What is the formula for converting a percentage of a process variable (%PV) to a process variable (PV) in a system with a 0-10 V voltage loop?
A. PV = (%PV/100)(PVmax – PVmin) + PVmin
B. PV = (%PV/10)(PVmin – PVmax) + PVmin
C. PV = (%PV/5)(PVmax – PVmin) – PVmin
D. PV = (%PV/1)(PVmin – PVmax) – PVmin
Answer:A

Explanation: To convert a percentage of a process variable (%PV) to a process variable (PV) in a system with a 0-10 V voltage loop, use the formula PV = (%PV/100)*(PVmax – PVmin) + PVmin
