Product Description
A stainless steel pressure gauge is a type of pressure measuring instrument that is designed with stainless steel components particularly for the parts exposed to the process fluid or environment Heres a detailed overview of its construction features and applications
Construction
1 Case and Internals
Stainless Steel Case The outer casing of the gauge is typically made from stainless steel This provides durability and resistance to corrosion making it suitable for a wide range of industrial and process environments
Stainless Steel Internals Components such as the bourdon tube the mechanical element that converts pressure into movement and other internal parts exposed to the pressure medium are also made from stainless steel This ensures compatibility with various fluids and gases without risk of contamination or degradation
2 Pressure Sensing Mechanism
Bourdon Tube This is the most common type of pressure sensing mechanism used in mechanical pressure gauges It is a curved tube that tends to straighten under pressure which is then mechanically linked to a pointer on a dial to indicate pressure
Movement and Pointer The movement of the bourdon tube due to pressure changes is translated into a rotational movement of a pointer on a dial face calibrated in pressure units psi bar kPa etc
3 Dial and Scale
Scale Calibration The gauge is calibrated to display pressure readings accurately across a specified range Different scales and units can be used depending on the application and region
Visibility The dial typically has clear markings and a pointer that moves smoothly over the scale allowing for easy reading of pressure values
