Sensor Line technology
A brilliant idea with
endless possibilities
Rail Traffic Applications
With its unique fiber optic technology (SL FORPS), Sensor Line offers analysis systems, with sensors and electronics, for a wide range of applications in the railroad sector. The complex design of the high-precision sensors ensures reliable measurements without electromagnetic interference. All of these applications can be implemented with one sensor! In addition, there are many more that we have not even thought of yet, which are based on the measurement and evaluation of a vertical impact on the sensors.
Flat Wheel Detection
Wheels on rail vehicles are exposed to extreme stress and high loads. Defects, such as flat spots, lead to increased noise pollution and vibration and consequently to higher maintenance costs. With the use of SENSOR LINE's fiber optic sensors (SL FORPS) and electronics, signs of wear can be detected immediately. Damage to rail vehicles and tracks as well as the increased risk of derailment due to wheel damage are reduced to a minimum.

Weigh in Motion (WIM)
With the help of SL FORPS technology and the learning and intelligent algorithms of our qualified system integration partners, a measuring accuracy of +/- 3% is possible when weighing trains in motion. Together with other functionalities such as measuring speed, vibrations or flat wheels, this allows conclusions to be drawn about the actual load and impact on the infrastructure and the moving inventory. This is a basis for predictive maintenance and the avoidance of costly and sudden material failures and downtime.

Axle & Wagon Counting/Train length
Knowing who uses rail infrastructure and in what way is essential when evaluating and estimating the actual load and impact on the infrastructure and the moving stock. Auto-ID technologies can only detect when something is labelled accordingly. The Sensor Line SL FORPS technology recognizes completely independently of what is actually moving on the track. Qualified system integrators often use various methods of sensor technologies and identification. Only with SL FORPS technology can comprehensive and complete data collection be achieved.

Track Bed Analysis
The stress and condition of the ballast and track bed are decisive factors for the durability, availability and, above all, the safety of track systems. Damage to the track can have serious consequences. Sensor Line's unique fibre optic technology (SL FORPS) is able to measure the smallest changes in indirect forces on the track, e.g. caused by one-sided loads. Long-term measurements detect these damages at an early stage and can thus reduce most risks and protect the infrastructure.

Vibration Analysis
Sensor Line offers a technological solution that is insensitive to electromagnetic interference and is ideal for detecting shocks/vibrations. The installation of the fiber optic rail pad sensors (SL FORPS) between rail and sleeper ensures reliable and precise measurement. An analysis of the vibrations forms a basis for predictive maintenance and leads to a reduction in operating costs.

Speed Measurement
Sensor Line technology is one of the most reliable methods for measuring speeds. The faster a train is moving, the greater the impact of vibrations on the railroad infrastructure and moving stock. Especially if a train is traveling faster than permitted. This has a much greater immediate impact on the railroad line, the tracks, the track bed and the vehicle itself. This must be avoided at all costs in order to avoid high subsequent maintenance and repair costs. Evaluating the speed can also be an aid in narrowing down potential perpetrators in the event of damage and accidents.

Direction Detection
It may sound strange at first glance. The correct direction of travel of a train is also essential for rail safety. Knowing in which direction a train is allowed to travel and is actually moving can prevent disasters. The fact that the Sensor Line Fibre Optic Rail Pad Sensors (SL FORPS) provide this data and information “on the side” demonstrates the exceptional flexibility and universal applicability of these products and technology with the raw data they supply.
