LW-2T-50K: heavy-duty wheel force transducer, 222 kN
The LW-2T-50K measures all the wheel forces and moments on class 8 trucks. Four-arm strain gage bridges give independent signals for the vertical, lateral and longitudinal forces, up to 222 kN radial (Fx, Fz) and 111 kN lateral (Fy) at the tire patch, and for the camber, steer and torque moments, 68 kN·m each. Non-linearity, hysteresis and crosstalk after correction are within 1 % of full scale. The stainless steel transducer is environmentally protected and temperature compensated, and operates from −40 to 125 °C. Its matching amplifier package adds X and Z accelerations, an encoder resolving 0.17° and remote shunt calibration.
The manual covers single and dual-wheel assemblies. Twenty-four ¾-10 bolts join the transducer to each adapter, tightened to 339 N·m; on dual wheels, the inner and outer rim adapters share the same bolts and stand-offs carry the amplifier bar. The matched amplifier and slip ring mount after the wheel nuts. A restraint rod to a magnetic bracket holds the slip ring stator, or the stator angle correction device on steered wheels. The CT3 interface box, powered at 9 to 36 V DC, runs the shunt calibration check and the zero.
It is used for on-road and off-road measurements, one transducer measuring the combined loads of a dual wheel set or a single tire, and also to monitor and control laboratory tests. On large farm equipment, it serves durability, vehicle dynamics and handling tests.
