Product Overview

The Axial Liquid Filled Foam Guard Pressure Gauge is designed for industrial pressure monitoring applications where vibration, pulsation, and mechanical shock may affect measurement stability. Featuring a liquid-filled construction and foam guard protection design, the gauge helps maintain clear pointer visibility while reducing vibration-induced fluctuations.

Technical Specifications

Key Features

Liquid Filled Vibration Dampening

The glycerin filling reduces pointer flutter caused by compressor cycling, pump pulsation, and hydraulic shock, allowing operators to read pressure values more clearly. Liquid filling is widely used in gauges operating under adverse environments and pulsating conditions.

Axial Mount Installation

The back connection design allows front-facing display installation in control panels, machinery enclosures, and industrial equipment.

Mechanical Bourdon Tube Reliability

The Bourdon tube sensing element provides dependable pressure measurement without requiring electrical power, making it suitable for continuous industrial service.

Typical Applications

• Air compressor systems
• Water treatment equipment
• Industrial pump installations
• Pneumatic control systems
• OEM machinery manufacturing
• Pressure vessel monitoring
• Industrial process equipment
• General fluid control systems

Working Principle

The gauge operates using a Bourdon tube pressure sensing mechanism. When pressure enters the tube, the curved element tends to straighten slightly in proportion to the applied pressure.

FAQ

What is the purpose of liquid filling in a pressure gauge?

Liquid filling reduces vibration, dampens pulsation, and helps protect internal moving parts from premature wear.

What does 2000kPa equal?

2000kPa is equivalent to 20 bar or approximately 290 PSI.

Is this gauge suitable for air compressors?

Yes. The liquid-filled design is particularly suitable for compressor systems where pressure pulsation can affect standard dry gauges.

Can the gauge be used for water pump systems?

Yes. It is commonly used for pump discharge monitoring, booster pump systems, and industrial water treatment equipment.
