63mm 140 PSI Boiler Pressure Gauge Bottom Brass Connection Stainless Steel Silicone Oil Filled Manometer

Product Introduction

This 63mm boiler pressure gauge is designed for medium-pressure heating and steam systems requiring stable and reliable monitoring. It combines a stainless steel case with a silicone oil filled damping system to ensure stable readings under vibration and pressure fluctuation.

With a pressure range of 0–140 PSI (0–10 bar), it is widely used in boiler units, HVAC heating systems, and industrial thermal equipment.

Technical Specifications

Applications

• Boiler pressure monitoring systems
• Heating and steam systems
• HVAC thermal control units
• Industrial heat exchange equipment
• Pump and circulation systems
• Energy equipment monitoring
• OEM heating system panels
• Fluid pressure control systems

Working Principle

The Bourdon tube inside the gauge expands when pressure increases, converting mechanical deformation into pointer movement. This allows real-time pressure reading without electrical power.

The silicone oil filling reduces internal vibration effects, improving stability in boiler and heating environments with pulsating pressure.

Industrial Usage Insight

Boiler systems often experience pressure fluctuation due to heating cycles. A liquid-filled gauge helps reduce needle oscillation and improves operator readability, especially in continuous industrial operation environments
