2. Sample Practice Question
Practice Question: A 3-15 psi pneumatic control valve with an air-to-close (fail-open) actuator is fitted with an I/P transducer receiving a 4-20 mA signal. When the input current is 12 mA, what is the output air pressure and valve position?
A) 9 psi, 50% open
B) 6 psi, 25% open
C) 9 psi, 100% open
D) 12 psi, 50% open
Correct Answer: A) 12 mA is 50% of the 4-20 mA range, producing 9 psi (midpoint of 3-15 psi). For a fail-open valve (air-to-close), 50% pressure positions the valve exactly 50% open.
