Angstrom Bourdon Tube Pressure Gauges: Precision Measurement Solutions
Share
Bourdon tube pressure gauges are precision mechanical instruments that measure pressure from -1.0 to 1,000 bar using a radially formed tube with an oval cross-section that deflects proportionally to applied pressure, converting this motion into a readable dial indication through a precision movement system. Angstrom offers standard gauges with copper alloy components for general applications and stainless steel gauges (316SS) with increased corrosion resistance for aggressive environments, available in glycerin-filled or dry configurations, manufactured to EN 837-1 standards with dial sizes from 63mm to 150mm for UAE industrial applications across Dubai, Abu Dhabi, and the Emirates including oil & gas, chemical processing, water treatment, HVAC, and manufacturing operations.
What is a bourdon tube pressure gauge and how does it work?
A bourdon tube pressure gauge is a mechanical pressure measurement instrument that uses a curved, flattened tube (the bourdon tube) as its sensing element. The bourdon tube is radially formed with a precision oval cross-section, typically shaped in a C-curve at approximately 250 degrees. When pressure from the measuring medium acts on the tube's interior, the oval cross-section attempts to become circular, causing the non-clamped end of the tube to move. This controlled motion directly correlates to pressure levels and is transmitted through a precision linkage and gear system to rotate a pointer across a calibrated dial, providing an accurate visual indication of pressure. For higher pressure applications beyond 60 bar, Angstrom utilizes bourdon tubes with multiple superimposed windings (helical tubes) or spiral coils in a single plane (spiral tubes) that provide greater deflection and accuracy. This proven technology requires no external power, operates reliably in harsh UAE environments, and provides accurate pressure measurement for gaseous and liquid, non-viscous and non-crystallizing media across industrial applications in Dubai, Abu Dhabi, and the Emirates.
