Sensors & Measurement systems for trains, trams & subways

We offer a wide range of innovative measurement systems for trains, trams, subways and the hyperloop. We have developed our products together with our customers and partners. All our measurement systems are based on laser measurement technology and measure both rails and wheels. Where in the past a lot of time and labor were needed for measurements on rail and vehicles, our high-tech tools complete accurate measurements within a few seconds.

Weighing in Motion System (AWIM)

The Weighing in Motion System is a stationary measuring system in the form of a dynamic scale. It is used, among other things, for weighing while driving, detecting wheel faults and for train detection. When all measurements are combined, an overall accuracy of better than ±0.5% is achieved for trains with different speeds (corresponds to OIML R106, class 0.5).

Integrated RFiD scanning system
For identification, locomotive and wagon type are determined via an integrated algorithm for comparing the distances between passing wheels and bogies. The identification of vehicles and axles can be improved by adding additional functions. For this purpose, we offer an integrated RFiD scanning system and Vision Technology cameras to capture the vehicle number and axle identification

Things to consider about sensor solutions ans measurement systems for railway

From ensuring passenger safety to optimizing performance, the selection of sensor solutions and measurement systems plays a crucial role. At Althen Sensors & Controls, we understand the intricate requirements of the rail industry and offer tailored solutions to meet these challenges head-on. Some factors for you to consider:

Environmental conditions: Railway and tram systems operate in diverse environments, from urban settings to remote landscapes. Considerations such as temperature variations, humidity levels, vibrations, and exposure to dust and debris must be factored in when selecting sensor solutions. Robust sensors capable of withstanding harsh conditions ensure consistent performance and longevity.
Accuracy and precision: Accurate data is essential for maintaining operational efficiency and safety in railway and tram networks. Sensors must deliver precise measurements to monitor parameters such as speed, displacement, pressure, and temperature. High-accuracy sensors enhance the reliability of control systems, allowing for precise adjustments and predictive maintenance.
Reliability and durability: Railway and tram systems operate round the clock, facing rigorous demands and high uptime requirements. Sensor solutions must be reliable and durable to withstand constant usage without compromising performance. Components with long lifespans and minimal maintenance requirements are essential for minimizing downtime and operational disruptions.
Integration and compatibility: Seamless integration with existing infrastructure and control systems is critical for the successful implementation of sensor solutions in railway and tram networks. Compatibility with industry-standard communication protocols and interfaces facilitates data exchange and interoperability across various subsystems. Flexible sensor configurations enable easy retrofitting and future expansion, ensuring scalability and adaptability to evolving needs.

At Althen Sensors & Controls, we specialize in providing customized sensor solutions tailored to the specific requirements of the rail industry. Our extensive portfolio of high-quality sensors, combined with industry expertise, ensures seamless integration and optimal performance in railway and tram networks, contributing to enhanced safety, efficiency, and reliability.
