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
Compressed air systems
Boilers and pressure vessels
HVAC systems
Food processing plants
Light chemical industries
Mechanical engineering systems
Industrial production lines

The device is used to:

Monitor system pressure
Detect leaks
Prevent overpressure damage
Ensure safe system operation

What Is a Flame Arrester? Why Is It Necessary?

02/07/2026

In storage and transfer systems handling flammable media such as petroleum products, chemicals, solvents, LPG, LNG, and other hazardous gases, one of the most critical safety risks is flashback ignition through piping or vent lines. A single ignition source at the vent outlet or in the surrounding environment can allow flame propagation back into the storage tank, potentially resulting in catastrophic fire or explosion.

What Types of Valves and Equipment Are Commonly Installed with a Flame Arrester?

02/07/2026

A Flame Arrester is typically not installed as a standalone device. Instead, it is commonly used in combination with safety devices such as Breather Valves, Emergency Vent Valves, and Check Valves. Each component serves a specific function, including pressure regulation, emergency pressure relief, or reverse flow prevention. Depending on the application—such as petroleum storage tanks, gas handling systems, or welding and cutting equipment—the combination of these devices will vary to provide comprehensive safety and reliable system protection.

When Is a Tank Breather Valve Required?

02/07/2026

A breather valve (Pressure Vacuum Relief Valve – PVRV) is a critical safety device for oil and chemical storage tanks. It helps balance pressure and vacuum conditions during filling, emptying, and temperature changes. This article provides a detailed analysis of five mandatory cases for installing a breather valve according to the API 2000 standard, helping engineers select the correct equipment, improve operational safety, and reduce product vapor losses.
