The LW65 Wheel Force Transducer (WFT) is capable of measuring all of the wheel forces and moments on passenger cars, SUVs, and light duty trucks. It provides independent output signals for vertical, lateral, and longitudinal forces as well as camber, steer, and torque moments. The LW65’s robust, IP67 design is ideal for the harshest track and off-road measurements as well as non-spinning applications to monitor and control laboratory test rigs. For spinning applications, the LW65 offers the convenience of utilizing an outboard slip ring signal transmission or in-board telemetry signal transmission.

For use on track, road or test rig

The LW65 Wheel Force Transducer is perfectly wheatherproof and robust, and can be used on road, off-road, snow, mud, stones and trees. The same transducer can be used on test rig as well, ensuring perfect consistency between data measured and tracked and road profiles simulated on dyno.


The transducer mounts easily on vehicle or test rig (spinning or not spinning) using adapter parts designed for this purpose.

The signal transmission between the transducer and the data acquisition system can be made wired (slip ring option) or wireless (telemetry). When using an outboard slip ring, the amplifier package easily mounts onto the transducer. It amplifies and digitizes the transducer signals before they pass through the slip ring. The amplifier package also includes X and Z acceleration outputs and performs remote shunt calibration of the transducer. Michigan Scientific Slip Ring Assemblies are known worldwide for their signal quality and robust design.

The measurement signals are processed in real time according the application requirements. CT2 Transducer Interface Box performs real-time coordinate transformation and crosstalk compensation, and provides analog, CAN. EtherCAT signal outputs are also available in option. An embedded webpage allows the user to easily configure the WFT system.

CT2 Transducer Interface Box:

  • Performs real-time coordinate transformation and crosstalk compensation
  • Easy to use Zero, Shunt Calibration, and Bridge Power Off functions
  • Simultaneous Analog, CAN, & Ethernet signal outputs
  • Embedded web page enables user to change set-up options, move WFT measurement origin, view transducer static values, create .dbc file
