ABSTRACT:
A differential pressure sensor has a sensing diaphragm mounted in a body. The curvature of the diaphragm is representative of differential pressure across the diaphragm. Monochromatic light is direct from a source at the diaphragm to set up interference fringes which have varying spacings representative of the curvature, in the manner of Newton's rings. The fringes and their spacings are monitored and a computer calculates therefrom the curvature of the diaphragm and thence the pressure difference.
