Meaning and Definition
A mechanical pressure measuring instrument that uses a curved, flattened tube (the Bourdon tube) that straightens under pressure, with the movement transmitted to a pointer on a dial.
A widely used type of analogue gauge for measuring fluid or gas pressure in industrial, automotive, and HVAC systems. The term can also refer metonymically to the pressure reading itself.
Dialectal Variation
British vs American Usage
Differences
Spelling and terminology largely identical. 'Gauge' is the standard spelling in both, though American engineering texts may occasionally use 'gage' in specific contexts, but not typically for this instrument.
Connotations
No significant connotative difference. It denotes a reliable, robust, traditional measuring instrument in both varieties.
Frequency
Equally low-frequency and specialized in both regions, confined to engineering, maintenance, and technical manuals.

FAQ
Frequently Asked Questions
It is a purely mechanical, analogue instrument. The movement of the tube physically moves a pointer across a dial.
It can measure the pressure of liquids, gases, and vapours, provided the tube material is compatible with the media (e.g., stainless steel for corrosive fluids).
It was invented by the French engineer Eugène Bourdon in 1849.
It is valued for its simplicity, reliability without a power source, durability in harsh environments (high temperature, vibration), and ease of interpretation at a glance.
A mechanical pressure measuring instrument that uses a curved, flattened tube (the Bourdon tube) that straightens under pressure, with the movement transmitted to a pointer on a dial.
Bourdon-tube gauge is usually technical/industrial in register.
