Optically addressed pressure sensors for transient gas dynamics: calibration of a preliminary design

Sharifian, S. A. and Buttsworth, D. R. (2001) Optically addressed pressure sensors for transient gas dynamics: calibration of a preliminary design. In: 14th Australasian Fluid Mechanics Conference (AFMC 2001) , 9-14 Dec 2001, Adelaide, South Australia.

Abstract

The design of pressure sensors based on interferometric
measurements of diaphragm deflection for transient gas dynamics experiments is discussed. Quasi-steady calibration results from one such sensor are presented. Results from a dynamic calibration of the same sensor are also described. Predictions of diaphragm behaviour based on a clamped circular diaphragm model are within about 30% of the results obtained from the static and dynamic calibrations. However, a strong temperature sensitivity is also apparent. Future development will focus on reducing the temperature sensitivity of the sensor in transient applications.
