Heavy-equipment wheel force transducer, 445 kN

The LW-2T-100K measures all the wheel forces and moments on class 8 trucks, large off-road vehicles and heavy equipment. Four-arm strain gage bridges give independent signals for the vertical, lateral and longitudinal forces, up to 445 kN radial (Fx, Fz) and 225 kN lateral (Fy) at the tire patch, and for the camber, steer and torque moments, 135 kN·m each. Non-linearity and crosstalk after correction stay within 1 % of full scale, hysteresis below 0.5 %. The environmentally protected, temperature-compensated stainless steel transducer adapts to 22.5 in and larger wheels and operates from −40 to 125 °C.

One transducer takes the combined loads of a dual wheel set or a single tire. The matching amplifier package mounts onto it, amplifies and digitizes the bridge signals before the slip ring, adds X and Z accelerations and an encoder resolving 0.17°, and performs remote shunt calibration. The CT2 interface box makes the coordinate transformation and crosstalk compensation in real time, with zero, shunt calibration and bridge power off functions and analog, CAN and Ethernet outputs; its embedded web page sets up the system and moves the measurement origin.

It is used for on-road and off-road measurements and to monitor and control laboratory tests. On large farm equipment, it serves durability, vehicle dynamics and handling tests.
