STAINLESS STEEL PRESSURE GAUGE | PM-E.VN

What Is a Stainless Steel Pressure Gauge?

A Stainless Steel Pressure Gauge is a mechanical instrument used to measure and display pressure in compressed air systems, water systems, steam lines, and industrial fluid applications.

The key feature of this type of gauge is that its housing and/or major components are made of stainless steel (typically 304 or 316), providing excellent corrosion resistance and durability in harsh environments such as chemicals, outdoor installations, or humid conditions.

The device operates based on the Bourdon tube principle, ensuring accurate pressure measurement and direct visual indication on the dial.

Key Features of Stainless Steel Pressure Gauges

Stainless steel pressure gauges are widely used due to the following advantages:

• Excellent corrosion resistance
• High durability in industrial environments
• Stable operation under vibration conditions
• High accuracy and easy readability
• Suitable for various media (water, air, steam, oil)
• Complies with EN 837-1 standards
• Wide range of pressure ranges and sizes

This type of gauge is ideal for applications requiring long-term reliability in harsh operating conditions.

Construction of a Stainless Steel Pressure Gauge

A stainless steel pressure gauge consists of the following main components:

Stainless Steel Case

Made of 304 or 316 stainless steel, providing excellent corrosion resistance and durability.

Dial Face

Clearly marked scale for easy and fast pressure reading.

Pointer Needle

Indicates real-time pressure values.

Movement Mechanism

Transfers motion from the Bourdon tube to the pointer.

Bourdon Tube

The main sensing element that converts pressure into mechanical movement.

Protective Glass

Tempered glass that protects the internal components from dust and impact.

Working Principle

When pressure is applied to the system, the process fluid enters the Bourdon tube inside the gauge.

The Bourdon tube deforms proportionally to pressure changes and transfers this movement to the mechanical linkage system.

This mechanism rotates the pointer, displaying the corresponding pressure value on the dial.

Thanks to its stainless steel housing, the gauge can operate reliably in vibrating, humid, or mildly corrosive environments.

Applications of Stainless Steel Pressure Gauges

Stainless steel pressure gauges are widely used in:

• Water treatment systems
• Chemical industries
• Oil and gas industries
• Industrial compressed air systems
• Boilers and steam systems
• Food and beverage industry
