- Nevertheless, because of its simplicity and low cost, and the large selection of pressure ranges which are available, the Bourdon gauge is widely used in engineering practice.
- A Bourdon tube is coupled to an indicating needle driving mechanism of a Bourdon gauge at one end by way of a connecting arm fixed in place by welding.
