Wheel force transducer for cars, 50 kN, up to 177 °C
The LW50 measures all the wheel forces and moments on passenger cars and light-duty trucks. It is rated 50 kN (11,200 lbf) on Fx and Fz, 25 kN (5,620 lbf) on Fy and 6.5 kN·m on all three moments, for a static weight of 1,020 kg. Non-linearity and hysteresis are 0.25 % of full scale or less, cross-axis sensitivity after correction 0.4 % or less. The IP67 transducer, Ø 342.90 × 21.59 mm, weighs 4.4 kg, operates from −40 to 177 °C and adapts to 12 in and larger wheels.
Its inner circle has sixteen M10 × 1.5 threaded holes, its outer circle sixteen through holes. With the outboard slip ring, the amplifier package mounts onto the transducer, adds X, Y and Z accelerations up to ±100 g and digitizes the signals; a high-resolution optical encoder gives position and speed, at 0.17°. The inboard telemetry package uses a magnetic encoder and an induction-powered stator. The CT3 box resolves the loads in real time, with zero, shunt calibration and zero angle functions, a front display and a web page over USB.
It is designed for the harshest track and off-road measurements on passenger cars and light-duty trucks, and for non-spinning applications that monitor and control laboratory test rigs.
