Strain gauge pressure transmitter uses advanced metal foil strain gauges as sensing element. Those strain gauges consist a Wheatstone bridge and can feel the changes of the strain gauge’s resistance and convert these changes to “mV”electrical signal, the signal will be amplified to standard current or voltage output after it is conducted by the special amplifiers.
