New Generation of UCI Probes with Accurate Force Detection and Their Applications and Practical Benefits

C. Frehner, J. Meier

Abstract

In this paper a new generation of UCI probes will be introduced. In contrast to regular UCI probes which use a spring in combination with an end switch to trigger the measurement, these probes are equipped with an internal force sensor to make them adjustable to different test loads. As this technology allows to monitor the applied test load constantly, it brings additional benefits to the user. <BR />These possibilities will be described and explained in this paper. The advantages shall be presented and practical examples shall be given where they can be used. Furthermore, they will be supported with measurements on real test samples to quantify the real upside over traditional probes. <BR />To conclude this paper an outlook will be given with additional options to improve the UCI measurement principle further and to show in which direction future developments will go.
