The Lightweight LW12.8-20 Wheel Force Transducer (WFT) System is capable of measuring all of the wheel forces and moments on medium and small cars. When the LW12.8-20 is fully assembled with a titanium hub adapter, 6 x 16 inch solid machined aluminum rim adapter, amplifier, slip ring, and titanium bolts, the system weight is 24.7 lb (11.2 kg) which is close to most standard aluminum rims. It is important in durability testing and simulation to match the unsprung mass of the test vehicle to the unsprung mass of the production vehicle, so that relative damage from durability testing is an accurate representation of the production vehicle.

The Telemetry version Wheel Force Transducer, LW12.8-20-TEL, when fully assembled with a titanium hub adapter, 6 x 16 inch solid machined rim adapter, and titanium bolts, weighs 25.9 lb (11.7 kg) which is also close to some standard aluminum rims.

Both slip ring and telemetry versions are completely weatherproof, making them ideal for on-road and off-road measurements in all conditions. They can also be used to monitor and control laboratory simulator tests.
The CT2 Transducer Interface Box performs real-time coordinate transformation and crosstalk compensation, and outputs analog, CAN, and Ethernet signals. An embedded webpage allows the user to configure the WFT system.
