The gauge uses stainless steel for key internal parts like the Bourdon tube, socket, case, and movement to resist corrosion from both media and the environment. Technicians weld the wetted parts using argon arc welding and inspect each unit for proof pressure and airtightness under strict quality control.
To ensure optimal performance, select a pressure range where your typical operating pressure falls within 30–65% of the full scale. Also, confirm that the wetted materials are compatible with the gas or liquid being measured.
