Abstract
An electronic balance with a balance scale (3) which is movably connected by a parallel guide consisting of an upper (4) and a lower guide rod (5) in a vertical direction to a system carrier (1) fixed to the housing, with at least two wire strain gauges (15) which are arranged in the vicinity of the ends of a guide rod (4), which ends are on the housing side, and which wire strain gauges measure the horizontal forces in the guide rod (4) which are caused by the torque transferred from the balance scale (3) onto the parallel guide, and with electronics which corrects the weight value emitted from the weighing receiver on the basis of the output signals of the wire strain gauges (15) and from stored comer-load correction factors that at least one of the guide rods (4) is supported on its housing-side end on an intermediate piece (18), that this intermediate piece (18) is connected by at least one approximately vertical thin web (13) and by a horizontal thin web (14) to the system carrier (1) fixed to the housing and that at least one wire strain gauge (15) is fastened to the horizontal thin web (14). This makes it possible to obtain a high output signal from the wire strain gauge in the case of a corner load without the stability of the parallel guide being adversely affected.
