Wheel 6-component Force Measuring System


This syatem enables measurement of 3 forces (Fx, Fy, Fz) acting on 3 orthogonal axes to the running axle at the wheel mounting part and 3 moments (Mx, My, Mz) around the axes.
The wheel itself is made to act as the sensor to detect the 6-component force and output signals are transmitted by the slip-ring to the 6-component signal processor.


●Thin and lightweight sensor
●The sensor ensures easy handling.
●Single 6-component signal processor supports four wheels.
A high-speed DSP improves the processing capability.
●Dedicated signal processor contains an indicator which is easy to view in the field with a user-friendly remote controller.


●6-component sensor
●Slip-ring unit
●6-component signal processor
●Data logger
●Data process/analysis software
