Variable reluctance (VR) pressure sensing technology allows for a number of design features not available in many of the more common sensing techniques. Design features such as a large metallic diaphragm, relatively large diaphragm movement, magnetic sensing circuitry, high over-pressure capability, and all-welded construction (no brittle adhesives or crystals) achieve high accuracy over long term application, in very demanding environments. The VR vacuum sensor designed for the International Space Station (ISS) is a good example of where this type of sensing technique can be used where many others cannot.
