Advantages and Disadvantages of Bourdon tube pressure gauge

Advantages of Bourdon tube pressure gauge:

  • These Bourdon tube pressure gauges give accurate results.
  • Bourdon tube cost low.
  • Bourdon tube are simple in construction.
  • They can be modified to give electrical outputs.
  • They are safe even for high pressure measurement.
  • Accuracy is high especially at high pressures.

Limitations of bourdon tube pressure gauge:

  • They respond slowly to changs in pressure
  • They are subjected to hysterisis.
  • They are sensitive to shocks and vibrations.
  • Ampilification is a must as the displacement of the free end of the bourdon tube is low.
  • It cannot be used for precision measurement.
