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
