TyreShield combines
simplicity of operation with the most advanced
solid-state electronic design.
Each wheel's valve dust cap is replaced by a TyreShield
sensor which continuously monitors
the tyre pressure and reports to a computer
controlled monitor in the cab. Should the pressure in any
tyre drop by more than 12.5%, a radio signal is sent to a
display unit in the cab to warn the driver which of his
tyres is losing air by giving an audio
and visual signal.
He then has time to act before the
tyre is damaged - saving on tyre wear and fuel,
plus the expensive results of complete tyre failure.
The driver is also warned if any sensor is suffering from
low battery power, is missing or malfunctioning in any
other way. Further, if the air
temperature at road level approaches freezing
point, the system warns of possible road icing.
For articulated rigs, a radio relay unit mounted on the
front of the trailer passes messages from the trailer's
wheels to the cab's computer monitor.
TyreShield sensors work at temperatures ranging from -40°C
to +60°C, and pressures
from 140kPa to 1050kPa. They also compensate for
temperature when measuring tyre pressures to give a true
reading.
With aerials and cabling supplied, a TyreShield
system is as easy to fit as
a car radio. There is nothing extra to connect or
disconnect when changing trailer. The cab computer is
pre-programmed to accept the new set of trailer wheels,
but will not react to sensors from other rigs.
TyreShield sensors are unconditionally guranteed for
12 months: their batteries lasting
from 2.5 to 3 years.
The rest of the TyreShield equipment - being powered by
the vehicles'
electrical system - has no similar life span limitations.
