Components
Function
The external sensor, which is fastened to the existing wheel bolts, enables a wheel change without the
need to recongure the system. The external sensor is also predestined for retrotting due to the way
it is installed. Please note that special external sensor and PA tube variants must be used for different
rims and installation locations.
With twin wheels and Super Single rims, problems may occur with the radio transmission due
to the immersion depth. To ensure a good quality of reception, T-shaped external sensors
should be used (WABCO part numbers: 960 731 031 0 or 960 731 041 0).
