Answer / ahmed helmy
- instrument range is the maximum range of instrument.
- Calibration range is at which the instrument calibrated
for example
- if we have a pressure tx instrument range 0:10 bar
- we can calibrate it at any position between 0:10 bar suppose we calibrate it at 0:4 bar its mean its calibration range
is 0:4bar and instrument range 0:10 bar
Based on your case:
- line design pressure=93 bar (max pressure in the line)
- operating pressure=82 bar
so we can install pressure tx range:0 to 120 bar and calibrate the pressure tx in range from 0 to 93 bar

Answer / furqan
In addition we also can not calibrate the pressure transmitter as equal to designed line pressure
calibrate the pressure transmitter on 80 percent of designed line pressure.
