Output Impedance 10GΩ Low Speed Weigh In Motion Sensors Vehicle Weight Detection Technology for Road Safety and Infrastructure Management

Product Description:

The Weigh In Motion (WIM) Sensors are advanced measurement devices designed to accurately capture the weight of vehicles as they move over a sensor embedded in the road surface. These sensors are essential tools in traffic management, toll collection, vehicle overload control, and infrastructure protection, offering precise and reliable weight data without requiring vehicles to stop. The product is engineered to support both low speed weigh in motion and high speed weigh in motion applications, making it versatile for various traffic conditions and operational requirements.

One of the key features of these Weigh In Motion Sensors is their extremely high output impedance of 10GΩ. This high impedance ensures minimal signal loss and maximum sensitivity, allowing the sensors to detect even subtle weight variations with great accuracy. This characteristic is particularly crucial for applications involving low speed weigh in motion, where precise measurements at slower vehicle speeds are necessary to ensure data integrity and performance.

The sensors come in multiple length options — 1.5 meters, 1.75 meters, and 2 meters — providing flexibility to suit different installation environments and road types. The varying lengths allow for customization based on lane width, vehicle types, and desired measurement accuracy. Longer sensors can capture data from larger vehicles or multiple wheels, while shorter lengths might be ideal for tighter spaces or specific traffic lanes.

In terms of communication, the Weigh In Motion Sensors are equipped with versatile interfaces including RS232, RS485, and Ethernet. This range of communication protocols ensures compatibility with a wide array of data acquisition systems, control units, and traffic management platforms. Whether integrated into a legacy system via RS232 or RS485 or connected to modern networks through Ethernet, these sensors provide seamless data transmission and real-time monitoring capabilities, enhancing operational efficiency and data accessibility.

Durability and environmental resistance are paramount for sensors deployed on roadways, and these WIM sensors excel in this area with an IP68 protection grade. The IP68 rating means the sensors are completely dust-tight and capable of withstanding continuous immersion in water under specified conditions. This makes them ideal for installation in harsh outdoor environments, where they can endure exposure to dust, dirt, moisture, and even flooding without compromising performance. This robust protection ensures long-term reliability and reduces maintenance costs.

The ability to perform accurate measurements across a range of vehicle speeds means these Weigh In Motion Sensors are suitable for both low speed weigh in motion and high speed weigh in motion scenarios. For low speed weigh in motion applications, the sensors provide detailed and stable weight data as vehicles slow down or queue, supporting enforcement and control measures. Conversely, in high speed weigh in motion setups, they offer rapid and precise weight detection for vehicles traveling at highway speeds, enabling efficient traffic flow without stopping or slowing vehicles.

Overall, the Weigh In Motion Sensors combine high precision, adaptable length options, robust communication interfaces, and superior environmental protection to deliver reliable weight measurement solutions. Their capability to handle both low speed weigh in motion and high speed weigh in motion conditions makes them indispensable tools for modern transportation infrastructure and traffic management systems. Whether for toll roads, freight monitoring, or road safety enforcement, these sensors provide the accuracy, durability, and connectivity needed to meet the demands of today’s dynamic traffic environments.

This not only improves traffic flow but also helps prevent road damage caused by overloaded trucks. The sensor’s total weigh error of less than ±5% ensures that weight readings are accurate and dependable, which is crucial for enforcing weight regulations and promoting road safety.

The robust design of the HL-S-QZ70, featuring an IP68 protection class and protection grade, makes it highly resistant to harsh environmental conditions such as dust, water, and extreme temperatures. Its AL (aluminum) material construction further enhances durability, making it suitable for outdoor and industrial applications where sensors may be exposed to challenging elements. The packaging in cartons and a minimum order quantity of 4 pieces make it convenient for bulk deployment in large-scale projects.

Communication flexibility is another significant advantage of the HL-S-QZ70. With interfaces supporting RS232, RS485, and Ethernet, these weighing sensors can be easily integrated into existing data acquisition systems, allowing seamless transmission of weight data for further processing and analysis. The quick delivery time of 5-10 days and payment terms via TT facilitate efficient procurement for businesses.

In summary, the HENGLIANG HL-S-QZ70 Weigh In Motion Sensors are perfectly suited for applications requiring precise, durable, and real-time weight detection. Key scenarios include truck overload detection on highways, logistics hubs, and industrial weighing systems. Leveraging the quartz piezoelectric effect, these sensors deliver reliable performance, making them an indispensable component in modern transportation weight management solutions.
