Abstract[German]
Die Erfindung betrifft einen Kraftmessbolzen (1) zur Messung von Kräften und/oder Momenten in kraft- und/oder momentenbeaufschlagten Bauteilen, umfassend eine Kraftmessfläche (2) auf welche ein dehnungsbasierter Sensor (3) aufgebracht ist, wobei der Sensor (3) über ein Sensorschichtsystem (4) verfügt, dass eine Schichtdicke von weniger als 200 µm aufweist, wobei das Sensorschichtsystem (4) eine elektrisch isolierende Isolationsschicht (5) besitzt, die unmittelbar an der Kraftmessfläche (2) anliegt, sowie eine verformungssensitive Messschicht (6), welche auf der Isolationsschicht (5) aufgetragen ist.[English]
The invention relates to a force-measuring bolt (1) for measuring forces and/or torques in components to which forces and/or torques are applied, said force-measuring bolt comprising a force-measuring surface (2) to which a strain-based sensor (3) is applied, wherein the sensor (3) comprises a sensor layer system (4) which has a layer thickness of less than 200 µm, wherein the sensor layer system (4) has an electrically insulating insulation layer (5) which lies directly on the force-measuring surface (2), and a deformation-sensitive measuring layer (6) which is applied to the insulation layer (5).[French]
L'invention concerne un boulon de mesure de force (1) pour mesurer des forces et/ou des couples dans des composants auxquels sont appliqués des forces et/ou des couples, ledit boulon de mesure de force comprenant une surface de mesure de force (2) sur laquelle est appliqué un capteur de déformation (3), le capteur (3) comprenant un système de couches(4) ayant une épaisseur inférieure à 200 µm, le système de couches (4) comportant une couche d'isolation électriquement isolante (5) qui repose directement sur la surface de mesure de force (2), et une couche de mesure sensible à la déformation (6) qui est appliquée à la couche d'isolation (5).
