Question

Which pressure measurement device has its construction where in, a hollow metal tube is bent like a hook and the end is closed, connected to dial indicator?

• A. Bourdon tube
• B. Manometer
• C. Barometer
• D. Pirani gauge

Answer 1

Answer:

A. Bourdon tube

Bourdon tube pressure gauge is a mechanical device used to measure medium to high pressures. It consists of a curved tube which winds or unwinds depending on the pressure difference between the inside and outside. The motion of the tube is against a spring torque, which indicates the pressure difference on a dial indicator.
