ABSTRACT:
A capacitive type load cell utilizing a support, a diaphragm member mounted with respect to said support for movement relative thereto, said diaphragm having a conductive surface, and a capacitor plate attached to the diaphragm so that upon deflection of the diaphragm there will be relative movement between the diaphragm and the capacitor plate. The diaphragm is constructed to provide free edge bending characteristics both at its outer peripheral edges, and between the diaphragm and the load support button, to thereby reduce radial bending stresses in the diaphragm during loading.
