The LW-2T-100K-S Wheel Force Transducers (WFT) is used to measure forces (up to 445 kN) and moments (up to 108 kNm) up to on class 8 trucks and large off-road vehicles. It provides independent output signals for vertical, lateral, and longitudinal forces as well as camber, steer and torque moments. Being completely weatherproof, it's are ideal for on-road and off-road measurements in all conditions. 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.
