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.
