F3A3A11B – Load Cell – Acetabulum left

Load Cell, 3-axial
Location: Acetabulum left

Technical description

The applied force causes compression or strain of the base body. The deformation is measured using strain gauges. The wiring of multiple strain gauges for a full bridge circuit compensates for the temperature influence on the zero signal and the cross-influence from other force and torque application.
