Gauges

Gauges are used to measure different types of objects having various sizes, shapes, and thicknesses, the gap in space, diameter of materials, or pressure of the flow. Specific types of gauges are used to measure each parameter. Gauges measure positive system pressure starting at zero, usually in psi units. Vacuum gauges measure vacuum, or negative, system pressure, usually in the imperial unit inches of Mercury (in Hg).

Compound pressure and vacuum gauges measure both positive and negative system pressure. Gauges are used to monitor and control pressure – which is often a necessity in industrial processing.
