WIM Strip Scales (Weigh-In-Motion Strip Sensors) – High-Performance Roadside Measurement

This product description presents Intercomp's high-precision, in-road Weigh-In-Motion (WIM) strip sensor systems, which have been specifically developed for traffic monitoring and roadside enforcement applications. These sensors are excellently suited for high-speed, non-intrusive measurement of vehicle axle and gross weights, ensuring efficient and accurate traffic management.

Overview and Key Features

Intercomp WIM strip sensors represent the latest technology in the field of dynamic measurement. The extremely robust, low-profile strips can be flexibly integrated into existing road surfaces, requiring minimal construction work. The sensors, based on precision strain gauge technology, guarantee reliable and repeatable measurements, even under high traffic volumes and extreme weather conditions.

These sensors are ideal for areas where rapid vehicle weight checking is essential, such as police checkpoints, highway toll systems, port, and border crossings.

Main Advantages:

High-Speed Weighing: Capable of determining vehicle weights while in motion, significantly increasing inspection capacity.
Exceptional Durability: Designed to withstand high traffic volumes, extreme temperature fluctuations, and the mechanical stress caused by heavy commercial vehicles.
Accuracy: The embedded strain gauge technology ensures a high level of measurement accuracy that complies with strict regulatory requirements.
Discrete Installation: Due to their low profile, they cause minimal traffic disruption during installation and are almost invisible to drivers.
System Compatibility: Easily integrable with Intercomp's wide range of WIM displays, data acquisition systems, and software.

Detailed Application Areas

The versatility of Intercomp WIM strip sensors enables their widespread use in traffic safety and logistics:

Roadside Enforcement and Regulation

These sensors form the basis of modern traffic monitoring systems aimed at identifying overweight vehicles and promoting compliance with regulations.

Overweight Vehicle Screening: The strips quickly identify suspiciously heavy axles or entire vehicles, which can then be directed to a static scale.
Data logging: They continuously collect traffic data, including axle load, vehicle speed, and vehicle type (identification based on axle configuration).
Ports and Gates: Ideal for monitoring the weight of incoming and outgoing traffic at logistics hubs.

Toll Systems

High-precision WIM capability is crucial for automated tolling systems where tolls are determined based on vehicle weight or axle load.

Dynamic Tolling: Enables immediate, automatic calculation of tolls without requiring the vehicle to stop.

Cooperation with Other Systems

The strip sensors can measure on their own, but they provide maximum efficiency as part of a complete WIM system, which typically consists of the following:

WIM Strip Sensors: The components that perform the physical measurement.
WIM Axle Scale (e.g.: LS-WIM®): Specialized systems optimized for low-speed weighing, which often complement strip sensors.
Displays and Indicators: Such as the TAC30™ CPU touchscreen displays, which show measurement data in real-time.
Software: Solutions for data processing and archiving (e.g.: ACWeigh™ software).

Installation Considerations

The installation of WIM strip sensors requires specialized expertise to achieve maximum accuracy.

Roadbed Preparation: A precisely designed groove must be cut into the asphalt or concrete for the strips. The surface must be flat and stable.
Calibration: After installation, the system must be calibrated using reference vehicles with known weights (e.g.: calibration trucks) so that raw sensor data is converted into accurate weight values. The system supports continuous calibration checks.
Környezeti Védelem: Protection of cables and connectors is critical to ensure a long service life.

Intercomp WIM strip sensors guarantee reliability and measurement accuracy in all road or industrial applications where dynamic weighing is essential.
