ABSTRACT:
In a device for measuring forces by means of an anti-friction bearing which is provided with strain gauges at various measurement points, which serve to detect overroll extensions, two strain gauges connected as a half-bridge are used in each case, which are adapted to materials with different coefficients of expansion. By the use of such different strain gauges, temperatures and forces can be measured with one and the same measuring device, while force-dependent alternating-voltage fractions appearing at the center tapping of the half-bridge are filtered out of the total signal by a filter.
