ABSTRACT:
A device for transmitting the displacement of a pressure-responsive element is situated in pressure space. The device is provided with a base hermetically held to a shell which confines the pressure space, and has a hole covered by the diaphragm hermetically held along the external perimeter of the hole. The device incorporates also a force-bar passing at the center of the diaphragm, with the end of the force-bar protruding inside the shell being adapted to interact with the pressure-responsive element, while its end extending outwards from the shell serves essentially as the output of the device; the output of the force-bar carries a cross-bar interconnected therewith through a resilient member to which, secured with their one ends, are two struts whose other ends are secured to the base, with the axes of the struts being approximately in the same plane with the axis of the diaphragm; provision is also made for a means adapted to vary the position of the axes of the struts, with such means being constructed as adjustable stops provided in the cross-bar and adapted to interact with the force-bar.
