Model 2-40 High Pressure Potentiometric Pressure Transducer BEI Edcliff Instruments Division The Model 2-40 Pressure Transducer is designed for use in a variety of applications where accurate, reliable, high-pressure measurement is required. The 2-40 Pressure Transducer ultilizes a Ni-Span-C helical bourdon tube to drive a contact wiper across a precisely wound resistance element creating a voltage divider that can provide an electrical output directly proportional to the pressure applied. The 2-40 is designed to survive and operate in aviation, spacecraft and industrial environments of high shock, vibration, rough handling and hostile fluids. The 2-40 is a rugged, mature pressure transducer that is currently in service in a variety of business, commuter, and pleasure aircraft, and commercial research spacecraft as well as automated assembly control systems, downhole oil well, water filtration and treatment systems. The 2-40 has also served as the basis for a variety of unique custom configurations requiring special mounting and installation, electrical connections and pressure fittings. Please contact the factory for unique applications.
