To control the turbocharger, the APC monitors the engine's RPM and inlet manifold pressure via a pressure transducer, and uses these inputs to control a solenoid valve that trims the rate of rise of pressure as well as the maximum pressure by directing boost pressure to the turbocharger's pneumatic wastegate actuator.

A computer-controlled mechanism inflates the balloon with helium from a cylinder during diastole, usually linked to either an electrocardiogram ( ECG ) or a pressure transducer at the distal tip of the catheter; some IABPs, such as the Datascope System 98XT, allow asynchronous counterpulsation at a set rate, though this setting is rarely used.

A U . S . Air Force Test Pilot School glider carrying a microphone on the left wingtip, and a pressure transducer on the side of the fuselage, flew at a lower altitude of 10, 000 feet under the path of the F-5E, which flew at 32, 000 feet, to record sonic booms in the air.

Beginning in 1995 the company introduced a series of vacuum tube microphones with transformerless output circuitry : the multi-pattern M 149 Tube, the cardioid M 147 Tube, and the omnidirectional M 150 Tube ( based on the classic M 50 design, with the pressure transducer mounted in the surface of a sphere inside the capsule head ).

Studies of recording sniffing in the context of odor-guided tasks involve implanting intranasal temperature and pressure sensors into the nasal cavity of animals and either measuring odor-orienting responses ( fast sniffing ) Alternatively, animals can be conditioned to insert their snouts into an air-tight chamber with a pressure transducer embedded within to access nasal transients, while simultaneously odors are presented to measure responses while nose-poking.
