Force measuring machine for tensile and compressive forces
The diversion device is equipped with three crossheads which can be displaced, so that the force measuring machine can measure loads induced by tensile forces and by compressive forces within one and the same set-up. Another design also allows force diversion to be realized via a bearing. First, the compressive force is generated in the force generation clear-ance by means of the deadweights. Then, a tensile force is generated by diversion via an appropriate inversion principle.
Economic Significance
Based on the new diversion device, innovative force measuring machines can be designed, also for applications with zero crossing; they will provide calibration laboratories in research and industry as well as other NMIs with new, application-oriented calibration capabilities.
Development Status
PTB is currently developing this invention into a prototype. A patent application has been filed. Licenses for the utilization of this new method are available.
