Vibro-Meter's oil and fuel pressure transmitters are used on many commercial aircraft manufactured in the United States. The transmitters utilize variable reluctance technology, and are designed for mounting directly onto the engines. The operating voltage is 26-28 VAC 400 Hz at temperatures up to 450ºF. They are qualified to TSO-C47, measure pressures between 60 and 400 psi, and weigh approximately one pound. Our transmitters will interface with various displays, from the older 2-inch round variable reluctance indicators, to the newer glass cockpit displays.
