Model LW150 Wheel Force Transducer

• 33,700 lb (150 kN) radial load capacity
• 16,850 lb (75 kN) lateral load capacity
• Measures 3 forces and 3 moments
• Measures X & Z accelerations
• Adapts to 19.5 in and larger wheels
• Remains within vehicle width
• Swappable slip ring or telemetry system for signal transmission

The LW150 Wheel Force Transducer (WFT) is ideal for measuring all of the wheel forces and moments on the front axle of class-8 trucks. It provides independent output signals for vertical, lateral, and longitudinal forces as well as camber, steer, and torque moments. The LW150 uses a thin design and telemetry to remain within the vehicle width, making the LW150 ideal for on-road testing. The robust IP67 design also allows for the harshest track and off-road measurements. The LW150 offers the convenience of utilizing an outboard slip ring signal transmission or in-board telemetry signal transmission.

When using an outboard slip ring, the amplifier package easily mounts onto the transducer. With an outboard slip ring the LW150 can be used with 19.5 in and larger wheel. Telemetry can be used with 22.5 in or larger wheels. Using the outboard slip ring amplifies and digitizes the transducer signals before they pass through the slip ring. Michigan Scientific Slip Ring Assemblies are known worldwide for their signal quality and robust design.

The CT3 User Interface Box performs real-time coordinate transformation and crosstalk compensation and provides CAN-FD, CAN2.0, and Ethernet signal outputs. EtherCAT and Analog signal outputs are also available with optional modules. An embedded webpage accessed via USB allows the user to easily configure the WFT system. A front display indicates important information and prompts for the user.
