HSG Series Stainless Steel Liquid-Filled Pressure Gauges
Engineering Overview & Structural Features
The HSG Series Stainless Steel Liquid-Filled Pressure Gauges provide precision pressure monitoring across demanding high-pressure hydraulic pumps, cylinders, bolting tools, and proof-load testing circuits. Engineered with corrosion-resistant AISI 304 stainless steel housings and liquid glycerine filling, HSG gauges effectively dampen mechanical vibration and rapid pressure surges for steady, shock-resistant needle readings. Calibrated with Class 1.0 (±1.0%) full-scale accuracy and clear dual-graduated MPa/Bar and PSI scales, they ensure rapid and dependable field measurement under severe conditions.
Liquid-Filled Seismic Damping
Internal glycerine liquid filling lubricates the Bourdon tube movement, protecting delicate internal gears from continuous pressure pulses and heavy field mechanical vibrations.
Corrosion-Resistant Stainless Steel
Constructed with rugged AISI 304 stainless steel case and bezel ring with integral rear safety blow-out relief disc, ensuring exceptional resistance against saline spray and aggressive industrial atmospheres.
Dual-Scale MPa & PSI Dial
Crisp white dial face features high-contrast dual-scale graduations calibrated in both metric (MPa/Bar) and imperial (PSI), enabling instantaneous reading without manual unit conversion.
Class 1.0 Full-Scale Accuracy
Precision-calibrated Bourdon tube movement delivers certified Class 1.0 full-scale accuracy (±1.0%), providing reliable verification for critical load-holding and bolt-tensioning pressures.
Fast Installation & Adaptor Fit
Standard bottom-mount 1/4" NPT, 1/2" NPT, and G-1/2" threads mate directly with HydraStark HGA Series gauge adaptors, allowing fast in-line installation on pumps and valve manifolds.
OEM Cross-Reference & Dimensional Interchangeability
Stainless steel liquid-filled pressure gauges rated for 700 to 1,600 Bar (10,000 to 23,000 PSI), engineered for continuous hydraulic monitoring, pulsation damping, and proof-load testing with Class 1.0 (±1.0%) precision across 63.5 mm and 101.6 mm dial diameters. 0 - 1600 Bar Liquid-Filled Gauges.
