Meaning and Definition
A mechanical pressure gauge using a curved, flattened tube (Bourdon tube) that straightens under pressure, moving a pointer via a linkage.
A widely used, robust type of analogue pressure measuring instrument found in industrial, automotive, and HVAC systems. Its principle relies on the elastic deformation of a C-shaped or coiled tube.

FAQ
Frequently Asked Questions
No. A manometer typically measures pressure by balancing it against a column of liquid (e.g., mercury, water). A bourdon gauge is a type of mechanical, elastic-element pressure gauge. All bourdon gauges are pressure gauges, but not all pressure gauges (like manometers) are bourdon gauges.
It is an eponym, derived from the surname of the French inventor Eugène Bourdon who patented the design in 1849. Proper nouns are capitalized in English.
Yes, extensively. They are valued in many industrial, automotive, and HVAC applications for their simplicity, robustness, lack of need for external power, and cost-effectiveness, especially where a direct local reading is sufficient.
Key advantages include mechanical simplicity, durability, relatively low cost, no requirement for an electrical power supply, and good accuracy for many applications. They are also less susceptible to electrical interference.

Learning
Memory Aids
Mnemonic
Think of a curved 'BOURDON' tube straightening like a 'BOW' being unstrung to show the pressure.
Conceptual Metaphor
PRESSURE IS A FORCE THAT STRAIGHTENS (The invisible force of pressure is made visible by the physical straightening of the tube).
