A Miniature Spiral Bourdon Tube Pressure Transducer

摘要

This report gives information on the design of a miniature pressure transducer employing a spiral shaped stainless steel Bourdon tube and a deposited track potentiometer. The test results obtained from several models covering different pressure ranges are shown together with an analysis of their performance under different environmental conditions. The report also discusses the problems likely to be encountered in the design of very low pressure models and suggests a possible line of approach to further development, with particular reference to transducers having a pressure range below about 0/20 lb sq. in.
