Bourdon tube pressure gauge
Bourdon tubes are tubes with an oval cross-section which have been bent into a circle. If pressure is applied to the inside of the Bourdon tube, its cross-section is changed, and it approaches a circular shape. The resulting mechanical stress causes the tube to bend. The unfixed end of the tube is set into motion, the extent of which is a measure of pressure. The extent of this motion is indicated at the gauge by means of a mechanism. The circular tubes which are bent to an angle of approximately 250° are used for pressure ranges of up to roughly 60 bar.

Bourdon tubes are only protected against overloading to a limited extent. In order to be able to execute especially difficult measuring tasks, a diaphragm seal can be installed upstream from the pressure gauge which functions as an isolating and protective device. Indicating ranges lie within a spectrum of 0 to 0.6 and 0 to 4000 bar with indicating accuracies (accuracy classes) of 0.1 and 4.0 %.
