6 Bileşenli Tekerlek Kuvvet Ölçüm Sistemi/ Wheel 6-component Force Measuring System

High reliability and accurate transmission of slip-ring signals

●Thin and lightweight sensor 

●Slip-rings ensure 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 userfriendly remote controller.


This system enables measurement of 3-component force (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.
