Abstract
A force and moment measuring device has multicomponent force measuring cells arranged in opposite pairs at either side of a force introducing platform or mounting plate, viewed in the direction of their tension/pressure sensitivity. The opposed force measuring cells are preloaded by a common preloading screw extending in the direction of their tension/pressure sensitivity and passing through the force introduction platform without friction. The opposed force measuring cells have opposed tension/pressure sensitivity orientation. The tension/pressure measuring signals resulting from a temperature change occurring in the mounting plate and/or in the common preloading screw are cancelled out by opposed measuring cells, while the measured values generated by a force acting in one direction are added together.
