Abstract

Die Erfindung betrifft eine Vorrichtung zur Messung von Kräften, insbesondere Gewichten, oder kraftabhängigen Größen, wie Druck und Drehmoment, mit einem sich unter Krafteinwirkung verformenden Messkörper (1, 3) und einem mit dem Messkörper verbundenen, sich mit dem Messkörper unter Erzeugung eines Messsignals verformenden Sensorelement (4), sowie ein Verfahren zur Herstellung einer solchen Vorrichtung. Gemäß der Erfindung ist für das Sensorelement (4) ein mit dem übrigen Messkörper verschweißtes Trägerelement (3) vorgesehen. Das Sensorelement wird vor dem Verschweißen des Trägerelements (3) mit dem übri­gen Messkörper (1) auf das Trägerelement (3) aufgebracht.
