Forklift wheel force transducer, 93 kN

The LW9.5-HS measures all the wheel forces and moments on forklift trucks and other heavy vehicles with small wheels: vertical, lateral and longitudinal forces, and camber, steer and torque moments. Its 4-arm strain gage bridges are rated 93 kN (21,000 lb) on Fx and Fz, 45 kN (10,000 lb) on Fy and 9.5 kN·m (7,000 lbf·ft) on all three moments. Non-linearity is below 1 % of full scale, hysteresis and cross-axis sensitivity after correction below 0.5 %. The rugged stainless steel transducer is weatherproof and temperature compensated, operates from −40 to 125 °C and adapts to 10 in and larger wheels.

The matching amplifier package mounts onto the transducer. It amplifies and digitizes the strain gage, encoder and accelerometer signals before the slip ring, adds X and Z accelerations up to 55 g and performs remote shunt calibration; its internal smart chip holds the calibration, zero and shunt values. A high-resolution encoder gives position and speed, at 0.17°. The CT2 box performs coordinate transformation and crosstalk compensation in real time, with zero, shunt calibration and bridge power off functions, set up from an embedded web page.

Being completely weatherproof, it is designed for testing forklift trucks in all conditions, and it can also be used to monitor and control laboratory tests.
