Medium-Speed
Weigh-in-Motion (MSWIM)
Measures vehicle weight while vehicles move at controlled speeds.
They offer high efficiency, accuracy, and reliability for
modern traffic environments.
What is a Medium-Speed Weigh-in-Motion System?
An intelligent weighing solution that measures vehicle weight without stopping the vehicle. Unlike traditional weighbridges, trucks do not need to halt completely. Instead, they move smoothly over embedded sensors.
As a result, this system removes the common “stop-and-go” problem. Hence improves traffic flow and increases operational efficiency.
Therefore such systems are widely used on highways, toll plazas, and industrial sites, because provide real-time data, which is essential for monitoring and enforcement.
Typically, automated vehicle weighing systems operate between 10 km/h and 60 km/h. As a result, they offer a strong balance between speed and accuracy. In addition, they meet the standards recommended by the National Highways Authority of India.
How Does MSWIM Work?
MSWIM systems use high-precision sensors installed beneath the road surface which detect weight as vehicles pass over them.
Because vehicles do not stop, the process remains smooth and continuous.
Step-by-Step Process:
- Initial Detection:
As soon as the tires pass over the sensors, the system captures axle loads in real time. - Data Transmission:
Next, the sensors send signals to a controller and the controller calculates the total vehicle weight. - Data Recording:
At the same time, the system records speed, axle count, and vehicle type. - Final Processing:
Finally, the software processes the data and displays instant results. As a result, delays are reduced and traffic congestion is minimized.
Components of a Medium-Speed Weigh-in-Motion System
A Medium-Speed Weigh-in-Motion (MSWIM) system consists of several advanced components that work together to provide accurate vehicle weight measurement and traffic monitoring.
Medium-Speed Weigh-in-Motion Load Cell
The load cell is one of the most critical components of the system. It captures axle loads and vehicle weight data with high precision. As a trusted Medium-Speed Weigh-in-Motion Load Cell supplier and exporter, we provide reliable weighing solutions for highways, toll plazas, logistics hubs, and industrial facilities.
Medium-Speed Weigh-in-Motion Indicator
The weight indicator processes signals received from sensors and load cells and converts them into accurate weight data. Our Medium-Speed Weigh-in-Motion Indicators are designed for real-time monitoring, reporting, and seamless software integration.
Medium-Speed Weigh-in-Motion Junction Box
The junction box acts as the communication interface between load cells and the indicator. Our durable Medium-Speed Weigh-in-Motion Junction Boxes ensure stable signal transmission and long-term performance in outdoor environments.
Medium-Speed Weigh-in-Motion Vehicle Separator Sensor
Vehicle separator sensors accurately detect vehicle entry and exit points. These sensors help improve axle counting accuracy, vehicle classification, and traffic analysis. We offer reliable Medium-Speed Weigh-in-Motion Vehicle Separator Sensors for demanding applications.
Bending Plate Weigh-in-Motion Technology
Modern MSWIM systems can utilize advanced Bending Plate Weigh-in-Motion technology to achieve highly accurate dynamic vehicle weighing. Bending plate sensors measure wheel and axle loads as vehicles travel at medium speeds, making them suitable for toll plazas, highway monitoring, overload enforcement, and intelligent transportation systems.
As an experienced Bending Plate Weigh-in-Motion manufacturer and exporter, Nagarjun Technovision delivers robust and reliable solutions designed for long-term performance and accuracy.
Key Features of MSWIM System
MSWIM systems offer several important features for modern logistics:
