How Speed Weigh In Motion System Nominal Sensitivity 1.54 ± 7 Percent PC N Vehicle Load Monitoring

Product Description:

The Weigh In Motion (WIM) Sensors are advanced devices designed to provide accurate and reliable vehicle weight measurements as they move over a sensing area. These sensors are essential components in modern traffic monitoring systems, toll collection infrastructure, and overload detection mechanisms. By integrating cutting-edge technology, including the quartz piezoelectric effect, these weighing sensors offer exceptional performance, even under challenging conditions.

One of the standout features of our Weigh In Motion Sensors is their impressive horizontal consistency, which is maintained within ±3%. This level of precision ensures that weight measurements remain stable and reliable across the sensor’s entire surface, minimizing errors caused by vehicle positioning. Such consistent performance is crucial for applications where accuracy directly impacts traffic management decisions, toll calculations, and vehicle compliance enforcement.

The sensors are available in three different lengths—1.5 meters, 1.75 meters, and 2 meters—to accommodate various roadway configurations and vehicle sizes. This flexibility allows for seamless integration into a wide range of traffic environments, from small urban roads to large highways. The choice of sensor length can be tailored to meet specific installation requirements, ensuring optimal data collection and system efficiency.

At the core of the Weigh In Motion Sensors lies the nominal sensitivity of -1.54 ± 7% PC/N, which reflects their ability to convert mechanical stress into electrical signals accurately. This sensitivity is achieved through the quartz piezoelectric effect, a phenomenon where quartz crystals generate an electric charge in response to mechanical pressure. Utilizing this principle, the sensors can detect minute changes in load, translating them into precise weight measurements. The quartz piezoelectric effect not only enhances sensitivity but also contributes to the sensor's durability and long-term stability.

Designed primarily for low speed weigh in motion applications, these sensors excel in scenarios where vehicles pass over the sensing area at reduced speeds. This capability is particularly beneficial for toll booths, weigh stations, and areas where traffic flow control is essential. By enabling weight measurement without requiring vehicles to stop, the sensors help maintain smooth traffic flow, reduce congestion, and improve overall operational efficiency.

The Weigh In Motion Sensors are engineered with an IP68 protection class rating, signifying their robust resistance to dust ingress and water immersion. This high level of protection guarantees reliable operation in harsh environmental conditions, including heavy rain, dust storms, and extreme temperatures. Such durability makes the sensors ideal for outdoor installations where exposure to the elements is inevitable.

In addition to traffic monitoring and toll collection, these weighing sensors play a critical role in overload detection. By accurately measuring vehicle weight in real-time, they help enforce weight limits and prevent road damage caused by overweight vehicles. This function supports infrastructure preservation and enhances road safety by ensuring compliance with transportation regulations.

Overall, the Weigh In Motion Sensors offer a comprehensive solution for accurate, efficient, and durable vehicle weight measurement. Their combination of precise horizontal consistency, customizable sensor length options, high nominal sensitivity through the quartz piezoelectric effect, and robust IP68 protection class makes them an indispensable tool in modern traffic management systems. Whether used for low speed weigh in motion applications, toll collection, or overload detection, these sensors deliver reliable performance that meets the demanding needs of today’s transportation infrastructure.
