Wheel instrumentation
Signals from the wheel, the brake, the tire and the hub, on the wheel the vehicle already has.
The package bolts onto the series wheel through a plate and collet lug nuts, and brings the signals of sensors in the wheel, the brake, the tire, the hub or the axle off the turning wheel. Waterproof, for the bench, the track, the open road or off-road, from forklift trucks to class 8 tractors.
- up to 30
- measurements collected at once
- 4 to 36
- slip ring circuits
- 5 000 ppr
- encoder resolution, wheel pulse transducer
- IP67
- with contacting rotary seals
The series wheel stays on the car.
The package goes on the wheel the vehicle already has. Nothing on the vehicle is modified.
The sensors are in the wheel, the brake, the tire or the hub. The package gives them a way off the turning wheel without replacing it.
Advantages
- The mounting plateIt bolts onto the original wheel through collet lug nuts machined for the vehicle. Plates exist for passenger cars, trucks and buses, and tractors.
- The rotating unitA slip ring with 4 to 36 circuits for sensor signals, with an optional encoder up to 1 024 ppr. Or an optical encoder alone, 50 to 5 000 ppr, rated IP67 with contacting rotary seals.
- Your signalsStrain gage, thermocouple, voltage or ICP signals cross the slip ring in analog form, with no pre-amplifier stage. Conditioners and on-board acquisition are options.
Wheel instrumentation selection
Wheel speed, rotation output, sealing. Models meeting every criterion.
Set the criteria. Closest models first.

Applications
-
Dynamics Side slip angle Side slip angle read without contact by an optical sensor, on a wheel or on the vehicle body. -
Speed Wheel speed and distance Wheel speed, vehicle speed and distance traveled, read from the rotation of the wheel itself. -
Powertrain Axle and half-shaft torque Drive torque measured on the production shaft, with a slip ring or telemetry to bring the signal out. -
Powertrain Truck solid axle torque Drive torque on a truck solid axle, read by strain gages inside the shaft and brought out at the wheel.

What engineers ask first
Does it fit an electric vehicle?
Yes. The wheel instrumentation system can be used on electric vehicles, including with the motor directly at the wheel.
Does the wheel have to be modified?
No. The system mounts on the original wheel through a plate and collet lug nuts machined for the vehicle.
Do the signals need conditioning on the wheel?
The transmission is analog, through a low-resistance slip ring designed for low-voltage signals such as thermocouples and strain gages. Conditioners and on-board acquisition systems are available as options.
Technical support
An application engineer answers within 24 hours on working days. When equipment fails during a campaign, diagnosis is remote and a loan unit can be shipped, depending on the project.
How support works- < 24 h
- first answer from an application engineer
- Over 30
- wheel force transducers in the loan and rental fleet
- 1 to 2 weeks
- typical calibration turnaround
Which package for your wheel?
Vehicle, wheel, signals to collect, speed. An application engineer answers with a reference and a price.
