The differential pressure transducer is used in conjunction with the Trane
direct digital controller and analog electronic controller. The pressure
transducer measures the difference between the high-pressure and low-
pressure ports of the Trane flow ring. The transducer is self-adjusting to
changes in environmental temperature and humidity.
