OMEGA’s PGM series gauges are suitable for corrosive environments in chemical, petro-chemical, refining, power, marine and food and pharmaceutical processing applications. The PGM series comes in a 63 mm (2½') or 100 mm (4') case, features all stainless steel construction and is environmentally protected to IP65.
The PGM series can also be liquid filled in the field. Liquid filled pressure gauges provide users with a number of advantages in certain applications. They are ideally suited for uses on equipment where excessive vibration and pulsation are encountered such as pumps, compressors and machine tools etc. The liquid fill minimizes the effect of these severe environments, protects the gauge internals and provides continuous lubrication in the mechanism, all adding up to extended service life. Liquid filling provides greater protection of the gauge internals from corrosive atmospheres. Gauges can be filled with a variety of fluids including glycerin, mineral oil and silicone oil.
