Advantages:
- These pressure gauges give accurate results
- They costs low
- They are simple in construction
- They can be modified to give an better electrical outputs
- They are safe even for high pressure measurement
- Accuracy is high especially at high pressure
Disadvantages:
- They respond slowly to changes in pressure
- They are subjected to hysteresis
- They are sensitive to shocks and vibrations
- Amplification is a must as the displacement of the free end of the bourdon tube is low
- It cannot be used for precision measurement

What type of pressure gauge can measure vacuum pressure?
A Bourdon Tube or a Bellows gauge
A Bourdon tube is often found in a?
A bourdon tube is a type of curved tube where the inside radius is smaller than the outside radius. As Force = Pressure x Area this means that when a pressure is applied internally to the tube the greater surface area on the outside causes the tube to straighten out. This is connected via a mechanical linkage to dial on the front of the gauge. Your typical industrial pressure gauge is the Bourdon Tube tyep.
What is bourdon tube pressure gauge?
An elastic transducer, that is bourdon tube which is fixed and open at one end to receive the pressure which is to be measured. The other end of the bourdon tube is free and closed. The cross-section of the bourdon tube is eliptical. The bourdon tube is in a bent form to look like a circular arc. To the free end of the bourdon tube is attached an adjustable link, which is inturn connected to a sector and pinion as shown in diagram. To the shaft of the pinion is connected a pointer which sweeps over a pressure calibrated scale.
How does bourdon tube gauge work?
A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside, there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is less than the ambient air pressure), or the force will tend to straighten out the pipe (if the pressure is higher inside). This force can be measured, and from the measurement of this force, the gauge pressure within the pipe can be calculated.
Why does the Bourdon gauge not read zero pascals when no pump is connected and the valve is open?
It is because air can still go into the metal tube, and the atmospheric pressure (14.7 psia) will still force the tube to uncoil a bit. But the reading won't be very high.
Which amongst Bourdon's pressure gauge and manometer is preferred?
Bourdon gauge
Can bourdon's tube pressure gauge be used to measure negative pressure?
Bourdon's tube pressure gauge cannot be used to measure negative pressure. This is because absolute pressure must be measured and the Bourdon gauge only indicates the gauge pressure.
What does bourdon gauge measure?
Pressure.
What did Eugene Bourdon invent?
Eugene Bourdon invented and patented the Bourdon tube pressure gauge.
What type of pressure gauge can measure vacuum pressure?
A Bourdon Tube or a Bellows gauge
What is the function of the adjusting screw in the Bourdon gauge?
Bourdon gauge is a type of aneroid pressure gauge consisting of a flattened curved tube attached to a pointer that moves around a dial. As the pressure in the tube increases, the tube tends to straighten and the pointer indicates the applied pressure.
Can we use bourdon's pressure gauge to measure air pressure?
cannot

What is the pressure measuring device invented by a frenchman in the 18th century?
In 1849, the Bourdon tube pressure gauge was patented in France by Eugene Bourdon.
