KRAFTMESSEINRICHTUNG

摘要

An apparatus for the measuring of external forces by means of a preloaded roller bearing, provided with at least two strain gauges which serve to measure the forces applied to the bearings, in which apparatus the resistance variations of the strain gauge(s) are recorded individually, amplified individually and rectified individually, whereby signals which are proportional to the external forces are obtained through subtraction from the rectified signals, while due to said subtraction those parts of the individually amplified and rectified signals due to internal forces are eliminated.
