Presentation

The LW12.8-50 Wheel Force Transducer is capable of measuring all of the wheel forces and moments on passenger cars and light duty trucks. It provides independent output signals for vertical, lateral, and longitudinal forces as well as camber, steer, and torque moments.

High grade stainless steel material and weatherproof sealing combine to provide excellent resistance to corrosion and environmental conditions making it ideal for on-road measurements; it can also be used to monitor and control laboratory tests. Temperature compensation of the wheel force transducer ensures stable output throughout a wide temperature range. In addition, all wires are precisely located to reduce sensitivity to magnetic effects.

Mounting and Data transmission:

The transducer LW12.8-50 outputs :

  • 3 forces
  • 3 moments
  • 2 accelerations X and Z
  • wheel speed and position

Both analog and CAN output are offered, other Fieldbus available in option. The raw signals are amplified in the amplifier mounted on the transducer, then sent to the conditionning module CT2 through the slip ring assembly.

CT2 Transducer Interface Box:

  • Performs real-time coordinate transformation and crosstalk compensation
  • Easy to use Zero, Shunt Calibration, and Bridge Power Off functions
  • Simultaneous Analog, CAN, & Ethernet signal outputs
  • Embedded web page enables user to change set-up options, move WFT measurement origin, view transducer static values, create .dbc file

Installation on Test Rig / non-spinning application

The wheel force transducer supports installation through flanges or hubs on test rig as well, spinning or not spinning.

Setup

The system configuration and setup is completely done within a simple webbrowser on a PC or laptop connected to the CT2 over LAN. no additional Software is needed. Web interface
