100mm All Stainless Steel Liquid Filled Pressure Gauge Shockproof Stainless Steel Pressure Gauge for Industrial Hydraulic Systems

Our 100mm all stainless steel shockproof pressure gauge is a widely used industrial pressure measuring instrument. It adopts a fully stainless steel structure and liquid-filled internal design, which effectively dampens vibration and pulsating pressure in working conditions. The large 100mm dial provides clear, easy-to-read pressure values from a distance. A dual scale (MPa / psi) is printed on the dial to meet international reading habits. With excellent rust-proof and corrosion-resistant performance, it works reliably under humid, corrosive and vibrating environments, making it ideal for long-term continuous on-site monitoring.

• Dial size: 100 mm — large dial for easy reading
• Full stainless steel construction: case, socket and wetted parts are all stainless steel
• Liquid-filled, vibration-resistant design — anti-shock and anti-pulsation
• Dual scale: MPa and psi, convenient for global users
• Accuracy Class 1.6 for stable and repeatable measurement
• Good corrosion resistance, suitable for damp and mildly corrosive media
• Robust structure with long service life and low maintenance
• Multiple pressure ranges and thread sizes (BSP / NPT) customizable
• Optional bayonet bezel for easy opening and maintenance

The pressure of the measured medium acts on the internal bourdon tube. The bourdon tube deforms under pressure, and the movement transfers this deformation to the pointer, showing the real-time pressure value on the dial. The glycerin filling liquid inside absorbs vibration and pressure fluctuation, preventing pointer jitter and protecting the internal movement.

Suitable for equipment and pipelines with vibration or pressure pulsation:

• Hydraulic systems and hydraulic machinery
• Pneumatic compressor stations
• Water treatment and water supply pipelines
• Oil, gas and fuel transmission systems
• General industrial machinery, pumps and valves
• Marine equipment, mining equipment and chemical auxiliary pipelines
• Refrigeration and HVAC systems

1. Shockproof liquid-filled design — Glycerin filling suppresses pointer shaking caused by vibration and pressure surges, keeping readings stable.
2. Full stainless steel anti-corrosion build — Compared with brass socket gauges, it resists rust and mild corrosion, fitting more complex working environments.
3. 100mm large dial for clear reading — Operators can read pressure data quickly, even from a distance on the production site.
4. Global dual scale design — MPa and psi dual-unit dial, directly usable for overseas projects without conversion.
5. Flexible customization support — We support custom pressure range, thread standard, dial logo and bayonet structure.
6. Cost-effective industrial instrument — Consistent quality, competitive price and stable supply for bulk industrial orders.
