CET8312-A
Quartz Sensor for Weigh-In-Motion (WIM)
WIM Quartz Sensor
Enviko, a leader in traffic weighing innovation, presents the
CET8312-A Quartz Sensor—a cutting-edge solution designed
specifically for Weigh-In-Motion (WIM) systems. Engineered to
deliver unmatched accuracy and durability, this sensor combines
piezoelectric technology with robust design, making it the ideal
choice for heavy-duty traffic monitoring and commercial weighing
applications. Whether deployed on highways, logistics hubs, or
industrial sites, the CET8312-A sets new standards for reliability
in dynamic weighing scenarios.
Exceptional Precision for Critical Weighing Tasks
The CET8312-A quartz sensor stands out with its remarkable linear
output, ensuring a single-sensor consistency accuracy of better
than ±1% and inter-sensor deviation below 2%. This precision is
vital for WIM systems, where real-time weight measurements must be
reliable for traffic management, toll collection, and overload
detection. Enviko’s advanced design eliminates guesswork, providing
operators with confidence in every measurement.
Robust Construction for Harsh Environments
Built to withstand the harshest conditions, this sensor boasts an
IP68 protection rating, enabling operation in temperatures ranging
from -45°C to 80°C. Its fully sealed structure prevents dust,
water, and corrosion, while the piezoelectric material ensures no
mechanical wear—ideal for long-term use in outdoor settings. The
sensor’s 40T load capacity and 150% FSO overload capability further
underscore its resilience against heavy traffic loads.
Longevity and Low Maintenance
With a design lifespan exceeding 100 million axle passes and an
MTBF (Mean Time Between Failures) of ≥30,000 hours, the CET8312-A
minimizes downtime and maintenance costs. Enviko’s rigorous
testing—including fatigue, point, and laser detection
assessments—guarantees that each sensor meets the highest quality
standards, making it a cost-effective solution for long-term WIM
deployments.
The CET8312-A leverages piezoelectric technology to convert
mechanical force into electrical signals with remarkable
sensitivity (-1.8 to -2.1pC/N). When subjected to external
pressure, the sensor’s polar surfaces generate a charge
proportional to the applied force, translated into precise weight
data via a charge amplifier. This mechanism, combined with its
EMI-resistant cable and filtering treatment, ensures noise-free
signal transmission even in high-interference environments.
Technical specifications further highlight its superiority:
- Customizable lengths from 1M to 2M for flexible installation
- Speed range of 0.5 to 200 km/h, accommodating both slow and
high-traffic scenarios
- Insulation resistance ≥10GΩ and 2500V high-voltage tolerance for
safety and stability
Enviko’s commitment to innovation extends beyond the product
itself. With comprehensive after-sales support and technical
expertise, the company ensures seamless integration and ongoing
performance optimization for your WIM system. The CET8312-A quartz
sensor isn’t just a device—it’s a reliable partner for traffic
management agencies, logistics companies, and infrastructure
operators seeking to enhance efficiency, safety, and compliance.
