Pressure Transducer Design

 

All force transducers can be adapted to measure pressure if an area can be defined and held constant. (Pressure = Force / Area) Pressure transducer design often uses a secondary transducer to measure elastic deformation or displacement of a mechanical element such as a diaphragm, bellows or optical fiber using a force or displacement transducer. Some pressure transducer designs are:

 

Gravitational Types - liquid columns, pistons, weights and loose diaphragms

 

Direct acting elastic types - elastic diaphragms, bellows and loaded tubes

 

Indirect-acting elastic - piston with elastic restraining member
