Biofidel measuring devices are used to validate safety in collaborative workplaces. In these workplaces, humans work together with robots that are equipped with a Power and Force Limiting function (PFL). In this experimental comparison, differences between devices and possible causes are examined more closely. Safety-related parameters are identified in a literature review. Focusing on mechanical aspects, three biofidel measuring devices are analysed and compared in an experimental test series. To this end, a linear motor and a pendulum are used and the steps for comparing concepts are proposed and applied. Depending on the stiffness settings and the materials used, geometry effects on the force-deformation behaviour are shown. An oscillation occurred in one case. The comparison of the three devices shows average differences of 5% in measured peak force between them. This study helps to achieve uniform and comparable results in practice.
