A pressure transducer, often called a pressure transmitter, is a transducer that converts the pressure into an analog electrical signal. Although there are several types of pressure transducers, one of the most common is the strain-gage base transducer.
The conversion of the pressure into an electrical signal is achieved by the physical deformation of the strain gauges which are attached to the diaphragm of the pressure transducer and wired in a wheat bridge configuration. The pressure applied to the pressure transducer produces a deflection of the diaphragm which introduces a deformation to the gauges. The deformation will produce a change of electrical resistance proportional to the pressure.
