Bourdon Tube Pressure Gauge

Pressure Gauges

The Bourdon Tube Pressure Gauge is a classic and highly reliable mechanical instrument designed for measuring the pressure of liquid and gaseous media. Engineered to withstand harsh industrial environments, this gauge features a robust 304 stainless steel housing and IP65 protection. It is specifically designed for corrosive locations, utilizing high-quality 316L or 304 stainless steel for the internal Bourdon tube measuring element. With a wide variety of dial diameters and pressure ranges reaching up to 100MPa, it provides accurate and stable readings for critical process monitoring in extreme temperatures up to +150°C.

Description

Overview of Bourdon Tube Pressure Gauge

The Bourdon Tube Pressure Gauge is the industry standard for reliable, local pressure indication without the need for external power.

What is it? It is a mechanical pressure measurement device that utilizes a curved, hollow tube (the Bourdon tube). As internal pressure increases, the tube tends to straighten. This minute movement is transmitted via a high-precision gear movement to the pointer, indicating the exact pressure on the dial.
Main Application Field: This gauge is ideal for corrosive industrial environments, including petroleum, chemical plants, power stations, offshore operations, mining, environmental engineering, and general process technology.
Key CharacteristicsBuilt for durability, the gauge features an all-stainless steel construction. It is capable of handling medium temperatures up to +150°C and is available in six different dial sizes to ensure readability in any installation space.

Features of Bourdon Tube Pressure Gauge

Extreme Corrosion Resistance: The case is made of 304 stainless steel, while the wetted parts (Bourdon tube and connection) are available in 316L or 304 stainless steel, ensuring longevity in aggressive chemical areas.
Wide Pressure Spectrum: Capable of measuring everything from vacuum (-0.1MPa) up to extremely high pressures (100MPa).
Versatile Dial Sizes: Offers a full range of diameters (40mm to 250mm) to fit small equipment or large-scale control panels.
High Temperature Tolerance: Designed to operate safely with medium temperatures up to +150°C.
Environmental Protection: Rated IP65, protecting the internal movement from dust, rain, and water splashes.
Flexible Mounting: Available in both radial (bottom) and axial (back) connection types to suit different piping layouts.

Applications of Bourdon Tube Pressure Gauge

Oil & Gas / Offshore: Monitoring wellhead pressures and pipeline status in salt-mist and corrosive environments.
Chemical & Petrochemical: Measuring pressures of corrosive reagents and process gases.
Power Generation: Monitoring steam, water, and lubricant pressures in turbine and boiler systems.
Mining & Heavy Industry: Rugged enough for the high-vibration and dusty conditions of mining equipment.
Environmental Engineering: Used in water treatment and waste processing facilities.

Price of Bourdon Tube Pressure Gauge

The price of the Bourdon Tube Pressure Gauge varies based on the dial diameter (e.g., 60mm vs. 150mm), the required accuracy class, and the pressure range.
