Vehicle Induction loop presence detectors
are designed upon the principle of the change
of inductance in a coil whose electromagnetic
field is interrupted by a metallic object.
The coil is represented by special cable
loops embedded in the roadway whose inductance
is altered when crossed over by a vehicle.
All our induction loop detectors are micro
processor based, digital types of the most
modern specification, proven reliability,
with a large margin for movement & roadway
settlement, plus good sensitivity to detect
a wide variety of vehicle sizes.
All detectors are self tuning. Detection
may be by vehicle presence, a pulse impulse
(crossing or leaving the controlled area)
or with delay before impulse. Our induction
loop detectors are an obvious answer where
vehicular only access is required automatically
& is nearly always incorporated in automatic
gate or barrier projects Utilising our range
of traffic management measures.
The majority of our induction loops are
used for safety, delaying the closing cycle
of controlled gates or barriers until the
area is clear of vehicles, pedestrian safety
is monitored by infrared line of sight beams.
We are committed to installing all types
of automatic vehicle detection loops, the
entire package is installed by our trained
A fact that demonstrates our commitment
is that we are fully equipped to install
induction loops correctly 1st time, without
the need to employ outside specialist contractors.
