Weigh-In-Motion (WIM), is a technology used to measure the weight of vehicles in real-time while they are in motion. Unlike traditional static weighing, where vehicles need to come to a complete stop for weighing, WIM systems allow vehicles to pass over the weighing equipment at normal driving speeds, automatically recording their weight data.


How Weigh-In-Motion (WIM) Works

WIM systems typically use sensors (such as quartz sensors or piezoelectric sensors) installed beneath the road surface to detect pressure changes as vehicles pass over them. The sensors convert pressure signals into electrical signals, which are then processed to calculate the vehicle's weight, axle load, speed, and other information. This data can be transmitted in real-time to monitoring centers for traffic management, law enforcement, or data analysis.

The CET8312-A dynamic Quartz Sensor is a high-performance product designed by Enviko for the traffic weighing industry, offering outstanding precision and durability. With excellent linear output, the consistency accuracy of a single sensor is better than ±1%, and the deviation between sensors is less than 2%, ensuring high stability and accuracy during the Weigh-In-Motion (WIM) process.  

This Quartz Sensor features a 40T load capacity and an overload capacity of 150% FSO, meeting the demands of heavy traffic loads. It operates in temperatures ranging from -45°C to 80°C, with an IP68 protection level, adapting to various harsh environments. The design lifespan exceeds 100 million axle passes. Additionally, the insulation resistance is higher than 10GΩ and can withstand a high-voltage test of 2500V, ensuring long-term stable performance.

Improved Installation Scheme for Piezoelectric Quartz Weighing Sensors on Asphalt Pavement

Image
  1. Background Technology   Currently, WIM systems based on piezoelectric quartz weighing sensors are widely used in projects such as overload monitoring for bridges and culverts, non-site overload enforcement for highway freight vehicles, and technological overload control. However, to ensure accuracy and service life, such projects require cement concrete pavement reconstruction for the piezoelectric quartz weighing sensor installation area with the current technology level. But in some application environments, such as bridge decks or urban trunk roads with heavy traffic pressure (where the cement curing time is too long, making long-term road closures difficult), such projects are difficult to implement.   The reason piezoelectric quartz weighing sensors cannot be directly installed on flexible pavement is: As shown in Figure 1, when the wheel (especially under heavy load) travels on the flexible pavement, the road surface will have a relatively large subsidence.
