LW-2T-40K Wheel Force Transducers (WFT) provides 3 forces and 3 moments at the wheel on trucks, off-road equipment, and large forklift trucks. Force Capacity: 178 kN / Moment Capacity: 40 kNm . 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.
