LW65 wheel force transducer 65 kN

LW65: wheel force transducer for cars and SUVs, 65 kN

The LW65 measures all the wheel forces and moments on passenger cars, SUVs and light-duty trucks, with X and Z accelerations up to ±100 g. It is rated 65 kN (14,500 lb) on Fx and Fz, 35 kN (7,850 lb) on Fy and 10.5 kN·m (7,700 lbf·ft) on all three moments, for a static weight of 1,320 kg. Non-linearity is 0.2 % of full scale or less on the forces and My, cross-axis sensitivity after correction 0.4 % or less. The IP67 transducer operates from −40 to 177 °C and adapts to 12 in and larger wheels; angular resolution is 0.17°.

Twenty-four M10 × 1.5 screws pass through the transducer into the rim adapter and twenty-four more fasten the hub adapter, torqued crosswise to 81 N·m; design guides give both adapters. With the slip ring, the amplifier carries a 20-circuit slip ring with a 512-pulse encoder, its stator held by a restraint rod or a stator angle corrector. With telemetry, a factory-mated telemetry and encoder ring feeds an inboard stator set with an alignment tool, read by the CT3 box.

Its IP67 design suits the harshest track and off-road measurements, and non-spinning applications that monitor and control laboratory test rigs. A Michigan Scientific video shows its telemetry set fitted to the front hub of a car.
