Presentation

The LW-2T-100K is the Wheel Force Transducer (WFT) with highest capacities in the portfolio. It provides moment and force measurements on class 8 trucks, large off-road vehicles and heavy equipment. It provides independent output signals for vertical, lateral, and longitudinal forces as well as camber, steer and torque moments. The transducer is completely weatherproof making it ideal for on-road and off-road measurements. It can also be used to monitor and control laboratory tests. One sensor measures the combined loads for a dual wheel set or a single tire.
