General description
WU is a sensor placed in the tire that reports pressure and temperature.
The WU is mounted inside the wheels, fixed to the valve. The angle between the valve and the housing of the WU is variable.
This allows adaptation to various types of rims.
The Wheel Unit is made of a PCB supporting the electronic
hardware and encapsulated inside a housing which is potted with
polyurethane.
It is self-powered by a battery and includes all systems for
parameter measurement (pressure, temperature and centrifugal
acceleration and optionally rotation direction), RF transmission and LF
detection.
To achieve the specified battery lifetime, the WU supports
various measurement and transmission timings, depending on WU operation
mode.
For RF transmission, WU uses an internal antenna. |
