Abstract

A top-pan scale with a scale pan which is supported on at least one force transducer (7) of a force measurement system (5) and with a corner load sensor which outputs a signal if the weighing goods are positioned eccentrically on the scale pan. The corner load sensor (10) has a flat underside via which it can be placed on, or attached to, the scale pan or a bottom pan of the scale. The corner load sensor also has a flat upper side on which a scale pan (4) can be placed or attached. The corner load sensor (10) is connected to a positionally fixed electronic processor (22) via a force-feedback-free connection (21). Embodiments of the corner load sensor can therefore be used for a wide variety of scale designs and can be retrofitted easily.
