Product Overview

The YNBF all stainless steel liquid filled pressure gauge is designed for industrial pressure measurement in high vibration and corrosive environments. It adopts a Bourdon tube sensing element combined with a stainless steel sealed housing and liquid filling (glycerin or silicone oil) for damping.

Technical Specifications

Application Areas

• Hydraulic system pressure monitoring
• Pump and booster station systems
• Compressor pressure control systems
• Chemical processing and corrosive fluid systems
• Oil and gas pipeline auxiliary monitoring
• Water treatment and RO systems
• HVAC and industrial automation equipment
• Marine and offshore engineering systems

Product Advantages

Vibration Dampening Design

Liquid filling (glycerin or silicone oil) reduces pointer fluctuation under pulsation pressure and mechanical vibration.

Corrosion Resistant Structure

stainless steel wetted parts ensure compatibility with water, oil, gas, and mild chemical media.

Stable Mechanical Measurement

Bourdon tube mechanical system provides continuous analog pressure indication without external power supply.

Extended Service Life

Sealed case design reduces condensation and internal contamination in dynamic industrial environments.

Working Principle

The Bourdon tube deforms under pressure and transmits mechanical movement through a gear mechanism to the pointer. The liquid-filled chamber dampens vibration energy and improves reading stability under fluctuating pressure conditions.

FAQ

What is the difference between glycerin and silicone oil fill?

Glycerin is widely used for general industrial environments, while silicone oil performs better under extreme temperature variations.

Can this gauge be used in high vibration systems?

Yes, it is designed specifically for pump systems, compressors, and machinery with pulsation and vibration conditions.

Is this gauge suitable for corrosive media?

Yes, stainless steel wetted parts provide corrosion resistance for mild chemical and industrial fluids.
