Pressure Transducers and Transmitters
A pressure transducer, often called a pressure transmitter, is a sensor that converts pressure into an analog electrical signal. Although there are various types of transducers, one of the most common is the strain-gage wheatstone bridge pressure transducer.
The conversion of pressure into an electrical signal is achieved by the physical deformation of strain gages which are bonded into the diaphragm of the pressure transducer and wired into a wheatstone bridge configuration. Pressure applied to the transducer produces a deflection of the diaphragm which introduces strain to the gages. The strain will produce an electrical resistance change proportional to the pressure...
