Abstract
A fluid pressure differential measuring instrument comprises a diaphragm that is displaced by a pressure differential between two environmental pressure zones. Diaphragm displacement induced by the pressure differential between the two zones is converted to a torsional strain upon a cylindrical element in a third environmental zone. The torsional strain is measured by calibrated electrical sensing means positioned physically in the third environmental zone.
