There are many pressure gauges however the bourdon gauge is probably one of the most common. Bourdon tube pressure gauges are the most frequently used mechanical pressure measuring instruments.

Analogue pressure measurement gauges employ bourdon tubes photo credit.
What does a bourdon gauge measure. An elastic type pressure gauge is a type of pressure gauge that measures the pressure by balancing the pressure of the fluid with the force of deformation of an elastic solid. Their pressure element is often referred to as a bourdon tube. The bourdon tube invented by eugene bourdon 1808 84 fig 3 10 and the diaphragm fig 3 11 are widely employed for this type of pressure gauge.
A bourdon tube is used to measure pressure in a system giving the user visual indication of the pressure level ensuring the amount of pressure doesn t exceed the maximum level or stoop too low. There are many pressure gauges however the bourdon gauge is probably one of the most common. It is relatively cheap and is commonly used for measuring the gauge pressure of both gaseous and liquid fluids.
The bourdon tube is also an elastic element type of pressure transducer. It is named after its inventor eugene bourdon who created and patented the design. Ensuper shutterstock a bourdon tube is the working mechanism for any analogue pressure measurement device.
A bourdon tube is the working mechanism of analogue pressure measurement devices and is based on the principle of elasticity. The french engineer eugène bourdon made use of this functional principle in the middle of the 19th century. A bourdon tube is used to measure pressure in a system giving the user visual indication of the pressure level ensuring the amount of pressure doesn t exceed the maximum level or stoop too low.
While sophisticated measuring tools employ lcd screens to display measurement figures accurately up to several decimal places the humble analogue gauge remains defiantly present in almost all pressure measurement devices. It consists of a specially shaped piece of oval section flexible metal tube that is fixed at one end and free to move at the other end. Bourdon gauges are used to measure pressure in simple devices such as household barometers as well as in specialized devices used in industrial mechanical and medical settings.
