WORKING OF BOURDON TUBE PRESSURE GAUGE

 

-It was invented by Eugene Bourdon in the year 1849.

-It is used to measure high as well as low pressure.

-It is also known as Elastic type pressure transducer.

-The tube wall will have a thickness between 0.01 mm and 0.05 mm

-For low pressure measurement, tubes are generally made of Bronze.

-For High pressure measurement, tubes are generally made of nickel steel.

-Other material used for tube are :- phosphor-bronze, silicon bronze, Beryllium-copper, Inconel and other C-Cr-Ni-Mo alloys.
