Vehicle weighing
solutions for any situation
sensor. Installations with these
sensors are used in a variety
of applications including data
collection, mainline
enforcement, tolling, and
industrial applications at both
low and high speeds. Installed
and grouted in place into 3in
(75mm) channels cut into the
pavement, installation takes a
single day with minimal civil
works to place sensors into
WIM systems.
Certified to OIML R134
performance standards, the
strip sensors measure wheel,
axle, and gross vehicle weights
along with axle spacing and
speeds. This data is used to
classify vehicles by axle spacing,
or to apply weight limits for
axles, axle groups, and gross
vehicle weight for screening
for overloaded vehicles. These
vehicles can then be identified,
ticketed, or diverted off the
the manufacturing headquarters
and offices throughout the
world, they provide fixed, inground
WIM scales and sensors
capable of gathering vehicle
weights at low (3km/h) to high
speeds (>120km/h). In addition,
Intercomp builds scales with
static or low-speed WIM
capabilities, thereby providing
portable or fixed certified scales
to help comply with almost any
application and regional
standard.
Fixed, in-ground sensors
Static truck scales with strain
gauge load cell technology is
widely recognized as a highly
accurate means of weighing
vehicles. A weight from these
scales is commonly used for
calibration and evaluation of
the performance of WIM sites.
Leveraging this performance
by incorporating the technology
into their fixed and portable
scales and sensors, Intercomp
produces fixed and portable
WIM products based on strain
gauge load sensors.
Perhaps the most versatile
of fixed sensors is the WIM strip
Acquiring the accurate
vehicle weight is useful
for a variety of
applications, ranging from data
collection, pre-screening and
direct weight enforcement
efforts, tolling, and industrial
check weighing. To meet local
requirements, operations can
be via employing portable scales,
or fixed, in-ground or aboveground
scales. Depending on the
purpose of gathering the weight
data, a combination of scales
may be used, with Weigh-In-
Motion (WIM) sensors used
at high speeds, and either lowspeed
WIM or static weighing
at slower speeds. For deployable
weigh stations, the use of
portable WIM scales or static
weighing allows for rapid,
temporary screening where
static weigh stations are
impractical, or do not exist.
As one can see, there are many
reasons and ways to weigh
a vehicle.
Unique among providers
of vehicle scales, Intercomp
manufactures a wide range
of both portable and in-ground
scales and sensors at their main
facility in the United States. From
roadway to protect infrastructure
such as highways and bridges.
At low speeds, these accurate
sensors are used for industrial
screening, monitoring inbound
and outbound vehicle traffic
for yards and ports, detecting
overloaded conditions, or
measuring net weights of
containers and cargo for
comparisons to Bills of
Lading (BOL).
Portable scales
Adding a new low profile
set of scales to their suite of
portable weighing products,
Intercomp has released their
LS788-WIM scales for sale. A
‘relative’ of their LP788 lowprofile
portable wheel load scale
for static weighing, the LS788
has a larger weighing platform
and ramps for WIM and static
use. Both scales demonstrate
the next generation in wheel
