IP68 Protection Class High Speed Weigh In Motion Technology Offering and Durable Traffic Weight Measurement Capabilities

Product Description:

The Weigh In Motion (WIM) Sensors are advanced devices designed to accurately measure the weight of vehicles, particularly trucks, as they move over a sensor embedded in the road surface. These sensors are essential tools for truck overload detect applications, helping authorities and logistics companies monitor and manage vehicle loads efficiently and safely. Utilizing the quartz piezoelectric effect, the WIM sensors convert mechanical stress from passing vehicles into electrical signals, enabling precise weight measurements without requiring vehicles to stop.

One of the standout features of these Weigh In Motion Sensors is their exceptional service life. Engineered to endure the rigors of constant traffic, they boast a service life of at least 100 million axis times. This means the sensors can reliably function through an extensive number of vehicle passes, making them highly cost-effective and dependable for long-term deployment on highways, bridges, toll plazas, and weigh stations.

The nominal sensitivity of the sensors is -1.54 ± 7% PC/N, indicating their high responsiveness to pressure changes caused by vehicle axle loads. This sensitivity level ensures that even slight variations in axle weight are detected accurately, which is critical for the precise assessment of truck weights. The use of quartz piezoelectric materials enhances this sensitivity, as quartz crystals generate a stable and consistent electrical charge under mechanical stress, allowing the sensor to deliver reliable data under varied conditions.

Accuracy is paramount in any weigh-in-motion system, and these sensors deliver with a total weigh error of less than or equal to ±5%. This low error margin ensures that the weight readings are dependable enough for enforcement and regulatory purposes, reducing the chances of false positives or negatives in truck overload detect scenarios. Moreover, the horizontal consistency of the sensor readings is maintained within ±3%, which means that weight measurements remain stable regardless of the vehicle’s position on the sensor. This consistency is vital for ensuring fairness and precision in weighing operations.

Durability is another critical aspect of the Weigh In Motion Sensors. They are built to withstand high resistance to traffic load and harsh weather conditions. The sensors are constructed from robust materials that can endure continuous heavy axle loads from trucks, as well as extreme temperature fluctuations, moisture, and other environmental factors. This durability ensures that the sensors maintain their accuracy and functionality over time without frequent maintenance or replacement, making them ideal for outdoor installations where reliability is crucial.

In truck overload detect applications, these WIM sensors provide invaluable data that helps avoid road damage and enhances traffic safety. By identifying overweight trucks in real-time, authorities can enforce load regulations more effectively, preventing excessive wear and tear on road infrastructure and reducing the risk of accidents caused by overloaded vehicles. The integration of quartz piezoelectric effect technology not only improves measurement accuracy but also contributes to the sensor’s longevity and resilience.

Overall, the Weigh In Motion Sensors represent a sophisticated solution for modern transportation management. Their combination of long service life, high sensitivity, low weigh error, consistent horizontal performance, and superior durability makes them well-suited for continuous use in truck overload detect systems. Whether deployed on highways, bridges, or industrial sites, these sensors provide accurate, reliable, and timely weight data that supports infrastructure protection and regulatory compliance.
