Abstract

This report describes the analysis and evaluation of a multi-bridge force transducer with a newly developed multi-channel amplifier system, which is able to measure the different individual strain gauge full bridges with up to eight high-precision amplifiers in an absolutely simultaneous way and with small measurement uncertainty. With the suitable evaluation software, it is then possible to calculate the sums and differences of the different output signals and with those, perform an analysis of the force transducer’s measurement behavior. It is also possible to gain results of the behavior of the materials testing machines in the presence of side forces, moments as well of swinging of the masses of dead weight force standard machines.
