TE CONNECTIVITY SENSORSQL WEIGH-IN-MOTIONSENSOR FOR ​ACCURATE AND
STABLE TRAFFIC MONITORINGThe Quartz QL Weigh-in-Motion (WIM) sensor from TE Connectivity (TE) is our latest innovation intraffic sensing developed with long-standing experience from our BL RoadTrax traffic sensor.
Designed for installation in most road types, the QL WIM can provide accurate weighing datafor gross vehicle weights and individual axle loads over a wide range of speed, weights andtemperatures. The robust mechanical structure of the QL WIM minimizes the disruption of theroad for installation while still providing long-term performance. The use of Piezoelectric Quartz
sensing elements allows for essentially no variation in sensitivity with temperature and enables
measurements over a wide range of speed. With a highly efficient manufacturing process TE is able
to offer the QL sensor as a cost-effective solution for weighing applications. The QL is compatible
with many commercially available WIM systems already on the market today.

The QL WIM sensor is installed into the road in a relatively small slot. Backfilled with resin, the QL
is then ready to provide WIM data over a range of speeds, vehicle types, and weather conditions.
It can provide a constant flow of information on the traffic on highways and secondary roads. Thisdata is then integrated into existing traffic monitoring systems, for Intelligent transporation systemapplications, planning and maintenance, road design and traffic safety. The QL is designed for COST
323 B(10) and ASTM 1318-09 Type III applications with a two sensor installation, higher accuracy may
be achieved using multiple sensors.

• ROBUST MECHANICAL STRUCTURE• MEASUREMENT UNIFORMITY​• QUARTZ SENSING TECHNOLOGY​• LOW TEMPERATURE COEFFCIENT

SIGNALVERSATILITY• Negative signal for compression with tire force. Consistent withmost Piezo WIM systems.

• Can be installed in a variety of pavements, including portland
cement (Concrete) and asphalt.

• High sensitivity charge output gives a good dynamic range.

• Available in different lengths to address different lane widths,
as well as with different cable lengths.

• Able to weigh and classify vehicles from motorcycles and small
cars to the heaviest trucks.
• High immunity to off-axis forces for improved accuracy.

QUALITY• 100% tested for sensitivity along the length, insulation
resistance, and capacitance.
• Results are computerized and saved.
• Sensors are serialized for traceability.
• Manufactured in an ISO 9001:2015 facility.

RELIABILITY• Mechanical design of the sensor untilized FEA of all materials used toensure design and fatigue limits.

• Typically only half-lane width. Depending on the application and the accuracy
needed, multiple sensors are installed. Normal installations will range from
2 sensors in an array up to 8 or even 16 sensors for high accuracy systems.

DURABILITY• Designed for years of maintenance-free service.
• Typically, no maintenance is needed other than normal annual calibration of
the overall WIM system.
