A dual capacitor device for utilizing dependent capacitances for measurement purposes where a first capacitor base member and a second capacitance base member are arranged with parallel capacitor surfaces in parallel planes and where the parallel capacitor surfaces are located on opposite sides relative to a central transverse plane to define first and second capacitors. The second capacitor base member has a centrally located section connected to an outer section of the second capacitor base member by a torsion beam and the centrally located section is attached to the first capacitor base member by a coupling member. Angular displacement of the outer section relative to the centrally located section about the displacement axis produces a capacitance change in the first and second capacitors. A torque force applied to the outer section by a spirally wound bourdon tube in response to pressure develops a low force on the torsion beam which is less than the micro yield point of the torsion beam material and develops a micro dimensional angular displacement of the outer section of the second capacitance base member and a capacitance change as a function of the force.
