N3AIA11A – Load Cell – Lumbar Spine

Load Cell, 3-axial
Location: Lumbar Spine

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.
