Stainless Steel Liquid-Filled Pressure Gauge, 4 Inch

Product Type: Stainless Steel Liquid-Filled Pressure Gauge
Case & Wetted Material: Full stainless steel construction (case, Bourdon tube, socket) for corrosion resistance and durability
Filling Medium: Glycerin-filled movement to dampen needle vibration and pulsation, ensuring stable, accurate readings under dynamic conditions
Dial Size: 100mm (4 Inch) white dial with high-contrast black markings
Measurement Range: 0 - 3000 psi
Accuracy Class: 1.6 (±1.6% of full scale, per JB/T standard)

Bottom-mount version: 1/4 Inch or 1/2 Inch NPT male threaded, bottom entry
Back-mount version: rear-lower threaded connection with panel mounting bracket/lug for flush installation
Movement: Bourdon tube type, suitable for general industrial pressure monitoring
Protection Level: Sealed case construction suitable for outdoor/industrial environments (liquid fill also provides added moisture and vibration protection)

Stable, Vibration-Resistant Readings: The glycerin fill absorbs pulsation and mechanical vibration from pumps, compressors, and piping systems, extending gauge life and improving readability.

All-Stainless-Steel Durability: Full stainless steel case and internals resist corrosion in humid, chemical, or outdoor environments - ideal for oilfield, EPC, and industrial piping applications.

Flexible Mounting Options: Available in bottom-mount and back-mount (panel bracket) configurations to suit different installation layouts.

Wide Pressure Range with Reliable Accuracy: Covers 0–3000 psi at a solid 1.6 accuracy class, meeting general industrial monitoring requirements.

Suitable for pressure monitoring on pipelines, pumps, compressors, valves, and process skids in oil & gas, petrochemical, EPC, and general industrial piping systems - particularly where vibration, pulsation, or outdoor exposure would affect a standard dry gauge.
