Sensor Line

It all began in 1996 with the innovative idea of company founder Fred Motzko to “detect pressure with light” and the first use of fiber optic technology in the intelligent transport sector. The applications of this technology are diverse, both in road and rail transportation/traffic sector.

Sensor Line Product Portfolio

In Use Worldwide

Since 1996, more than 70,000 systems with Sensor Line in-road sensors have been installed and operated in around 50 countries worldwide by our main target groups, system integrators for e.g. tolling solutions, automated vehicle counting/classification and many other applications. The advanced technological developments as well as the high quality and reliability of the products have made Sensor Line a global leader in the field of fiber optic traffic sensors.

Unique technology

Sensor Line products impress on the one hand with their highly developed and sophisticated design and on the other hand with their simple operation. The fiber optic traffic sensors basically consist of deformation sensors that generate a load-dependent output signal. This principle makes them absolutely immune to any kind of electromagnetic influences. The absence of mechanical components reduces maintenance requirements to an absolute minimum. The fiber optic traffic sensors from Sensor Line have a very high accuracy and are extremely reliable.
