LS-WIM Series: Low Speed Weigh-In-Motion Weighing Systems
The LS-WIM (Low Speed Weigh-In-Motion) platform scale systems are advanced solutions from the Intercomp group of companies, specifically designed for the high-precision determination of vehicle low-speed in-motion axle and axle group loads, as well as gross vehicle weight. These systems are ideal for highway enforcement, weight restriction enforcement, tolling, and traffic counting applications where fast and accurate measurement is critical.
LS-WIM platform scales combine the flexibility of traditional static weighing with the speed of in-motion measurement, minimizing traffic disruption.
Key Features and Advantages
The robust design and sophisticated weighing technology of the LS-WIM systems ensure reliable performance even in the most demanding environments.
- High Accuracy at Low Speed: The system provides excellent accuracy when vehicles pass slowly over the weighing surface (typically below 10-15 km/h). This is ideal for enforcement checks where precision is essential.
- Fast Setup and Commissioning: Thanks to the platform design, installation is fast and simple, ideal for setting up temporary or mobile inspection points.
- Robust Construction: The weighing platforms are constructed from durable materials that resist heavy loads and harsh weather conditions, ensuring a long service life.
- Integrated Software Solutions: Compatible with Intercomp's advanced displays and software, enabling data logging, analysis, and reporting (including axle load, axle group load, and gross vehicle weight measurement).
- Versatile Application: Ideally used in road traffic supervision, port/gate inspections, and tolling systems.

Application Areas
LS-WIM platform scales offer a wide range of applications in the field of weight-based regulation and enforcement:
ITS / Authority Enforcement
These in-ground systems provide continuous traffic monitoring at permanent or semi-permanent enforcement sites.
- Identification of Overweight Vehicles: Effectively screens overweight commercial vehicles, reducing road network damage and increasing traffic safety.
- Data Collection and Traffic Statistics: Provision of accurate data on traffic composition and weight distribution, which is essential for transportation development planning.
- Ports and Gates: Fast weight checking at loading and unloading points to optimize logistical processes.
Portable WIM Solutions (LS630-WIM™)
Although the focus is on the built-in systems, the LS-WIM category also includes portable low-speed WIM solutions (such as the LS630-WIM™), offering flexibility:
- Temporary Inspection Stations: Quickly deployable and removable systems that can be used during temporary traffic restrictions or special inspection campaigns.
- Mobile Technical Inspection: Enables authorities to weigh vehicles anywhere without having to divert them onto a static scale.
Technological Advantages
Intercomp LS-WIM systems are the result of precise engineering work, applying the most modern sensor technology:
- Sensor Integration: High-capacity load cells integrated into the platforms ensure accurate transfer of the load to the signal processing unit.
- Signal Conditioning: The built-in electronics filter out noise and compensate for temperature variations, guaranteeing a stable measurement signal.
- Speed Compensation: A crucial element of WIM systems is speed measurement and dynamic load correction. LS-WIM systems minimize dynamic effects at low speeds, thus producing results close to static weighing.
System Peripherals and Software
The LS-WIM platforms form a complete value measurement system when paired with Intercomp displays and software:
- Indicators and Displays: Dedicated displays (e.g.: TAC30™ CPU) provide a touchscreen interface for quick data entry, display of measurements, and user interaction.
- Data Handling: The software enables automatic detection of axle configurations (e.g.: 2-axle, 3-axle trucks), setting of overweight alarms, and archiving of the complete measurement log.
- Calibration Tools: Calibration test stands and procedures are available to maintain the accuracy of the system, ensuring regulatory compliance.
The LS-WIM series is the ideal choice for any agency seeking a reliable, high-performance, and fast weight measurement solution for monitoring road traffic.
