Digital Telemetry Type
6-Component Wheel Force Measuring System
The 6-Component Wheel Force Measuring System is
comprised of the 6-Component Wheel Force Transducer
and the exclusive 6-component force analyzer. There are
two types available, the slip-ring type and digital telemetry
type, each using a different method to transfer the
6-component force information. The digital-telemetry 6-
Component Wheel Force Measuring System is comprised
of the 6-Component Wheel Force Transducer SLW-
20KND into which a miniature transmitter is built, the 6-
Component Force Analyzer MFT-306T, and the Telemetry
Receiver DT-24R. There are two 6-Component Wheel
Force Transducer SLW-20KND models, one with a rotary
encoder type angle detector and one with a non-contact
type angle detector. The Receiver DT-24R is lightweight
and so can be attached with suction holders. The 6-
Component Force Analyzer has the voltage output
built-in to output 6-component wheel force, tire rotation
count, angle, and other data. The 6-Component Force
Analyzer, which is controlled through a PC, comes
standard with the control software MFT-7306T.

Digital telemetry type 6-Component Wheel Force Transducer SLW-ND
Digital Telemetry Type High-Accuracy 6-Component Wheel Force Transducer SLW-NE
This digital-telemetry 6-Component Wheel Force Transducer
is comprised of a load cell, which detects external
forces passed to the tires from a road surface while driving
as the orthogonal three-component force and the three
moments around it, and the tire rotation angle detector.
After digital conversion in the load cell, the detected threecomponent
force, three moments, and tire rotation angles
are wirelessly sent to onboard 6-Component Force
Analyzer MFT-306T through the Telemetry Receiver
DT-24R. The receiver, which can be installed in the passenger
car, needs no cable routed from the outside of the car.
There are two Transducer models in the line up differing in
their tire rotation angle detector, one has a rotary encoder
type and the other, a non-contact type. The former can be
installed with the Wheel Alignment Displacement Transducer
(WAD-1B) that is used to measure wheel alignment at
the same time as the six-component forces. To support
wheel sizes and around-hub dimensions that differ with
each car type, using the "exclusive rim" and "hub adapter" can make installation possible into every passenger car
type with a wheel size of 15 inches or larger.
The SLW-NE is added to the ordinary SLW-ND and the stability of output waveform in running is more improved.
Features
- No supporters and cables outside the passenger car - Safe car driving
- Signals from the 6-Component Wheel Force Transducer received wirelessly in the car, requiring no cables routed inside and outside the car
- Installable into every passenger car type using the exclusive rim and hub adapter
- AA batteries used. Use of secondary batteries also possible
MFT-306T Digital-telemetry type 6-Component Force Analyzer
The Digital-telemetry 6-Component Wheel Force Transducers
SLW-ND attached to the axle shafts allow the
external forces passed to the tires from the road surface to
be input as an orthogonal three-component force and the
three moments around them. After being amplified and
converted digitally in the force transducer, an input signal
is wirelessly sent to MFT-306T through the Receiver
DT-24R. Received data is used to digitally operate the
crosstalk correction between each component force and
the rotation correction (X and Y components only). 6-component force data, tire rotation count signal are output
in voltage form through the output connector of front
panel. Monitoring is done through a PC, controlling 6-Component Force Analyzers up to 4 units. The control
software MFT-7306T comes standard with the device.
After being set up, the analyzer can perform measurement
by itself with the PC disconnected.
Features
- Small and lightweight - Reduction of installation area
- High-speed operation of crosstalk, rotation correction, etc.
- 6-component force data, tire rotation count signal output in voltage form
- Measurement data transferred wirelessly by built-in telemetry
- Up to 4 controllable units
