Sensor Overview
The sensors use a tire pressure monitoring system (TPMS), to form a system
with the car's tire pressure receiving unit, you need to install the tire wheels (as

Instructions for use
In stationary mode, the pressure and acceleration are meas ured about every 30
second and emission of RF frames occurs only if pressure variation, higher than a
thres hold, is detected (leakage detection).
thres hold, is detected (leakage detection).
When the vehicle starts moving, the Tire Guard transmitter enters the driving
mode. Then the wheel unit measures and transmits data every 60 sec onds.
If, during any measurement period in driving mode, the pressure leakage is
detected (differenc e compared to the last transmitted pressure value), a alarm
signal will occur taking in account the latest pressure value emitted as reference
signal will occur taking in account the latest pressure value emitted as reference
value. If the pressure continues changing, an additional transmission will be sent.
