Bourdon Tube Pressure Gauge Construction And Working

Bourdon Tube Pressure Gauge Construction And Working. They can be modified to give electrical outputs. The working principle of the pressure gauge is through the elastic deformation of the sensitive element in the gauge.

This is due to the principle that a flattened tube tends to regain its circular form when pressurized. With the help of a simple pinion and sector arrangement, the elastic deformation of the bourdon’s tube rotates the pointer.

As the gauge pressure increases the tube will tend to uncoil, while a reduced gauge pressure will cause the tube to coil more tightly. The mechanical construction has to be highly accurate in the case of a bourdon tube gauge.

Construction Is Simple And The Cost Is Low.

Bourdon tube pressure gauges are the most frequently used mechanical pressure measuring instruments. Form vacuum to pressure as high as few thousand psi. Then the pressure change is transmitted to the pointer by the conversion mechanism of the movement in the watch.

The Applied Pressure Acts On The Inner Walls Of The Bourdon Tube.

The bourdon tube is also an elastic element type of pressure transducer. The free end connected to the pointer with the help of geared sector and pinion. A pointer connected to the end of the tube can be attached to a lever and a pointer calibrated to indicate pressure.

Bourdon Tube Pressure Gauges Can Be Used To Measure Over A Wide Range Of Pressure:

The nconstruct of a bourdon pressure gage is a simple scroll of brass ( typical) that is fixed at one end and allowed to straighten out along the length in doing so there is a small gaer attached to the needle which reads the deflection of the. Advantages of bourdon tube pressure gauge: Applications of bourdon tube pressure gauge:

They Can Be Modified To Give Electrical Outputs.

They cover measuring spans from. Bourdon tube pressure gauges are extensively used for local indication. Advantages of bourdon tube pressure gauge:

With The Help Of A Simple Pinion And Sector Arrangement, The Elastic Deformation Of The Bourdon’s Tube Rotates The Pointer.

When pressure is applied at the open, fixed. As the pressure in the tube increases, the coil unwinds. This instrument is by far the most common device used to indicate gauge pressure throughout the oil gas industry.
