LOW PRESSURE MEASUREMENT TECHNIQUES.

Abstract

This project was initiated to develop four prototype pressure transducers in the range of 0.0 to 0.1 psia for Wright-Patterson AFB. The design selected makes use of a convoluted diaphragm force collector to drive a cantilever beam. A semiconductor strain gage bridge bonded to the beam converts the force to an electrical signal which is amplified to provide a 0 to 5V dc output. The results presented demonstrate achievement of essentially all requirements, save high-temperature transient performance. It is apparent from the results of this project that an accurate 0.0 to 0.1 psia transducer of low weight and reasonably high natural frequency can be produced. Achievement of higher operating temperature and natural frequency is possible.
