An elastic type of pressure-measuring instrument is of diaphragm type. The central deflection of the dia- phragm was found to be 0.25 mm of an applied pressure of 10 Pa. The output displacement of diaphragm has been fed to an LVDT (linear variable differential transducer) with a built-in amplifier having a sensitivity of 40 V/mm. Finally the output is displayed on an analog voltmeter which has a radius of scale line as 60 mm and has a voltage range from zero to 10 volts in an arc of 150. Determine the sensitivity of the given diaphragm gauge in terms of mm/bar (1 bar = 10 Pa).
