The AMTAB self-developed dynamic rail scale not only provides in-motion mass measurement. The sensor and software layer also enables data collection that supports maintenance, logistics, and operational decisions.
Installation and commissioning typically within 3 working days takes place, without infrastructure modification and without traffic disruption. The system fits all standard rails, with certified sensors, across a wide speed range.
15-year warranty
1–140 km/h speed
90,000 hours of operational reliability
A calibration certificate verifies the sensors' accuracy better than 0.1% 3-30 t/axle range, -25 and +40°C ambient temperature (OIML R 106).
Wide operating range 1–140 km/h range. Designed for operational safety, MTTR < 1 hour with average repair time, MTBF > 90,000 hours with operational reliability.
Installation on standard rail, shock-resistant sensors for all climatic conditions. 15-year system operation warranty to reduce operational risk.
The system design allows installation without track construction, and without stopping traffic. The goal is for the measurement to quickly yield usable data.
On-site survey
Based on the track type, speed range, and operational goal, we determine the sensorization and data connection.
Installation on standard rail
No modification of the existing infrastructure is required, implementation can be planned without traffic disruption.
Commissioning within 3 working days
Validation, system handover, coordination of integration points.
The primary function of AMTAB WIM is the dynamic measurement of railway fittings. However, the system design is also suitable for collecting further operational information, which allows for better planning of logistics and maintenance.
Wagon, axle, and wheel-level weight data in motion
Integrated wagon classification function
Wheel defect detection (WDD) and warning of increased derailment risk
Data integration capability to superior and parallel systems with MySQL database structure
Besides measuring axle loads, the AMTAB WIM is capable of detecting damaged wheels and issuing warnings for increased derailment risks. Above 35 km/h the system is particularly effective because it detects multiple irregularities as dynamic forces.

AMTAB installed more than just a weighbridge here: connected the weighing system with the Deutsche Bahn wagon identification solution and IMERYS's own logistics processes. The goal was for the measurement to become operational, system-level data in daily operation, not an isolated measuring point.
Lesson learned: it is most useful when WIM data, linked to an identifiable wagon, arrives integrated into the logistics system.
In 2008, AMTAB installed 15 systems on a nationwide network, even in very cold and very hot climatic zones. The essence of the described example is long-term operation: the systems have been running for years,, and based on the positive experience, IRW also considered further expansion.
Lesson learned: For dynamic scales, the crucial value is durability and operational reliability — even in extreme environments.
