The LW-2T-30K Wheel Force Transducers (WFT) are capable of measuring all of the wheel forces and wheel moments on commercial vehicles, skid steers, medium duty trucks, off-road equipment, and large forklift trucks. The model provides independent output signals for vertical, lateral, and longitudinal forces as well as camber, steer and torque moments. It is completely weatherproof making it ideal for on-road and off-road measurements. 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.
