ABSTRACT:
A low pressure capacitance measurement device where capacitance base members are constructed from metal and one of the base members arranged to be torqued relative to the other base member where the stress level is maintained within the elastic limits of the metal and the torque force is developed by a bellows which acts on a moment arm to torque the base member about its torque displacement axis.
