ABSTRACT:
An improved arrangement for responding to reversal in the sense of the ratio between two pressures. In a housing there is located a generally cup-shaped indicator element of resilient, air impermeable material including a slack diaphragm having a central area of augmented visibility and an integral tongue projecting obliquely therefrom. The diaphragm is self-biased in either of two positions, in one of which the tongue conceals the central area, and in the other of which the tongue exposes the area. Pressures to be compared are applied on opposite sides of the diaphragm, and an observation window is provided.
