made using the handheld operator; it is modified through DCS configuration in the central control system
Just change the units in DCS.
With such limited information about the reaction issue, it’s difficult to help you determine it: 1. Check whether there are any problems with the pressure sensing tube, or if it is blocked Heating? 2. Should I pour it out several more times? 3. Check if the configuration is correct?
First, it is necessary to determine the standard pressure to ensure accuracy on-site; then check whether there was an error in the unit conversion settings within someone’s program, and this can be calculated using the measurement signal
Is it always a multiple of ten? If so, it is due to an error in the software algorithm or unit settings during DCS configuration.
