Abstract: A 6-component load cell used for measuring triaxial force and moment components is disclosed. The load cell has a sensing unit and an external case. In the sensing unit, upper and lower rings individually have a plurality of connectors and arcuate thick parts. The sensing unit also has a cross beam, consisting of horizontal and vertical parts crossing at right angles with a plurality of vertical and transverse binocular openings being formed on the two parts. A radial slit is formed at each corner of the junction of the cross beam. A plurality of strain gauges are attached to the cross beam. The external case has upper and lower parts, individually having a plurality of arcuate openings corresponding to the arcuate thick parts of the sensing unit. The lower part of the case also has a plurality of cord lead openings at the side wall.
