# Bellows Pressure Gauge Working Principle

Bellows Pressure Gauge Working Principle. Advantages of bellows pressure gauge. It is not suitable for high pressure measurement.

Differential Pressure Gauge Principle Instrumentation Tools from instrumentationtools.com

The basic way of manufacturing bellows is by fastening together many individual diaphragms. It is not suitable for high pressure measurement. As pressure is applied. it acts on the bellows on the free end. causing it to expand and produce movement.

It can be used for measuring low and moderate pressure. Bellows element is the elastic element which gets deflected at the free end when pressure is applied through fixed end.

The working principle of the pressure gauge is through the elastic deformation of the sensitive element in the gauge. System or line pressure is applied to the internal volume of the bellows.

Then the pressure change is transmitted to the pointer by the conversion mechanism of the movement in the watch. The bellows element. basically. is a one piece expansible. collapsible and axially flexible member.

#### Each Have Specialized Application In Different Industrial Processes.

Bellows pressure gauge it is a device. the pressure responsive element is made of a thin metal tube with a deep circumference when the pressure changes as the elastic elements increase or decrease. Bourdon tubes are easy to use and direct pressure measurement device. Then the pressure change is transmitted to the pointer by the conversion mechanism of the movement in the watch.

#### Bellows Pressure Element Is Works On The Principle Of Elasticity.

Pressure switch bellows working principle. This free end deflection can be taken as the measure of pressure inside it. It is not suitable for high pressure measurement.

#### Like A Diaphragm. Bellows Are Also Used For Pressure Measurement. And Can Be Made Of Cascaded Capsules.

Suitable for absolute pressure as well as gauge pressure. Disadvantages of bellows pressure gauge. A pointer is connected to it which indicates reading on the circular dial.

#### And May Have As Many As 24 Folds.

The diameter of the bellows ranges from 0.5 to 12 in. This arrangement indicates the gauge pressure. As pressure is applied. it acts on the bellows on the free end. causing it to expand and produce movement.

#### Bellow Pressure Gauge. Working Principle

The bellows element. basically. is a one piece expansible. collapsible and axially flexible member. In the second arrangement. the differential pressure is also indicated. Like a diaphragm. bellows are also used for pressure measurement. and can be made of cascaded capsules.
