Precision Vacuum Pressure Transducers at Low Cost 730574

The requirements of aerospace programs have brought about refinements in the fabrication of small precision pressure transducers in recent years. This paper describes the Gulton Model GS-1 pressure transducer, which was designed primarily for installation on automobiles. Considerations in its development were: corrosive or solvent characteristics of the pressure media commonly encountered in the automobile engine compartment; vibration and shock levels; electromagnetic interference constraints; temperature variations; calendar and cycle life; electrical power available; size and weight; mounting, including pneumatic and electrical connection; and cost. Design details for satisfying these considerations are discussed.
