What is the formula for converting a process variable (PV) to a percentage of a process variable (%PV) in a system with a 0-10 V voltage loop?
A. %PV = ((PV – PVmin)/(PVmax – PVmin))4%
B. %PV = ((PV – PVmax)/(PVmin – PVmax))20%
C. %PV = ((PV – PVmin)/(PVmax – PVmin))100%
D. %PV = ((PV – PVmax)/(PVmin – PVmax))16%
Answer:C

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