THE RADIX TRAFFIC
BELOW GROUND VEHICLE DETECTOR
RTM MAGNETOMETER COMPONENTS
Radix Sensor RTM300
 3-axis magnetometer technology monitors changes in the
Earth’s magnetic field caused by vehicles passing over it.
 The processor interprets these changes and determines
whether to indicate a detection event based on sensitivity
settings and other criteria.
 Rugged IP68 rated cylindrical housing, nominally only 18mm
diameter. Draw cord can be fitted to the housing for easy and
quick retrieval.
 2-wire connection back to RTM500 Interface Card located at
Signal Controller via new or existing loop feeder cable.
RTM MAGNETOMETER COMPONENTS
Radix Interface Card RTM500
 Standard 3U Eurocard rack mounting into
TR2512 detector backplane.
 Delivers power, signals, sensitivity and other
parameters to, and receives detection event data
from, the RTM300 sensor.
 Each RTM500 card supports connection of up
to four RTM300 sensors.
 Front panel detect & fault LEDs switch off after
a pre-determined time to save power and are
restored by a quick press of the reset button.
 User selectable front panel switches to select
sensitivities and presence times for each sensor
channel.

INSTALLATION
 The
RTM300 Sensor is installed into cross carriageway ducting.
 Ducts may be existing cable ducts at suitable road crossing points,
or dedicated narrow bore ducts located nearer the surface.
 Depending on the choice of duct diameter, it is possible to fit
multiple sensors in one duct for detection in individual lanes.
 Draw cords should be attached to each sensor to allow easy
adjustment/removal.
INSTALLATION
 The
RTM300 Sensor is connected to the RTM500 Interface Card
back inside the Traffic Controller using a 2-wire system via existing
legacy or new loop feeder cable.
 Connection to the feeder is made in the conventional manner and
the use of a re-usable bottle joint is recommended for this purpose.
INSTALLATION
 The
RTM500 Interface Card is installed into a Standard 3U
Eurocard Rack inside the Traffic Controller.
 It is the same size as a standard loop detector card and fits into
a standard TR2512 backplane.

BENEFITS OF RADIX DETECTOR vs OTHER DETECTORS
RADIX BELOW GROUND DETECTOR
OTHER BELOW GROUND DETECTORS
Cost effective & reliable over the 15 year
design life of the products, with no routine
maintenance required.
Carriageway loops & sensors are typically
replaced or repaired every 5 years
Quick & easy to install in existing ducts, no
need for Traffic Management/Lane Closures
Traffic Management/Lane Closures required
for installation
Cannot be easily damaged, as the RTM300
sensor is typically installed at a depth of
between 150mm to 600mm beneath the road
Loops and other sensors are typically installed
in the road at a depth of between 50mm to
100mm and can easily be damaged by third
parties, utilities, resurfacing etc
No batteries to change, no repeaters or other
wireless street furniture to install and maintain
High equipment cost and requires routine
maintenance and Traffic Management
SUMMARY
The Radix RTM Magnetometer Vehicle Detector offers
customers significant life cost savings over other below
ground detection solutions.
