Multicomponent force/torque sensor with integrated calibration system

摘要

A multicomponent force and torque sensor with integrated calibration capabilities is shown. The system uses the Kibblebalance principle to provide traceable force and torque measurements. This is possible by integrating standards for position, angle, voltage, resistance and time measurement. In this way, calibration operations based on deadweights and the use of local gravity acceleration are avoided. A prototype of the system for measuring forces and torques in a range of +-2 N and +-0.1 N m respectively was implemented. A maximal relative expanded measurement uncertainty (k=2) of 1.10(exp -4) is expected for the force and torque measurements. Experimental results used to calibrate the integrated position/ angle and voltage measuring systems are shown.
