I. TPMS1209T02-ER, FULL-TIME DIRECT TPMS
TPMS1209T02-ER is direct tire pressure monitoring system for trucks
which includes 1 monitor, 1 standard booster and 2 to 38 transmitters and
it can support monitoring of up to 38 tires. The transmitter can be
screwed onto the tire instead of the valve cap and then senses the pressure
inside the tire all the time and transmits the pressure information data to
the booster by RF technology. Then the booster transmits the pressure
information data to the monitor after received and magnified it. The
monitor can receive and deal with the data, then display the pressure on
the screen. The monitor can issue different alarms if the tire pressure is at
an improper level based on the standard pressure, so as to notify the
driver to treat the problem and avoid tire busting or tire damage.
Through TPMS1209T02-ER, the driver can keep the tire running under a
proper pressure so as to avoid excess gasoline consumption and keep the
vehicle in an easily controlled state.
