Abstract

An arrangement for measuring extension, compression, force and twist on variable length components using strain gauges has a housing with two blades (9, 11) at a distance apart. One blade is fixed wrt. the housing and the other can move or bend in the direction of component length variation. - A raising and lowering mechanism activates clamp magnets (34) when the arrangement is lowered to fix the housing to the measurement component, whereby the blade tips dig into the component's surface. When the arrangement is raised the magnets are deactivated and the tips are disengaged.
