ABSTRACT:
An essentially frictionless, reliable pressure indicator capable of withstanding high pressures is disclosed. The invention includes dual opposed springs, a pair of magnetic elements, and a resilient diaphragm abutting one of the magnetic elements. Use of the resilient diaphragm permits precise control of the amount of travel necessary for the magnetic attractive forces to counteract the mechanical spring forces, increasing the accuracy of the overall device. The present structure, with its resilient diaphragm and an associated dampening aperture, is also designed to withstand transient pressures of as much as 2500 psi or more.
