A stainless steel pressure gauge is typically used to monitor pressure in industrial settings. Liquids and gasses both have to be kept under a certain amount of pressure in order for them to perform as expected. The only way to know for sure that the liquids and gases are at the correct amount of pressure is with a pressure gauge attached to either the closed pipes or enclosed tanks or vats. As for stainless steel pressure gauges, they have some benefits over copper or iron gauges.
Stainless Steel Does Not Rust or Corrode
Copper can corrode; you can see that in old pennies that have darkened or gained a greenish patina. Iron rusts. Everything from old cars to iron artifacts are loaded with rust. Both cannot and do not last in an industrial environment because of the nature of the chemicals under pressure, the temperatures within the factory or plant, and the humidity surrounding these metals.
Stainless steel, on the other hand, does not rust or corrode. It maintains itself under the given conditions, and it lasts a very long time. This is vital to the applications required for gauges.
Stainless Steel Gauges Have Wetted Parts That Last and Are More Compatible
The phrase, "wetted parts," refers to the parts of a gauge that comes into contact with the liquid or gas that is measured by the gauge. It is extremely important that the wetted parts be compatible with both the material of the gauge and with the substance being gauged, or measured. In the case of stainless steel, the material of the gauge is already fit and perfect for the job, the environment, and the pressure it faces. Its wetted parts are equally compatible with almost every liquid or gas, except the most highly corrosive acids or products like liquid nitrogen, where pressure and extreme cold or extreme heat could liquefy, or freeze and explode, the gauge.
Magnetism Does Not Affect a Stainless Steel Gauge's Internal Components
Because of the potential for magnetism to affect the readings on a gauge, stainless steel gauges are typically fashioned out of alloys that are not magnetic. This is an important factor if you are attempting to measure any substance or matter that is, or may be, magnetic in nature. You get a much more accurate reading on these gauges because the magnetism of the gas or liquid is not creating havoc with the gauge's ability to provide readings.
