1.what is the role of proportional comtroller in pid
controller?2.How do u calibrate the control valve?
Answer Posted / prashant
proportional function is take place an action to maintain
the pv proportionaly to error in p.v . but an offset error
is sustained , that will be reduced by integral funtional.
calbration of control valve :::
1. check the pneumatic pressure of regulator
2. give the 4-20 ma to check the strock of c/v
3. if storck is not achieving then adjusted by zero
