The “silvery”/”black” interface is easy to see from several feet away. Reflex gauges provide an excellent way to measure clear, or difficult to see fluids. When light strikes the glass where no liquid is present, the prisms reflect the light directly out of the gauge. When light strikes the portion of the glass covered by a liquid, the light is reflected from the back of the chamber. This piece of glass is flat on the outside, and has a series of prisms on the inside, facing the process fluid. Reflex gauges have a single piece of glass, mounted on one side of the chamber. Bolts/Studs/Nuts: Provides a uniform compression load to the gauge for pressure sealing.For a given gauge, the gasket and cushion are normally the same material. Gasket/Cushion: Provides for a seal between the chamber and glass (gasket), and protects the glass from mechanical stresses from the cover (cushion).The cushion seat is recessed for lateral support and easy positioning.
