Presentation

The LW-2T-60K-S Wheel Force Transducers (WFT) is used to measure forces and moments on class 8 trucks and large off-road vehicles. It provides independent output signals for vertical, lateral, and longitudinal forces as well as camber, steer and torque moments. Being completely weatherproof, it's are ideal for on-road and off-road measurements in all conditions.

Signal processing and data transmission

The transducer ** LW-2T-60K-S** outputs :

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

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

Amplifier and Slip Ring Package: CT2 Transducer Interface Box:
Internal X & Z accelerometers Performs real-time coordinate transformation and crosstalk compensation
High resolution encoder for position & speed measurement Easy to use Zero, Shunt Calibration, and Bridge Power Off functions
Internal smart chip contains all calibration, zero, & shunt values Simultaneous Analog, CAN, & Ethernet signal outputs
Provides signal conditioning & amplification to the transducer strain gage signals Embedded web page enables user to change set-up options, move WFT measurement origin, view transducer static values, create .dbc file
Digitizes Transducer, Encoder, & Accelerometer signals
Supports slip ring
Transducer + amplifier and slip ring Conditionning module CT2
Capteur + AMP et Slip Ring CT2

Installation and Data transmission

Vehicle / Spinning application

The matching Amplifier / Slip Ring package easily mounts onto the transducer. It amplifies and digitizes the transducer signals before they pass through the slip ring. The installation on the wheel is completed through a dedicated wheel rim (single or twin) and hub.

Single rim wheel Twin rim wheel double
Simple Double

Test Rig / non-spinning application

The wheel force transducer supports installation through flanges or hubs. An amplifier mounts directly on the transducer, and the cross-talk compensation is completed into an embedded electronics. Output signals are analog or CAN. Other interfaces available on demand.

the system configuration and setp 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
