Table 26: Wheel Sensor Maximum Pulse Rates
An example of a compatible DMI is the Kistler Wheel Pulse Transducer CWPTA411 (WPT). See
l
A transducer traditionally fits to the outside of a non-drive wheel. A pulse is then generated from the trans-
ducer which is fed to the receiver.
l
The WPT mounts to the wheel lug nuts via adjustable mounting collets. The torsion protection rod, which
maintains rotation around the wheel axis, affixes to the vehicle body with suction cups. Refer to the Kistler
WPT (part number CWPTA411) user manual for mounting instructions.
Figure 29: Kistler WPT
Kistler provides an M12 to DB9 cable for use with the WPT DMI. However, certain revisions of this
cable do not bring through all four signal inputs. SPAN systems require at a minimum the A+ and A- sig-
nals for distance. All four signal inputs are required to measure both distance and direction correctly.
See your WPT documentation for cable details.
