Fastener arrangement for deformation sensor

摘要

A fastener arrangement for clamping a sensor element to a member whose deformation is to be monitored so as to elimiate signal distortions due to the clamping process and to settling phenomena. The sensor element is formed at its contact point with the member to be monitored by pressing between a die and counter-die as the clamping screws are tightened to provide a form-fit closure of the sensor element with the member to be monitored. The die and counter-die are formed on the adjacent surfaces of the member to be monitored and a torsion member; between which surfaces, the sensor element lies. The screw support member can be arranged to isolate the screw turning moments from the sensor element jointly with the form-fit closure feature.
