Bellows, Diaphragms and Bourdon Tubes Mechanical pressure-sensing elements include the bellows, the diaphragm, and the bourdon tube. Each of these devices converts a fluid pressure into a force. If unrestrained,...

Types of Bourdon Tube

S Bharadwaj Reddy
Basically they are designed to follow the physical law that, within the elastic limit, stress is proportional to strain (Hooke’s Law), that is deflection is proportional to the pressure applied....

Absolute Pressure Gauges Principle

S Bharadwaj Reddy
These instruments are used where pressures are to be measured independent of the natural fluctuations in atmospheric pressure. As a general rule all the known types of element and measuring...
