Specialty Gages For All Processes

Corrosion-Resistant Pressure Gauges
ServoCon ALPHA offers models with features having ±1% of span accuracy and utilize stainless steel cases. These heavy duty 2”, 2-1/2” and 3-1/2” pressure gauges are specifically designed to withstand the corrosive atmospheres, such as salt air, sour gas, and other industrial gases. These gauges are also used in specialty gauge regulators and gas cabinets and many other applications. Our models feature all internal wetted surfaces of 316L, making these gauges ideally suited for use with corrosive process media.

Models are available in pressure ranges from 30” Hg VAC-0 psi to 0-3000 psi. These precision gages incorporate rugged case construction with rear pressure relief, and a seamless Bourdon tube with welded joints for heavy duty service. There is a unit available in a version for the semiconductor industry.
