What is the purpose of the pressure transducer as shown in the illustration? Illustration GS-RA-17 Illustration GS-RA-17: the U.S. Coast Guard has not released this illustration.

Correct Answer: Option A — it senses compressor suction pressure and controls the quench valve

In screw or specialized marine compressor configurations, the suction pressure transducer monitors incoming vapor conditions and provides critical feedback signals to modulate the liquid injection or quench valve, protecting internal components from excessive discharge temperatures.
