Construction
An elastic transducer, which is a bourdon tube that is fixed and open at one end to accept the pressure to be measured, is the major component of this instrument. The bourdon tube’s other end is open and closed. The bourdon tube has an oval cross-section. The bourdon tube has been bent into the shape of a circular arc. An adjustable link is joined ...
Working Principle
The working of a Bourdon pressure gauge is less complex and can be easily understood. The pressure to be measured is connected to the bourdon tube’s fixed open end. The exerted pressure acts on the bourdon tube’s inner walls. The cross-section of the bourdon tube tends to transform from elliptical to circular as a result of the applied pressure. Th...
Advantages and Disadvantages of A Bourdon Pressure Gauge
Advantages:

What is Bourdon effect?

Bourdon Effect is associated with the pressure elongation of the piping and pipeline systems. In piping and pipeline systems, elbows or bends are frequently used for changing the direction of the pipe. The behavior of elbows and bends subjected to internal pressure is quite different as compared to a straight pipe.

How does a Bourdon gauge work?

A.C. Fischer-Cripps, in Newnes Interfacing Companion, 2002 The Bourdon gauge consists of a tube bent into a coil or an arc. As the pressure in the tube increases, the coil unwinds. A pointer connected to the end of the tube can be attached to a lever and a pointer calibrated to indicate pressure.

What are Bourdon-type pressure devices?

Bourdon-type pressure devices are used to detect pressure in industrial installations and pressure monitoring systems. Bourdon tubes are manufactured in various engineering shapes like circular-C, helix, and spiral, to serve the use of this tube in terms of positioning and accuracy.

How does pressure affect the cross section of a bourdon tube?

The cross-section of the bourdon tube tends to transform from elliptical to circular as a result of the applied pressure. This tends to straighten the bourdon tube, causing the free end of the bourdon tube to be displaced. The applied pressure is proportional to the displacement of the free-closed end of the bourdon tube.
