BRASS CONNECTION PRESSURE GAUGE | PM-E.VN

What Is a Brass Connection Pressure Gauge?

A Brass Connection Pressure Gauge is a mechanical instrument used to measure pressure in air, gas, steam, or liquid systems in industrial applications.

The key feature of this type of gauge is its brass (copper alloy) connection at the inlet, which improves sealing performance, corrosion resistance, and mechanical durability in demanding environments.

The instrument operates based on the Bourdon tube principle, providing accurate and stable pressure readings directly on the dial.

Common pressure units include:

• Bar
• PSI
• kg/cm²
• MPa

Key Features of Brass Connection Pressure Gauges

Brass connection pressure gauges are widely used due to the following advantages:

• High durability and long service life
• Excellent corrosion resistance at the connection point
• Stable operation under vibration conditions
• High measurement accuracy and easy readability
• Wide range of sizes and pressure ranges
• Easy installation and replacement
• Compatible with water, air, steam, and light industrial fluids

The device meets EN 837-1 standards, ensuring reliability and safe operation in industrial environments.

Construction of a Brass Connection Pressure Gauge

A brass connection pressure gauge consists of the following main components:

Gauge Case

Usually made of stainless steel 304 or 316, providing strong protection against corrosion and harsh environments.

Dial Face

Clear graduated scale for easy and accurate pressure reading.

Pointer Needle

Indicates real-time pressure values.

Mechanical Movement

Transfers motion from the Bourdon tube to the pointer.

Brass Connection (Inlet Fitting)

The key feature of this gauge, providing:

• Strong sealing performance
• Corrosion resistance
• High pressure durability
• Stable connection to piping systems

Protective Lens

Made of tempered glass for impact resistance and clear visibility.

Bourdon Tube

The main sensing element that converts pressure into mechanical motion.

Working Principle

When pressure increases inside the system, the fluid or gas acts on the Bourdon tube inside the gauge.

The Bourdon tube deforms proportionally to the pressure and transmits this movement to the mechanical system.

This motion rotates the pointer across the dial, displaying the measured pressure value in real time.

Thanks to the brass connection design, the gauge maintains stable performance even in vibrating or high-pressure environments.

Applications of Brass Connection Pressure Gauges

Brass connection pressure gauges are widely used in:

• Water supply systems
• Industrial pumps
