Answer Posted / dhanasekaran c
Depends upon the valve. Pneumatic calibrator for 0.2to
1.00kg/cm2 Valve.For Electronic positioner( 4-20ma) We can
use Loop calibrator. For Smart type of positioner fixed
valves smart calibrator 275 or 375 or 475(latest) must be
used. Field bus MC5 hand held calibrator can be used.
