2.1.1 Wheel module
Wheel module is cast in plastic enclosure and is
composed of:
•
pressure sensor 2-14 bars
•
electronic circuits for data procession
•
electronic circuits for data transmission
•
lithium-battery
•
24 bit identification code
Life cycle of the battery > is five years under normal
operating conditions.
Wheel module is mounted by the standard nuts from
outside to the shank to rim and is connected to valve.
Result is:
+
easy installation, tire dismounting is not necessary
+
high quality of wireless data transfer
+
Modules remain in their place even during tire
change, i.e. the system does not have to be newly
setup.
The wheel module must not disrupt wheel balance;
therefore the counter weight is mounted on the opposite
side.
Evaluation and data transfer is provided by 433 MHz
signal. If the pressure is constant, measured values are
transmitted every 15 minutes, if the pressure is changing,
frequency of data transfers is faster.
