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.
