Pressure gauges are necessary for continuous service on app lications like compressors, pumps, regulators, pipelines, storage tanks and plumbing equipment, as well as for replacements on most commercial and industrial equipment.The tube is made of a copper alloy, cases are made of steel and lenses are made of plastic. Liquid-filled pressure gauges are available in pressure ranges equal to or higher than their dry counterparts. Their casings are filled with fluid, usually glycerine, although silicone or other liquids are sometimes used. The liquid coats the internal parts and is visible on the gauge's face. The fluid fill effectively dampens system pulsation, making the gauge pointer easier to read. Likewise, humidity and moisture pose problems for dry gauges. Condensation can make a gauge difficult to read or, in some cases, can cause failure due to icing.
