Introduction

The LW12.8-50-TEL 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 Telemetry and Induction Power electronics are packaged to create a low profile assembly. The coordinate transformation box (CT2-TEL) provides CAN bus, Ethernet, and high level Analog signal outputs. CT2-TEL is field upgradeable via an embedded web page and can be set up through a web browser.

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

Telemetry Stator

Receives and Decodes the telemetry signal from the Transducer
Provides High Resolution Speed & Position Signals
Mounts inboard of the Transducer

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
