Abstract:
1. A weight sensor for an electronic balance, the weight sensor including: (a) a base body; (b) a load receiver spaced apart from the base body along a first axis; (c) guide members connected between the base body and the load receiver so that the load receiver is movable along a second axis with respect to the base body, the second axis being perpendicular to the first axis; (d) an elongated first force-translating element coupled to the load receiver to receive a deflecting force in response to a load acting on the load receiver along the second axis, the first force-translating element being located asymmetrically relative to a sensor plane which is defined by the first and second axes and which symmetrically divides the load receiver; and (e) a coil through which an electrical current is applied to compensate a deflection of the first force-translating element induced by the load acting on the load receiver, (f) wherein the first force-translating element, base body, load receiver, and guide members are monolithically formed.
