Total Weigh Error Within Five Percent Weigh In Motion Sensors With Nominal Sensitivity Minus 1 Point 54 Plus Or Minus 7 Percent PC N And Durability High Resistance To Traffic Load Weather Conditions

Product Description:

The Weigh In Motion Sensors represent a cutting-edge advancement in the field of vehicle weighing technology, designed to provide accurate, reliable, and efficient measurement of dynamic axle loads as vehicles move over sensor-embedded roadways. Utilizing the unique properties of quartz sensors, these weighing sensors harness the quartz piezoelectric effect to deliver precise and consistent data critical for traffic management, toll collection, and infrastructure protection.

At the core of the Weigh In Motion Sensors lies the use of high-quality quartz sensors, which capitalize on the quartz piezoelectric effect to convert mechanical stress from moving vehicles into measurable electrical signals. This effect ensures exceptional sensitivity and durability, making the weighing sensor suitable for prolonged use in harsh environmental conditions. The nominal sensitivity of the sensors is calibrated at -1.54 ± 7% PC/N, allowing for highly accurate detection of load variations with minimal signal distortion. This sensitivity range ensures that even slight changes in axle weight are captured with precision, facilitating accurate weight measurements in real-time traffic scenarios.

One of the standout features of the Weigh In Motion Sensors is their factory calibration, which guarantees optimal performance right out of the box. Each sensor undergoes rigorous calibration processes to ensure horizontal consistency within a tight tolerance of less than ±3%. This horizontal consistency is crucial for maintaining measurement accuracy across the entire sensor surface, preventing discrepancies caused by uneven load distribution or slight misalignments during installation. Additionally, the sensors offer options for field recalibration, empowering users to maintain sensor accuracy over time without the need to remove or replace the equipment. This flexibility significantly reduces maintenance costs and downtime, ensuring long-term reliability.

Durability and environmental protection are paramount in the design of these weighing sensors. The Weigh In Motion Sensors boast an IP68 protection class, which signifies their ability to withstand continuous immersion in water and complete dust ingress protection. This robust protection class makes the sensors ideal for installation in challenging outdoor environments, including highways, bridges, and toll plazas, where exposure to moisture, dust, and other contaminants is inevitable. The sensors' insulation resistance exceeds 10GΩ, providing excellent electrical isolation and safeguarding the internal components from electrical interference and degradation. This high insulation resistance enhances the sensor's lifespan and measurement stability, even in electrically noisy environments.

The integration of quartz piezoelectric effect-based technology in the Weigh In Motion Sensors not only improves measurement precision but also offers a low-maintenance solution compared to traditional weighing methods. Unlike mechanical load cells that may suffer from wear and tear due to moving parts, quartz sensors are solid-state devices with no moving components, thereby reducing the risk of mechanical failure and the need for frequent calibration. This attribute makes the weighing sensor an economical choice for long-term deployment in traffic monitoring and enforcement applications.

In summary, the Weigh In Motion Sensors are an exceptional solution for dynamic vehicle weighing applications, combining the inherent advantages of quartz sensors with advanced calibration techniques and robust environmental protection. Their factory-calibrated accuracy, horizontal consistency of less than ±3%, and IP68 rating ensure reliable performance under diverse conditions. With a nominal sensitivity of -1.54 ± 7% PC/N and insulation resistance exceeding 10GΩ, these sensors stand out as highly sensitive and durable components capable of delivering precise weight measurements for effective traffic management and infrastructure preservation. By leveraging the quartz piezoelectric effect, these weighing sensors provide a sophisticated, low-maintenance, and highly reliable method for monitoring vehicle weights in motion, making them an indispensable tool in modern transportation systems.
