IP68 Rated Weigh In Motion Sensors with CAN Communication Protocol and Analog

Product Description:

The Weigh In Motion (WIM) Sensors are advanced devices designed to accurately measure the weight of vehicles as they move over a specific point, providing crucial data for traffic management, vehicle classification, and enforcement of weight regulations. These sensors are constructed from high-quality aluminum (AL) material, ensuring durability and long-term reliability even in demanding environments. The robust AL construction not only offers excellent resistance to wear and corrosion but also contributes to the sensor's lightweight design, facilitating easy installation and maintenance.

One of the key technical specifications of the Weigh In Motion Sensors is their exceptionally low working current, which is less than 0.1A. This low power consumption makes the sensors highly efficient and suitable for integration into various traffic monitoring systems without imposing significant energy demands. The sensors are engineered to deliver precise axle load measurements with an accuracy of greater than or equal to ±90%. Such high accuracy is critical for applications where precise weight data is necessary to ensure compliance with legal axle load limits and to prevent road damage caused by overweight vehicles.

The dimensions of the Weigh In Motion Sensors typically vary depending on the sensor size, but a common size is approximately 300mm in length, 50mm in width, and 20mm in thickness. This compact form factor allows the sensors to be embedded within road surfaces or mounted in other configurations without causing significant disruption to traffic flow. The size versatility ensures that the sensors can be customized to meet specific project requirements, making them adaptable to a wide range of installation scenarios.

At the heart of the Weigh In Motion Sensors lies the quartz piezoelectric effect, a phenomenon whereby quartz crystals generate an electrical charge in response to mechanical stress. This quartz piezoelectric effect is harnessed within the sensor to convert the dynamic load exerted by vehicle axles into measurable electrical signals. The use of quartz ensures high sensitivity and stability over a wide temperature range, which is essential for outdoor applications subject to varying weather conditions. The nominal sensitivity of the sensors is -1.54 ± 7% picocoulombs per Newton (PC / N), reflecting their capability to detect subtle changes in load with remarkable precision.

The quartz piezoelectric effect not only provides the basis for the sensors' operation but also contributes to their longevity and consistent performance. Unlike other sensing technologies that may degrade over time, quartz-based sensors maintain their calibration and accuracy for extended periods, reducing the frequency of maintenance and recalibration. This reliability is particularly important for continuous monitoring systems deployed on busy highways and transport hubs.

In summary, the Weigh In Motion Sensors combine durable aluminum construction, low power consumption, high axle load accuracy, and compact dimensions to deliver a comprehensive solution for dynamic vehicle weighing. Their operation, grounded in the quartz piezoelectric effect, ensures precise and reliable data collection essential for modern traffic management and infrastructure protection. Whether used for enforcement, research, or infrastructure planning, these sensors represent a cutting-edge application of quartz piezoelectric technology designed to meet the demanding needs of today's transportation systems.
