<p>A differential pressure gauge comprising a base, two membranes fastened along the outer contour to the opposite sides of the base and provided with rigid discs interconnected into an integral unit through a hole in the base. The membranes are located at a certain distance from the base and form, together with the latter, a pressuretight space filled with a liquid. The rigid discs are secured to the membranes on a circular zone in which there is a chamber formed between each membrane and the disc and communicating through a channel with the pressuretight space. The gauge also comprises a means connected with the rigid discs and intended to transmit the motion of the membranes caused by the difference of pressures, and a means intended to transform this motion into an output signal.</p> |
