How Pressure Transducer Works?

In Pressure Transducer, the electrical interpretation of pressure is based upon the principle of operation of a strain gauge, wherein structural deformation of the load sensitive member of the device called wire grid is measured.

When the strain gauge is subjected to load the wire grid is stretched, changing its diameter and length and its electrical resistance, thus through measurement of the change in resistance of the wire grid with the gage under stress and evaluation of the force producing the load is obtained. This operation involve load and pressure from 100 pound to more than 10,000 psi.
