Mm. Nayak et al., SPUTTERED THIN-FILM STRAIN-GAUGES FOR DIFFERENTIAL PRESSURE MEASUREMENT, IEEE transactions on instrumentation and measurement, 45(1), 1996, pp. 335-339
A differential pressure transducer with sputtered gold films as strain
gauges has been designed and fabricated. The construction details of
the sensing element assembly are given. The details of the strain gaug
e film configuration employed and the thin-film deposition process are
also presented. Information on the output characteristics of the diff
erential pressure transducer such as effect of pressure cycles on outp
ut, thermal stability, bidirectional calibration results obtained and
individual gauge stability is reported.
