LW-2T-60K-S wheel force transducer 300 kN

LW-2T-60K-S: heavy-duty wheel force transducer, 300 kN

The LW-2T-60K-S is the lower-capacity of the two Michigan Scientific heavy-duty wheel force transducers for class 8 trucks and large off-road vehicles: 67,400 lbf (300 kN) radial (Fx, Fz), 33,700 lbf (150 kN) lateral at the tire patch (Fy) and 60,000 lbf·ft (81 kN·m) on the camber, steer and torque moments. One transducer measures the combined loads of a dual wheel set or a single tire, on 20 in and larger wheels and 285 mm or 335 mm hub bolt patterns. For higher loads, the LW-2T-100K-S takes 445 kN radial in the same outline.

Twenty-four Ø 17.5 mm through holes and M20 × 2.5 threads lie on a Ø 435.6 mm bolt circle. On dual wheels, both rim adapters bolt onto the transducer with the same M20 bolts, then the hub adapter with twenty-four more, tightened with a torque multiplier; stand-offs carry the amplifier bar. A magnetic restraint holds the slip ring stator vertical, 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.

The CT3 User Interface Box performs the real-time coordinate transformation and crosstalk correction, leaving less than 1 % of full scale, and outputs CAN FD, CAN 2.0 and Ethernet, with EtherCAT and analog outputs as options; an embedded webpage, reached over USB, configures the system. The transducer is weatherproof and is used on-road and off-road in all conditions, and to monitor and control laboratory tests.
