The central deflection of the diaphragm of an elastic type pressure measuring instrument was
found to be 0.25mm of an applied pressure of 106𝑝𝑎. The output displacement of diaphragm
has been fed to a Linear variable differential transducer (LVDT) with a built in amplifier
having a sensitivity of 40V/mm. Finally the output is displayed on an analog voltmeter which
has a radius of scale line as 60mm and has a voltage range from zero to 10 volts in an arc of
. Using a well labelled diagram, determine the sensitivity of the given diaphragm gauge
in terms of mm/bar (1 bar=105𝑝𝑎).
