TMS consists of tire sensors and a receiver mounted to the vehicle. The sensors make accurate pressure measurements, which are transmitted to the receiver.

Sensors

Battery powered sensors are mounted in or on each wheel. These monitor the pressure of each tire and transmit this information by a low power radio signal.

TMS2 TMS10 TMS12 TMS14

rugged enclosure for fitting into the well of a wheel or as a bare PCB/battery assembly that you enclose yourself
pressure measurement range suitable for commercial vehicles
intervals between transmission to suit applications
option to transmit on change (e.g. loss) of pressure
transmits temperature of sensor
antennas for maximum transmission range or maximum robustness
battery configurations for long life or compactness
433.92MHz or 315MHz
FCC Part 15.231 certified version available
option to only transmit when pressurised
transmits while the vehicle is stationary

Receivers

The receiver is powered by the vehicle. It picks up the radio signals from the sensors and reports them using RS232. It can also keep a log of transmissions and generate alerts on conditions such as low pressure.

TMS11/TMS15

up to 4 antennae may be connected
433.92MHz or 315MHz
vehicle interface: power, alarm output, alarm reset
up to 4 antennae can be connected to ensure reliable reception from all wheels
choice of RS232 interface: simple "ASCII stream" or full "memory map" interface, which includes configurable alarm generation and memory log
use our "TMS Manager" program or connect the receiver directly to your vehicle network
