Presentation

The LW-2T-20K Wheel Force Transducer (WFT) is capable of measuring all of the wheel forces and moments on light and heavy duty pickup trucks vans and SUVs. It provides independent output signals for vertical, lateral, and longitudinal forces as well as camber, steer, and torque moments. Being completely weatherproof, it is ideal for on-road and off-road measurements in all conditions. It can also be used to monitor and control laboratory tests. One WFT measures the combined loads for either a dual wheel set or a single tire. The matching Amplifier / Slip Ring package easily mounts onto the transducer. It amplifies and digitizes the transducer signals before they pass through the slip ring.
