Sensor Line

Everything began in 1996 with the innovative idea of company founder Fred Motzko "to detect pressure by light" and the first use of fiber optic technology in traffic applications. The applications of this technology are diverse, in road traffic as well as in the rail traffic sector.

Worldwide in use

Over 40,000 systems have been successfully installed in about 50 countries worldwide since 1996. The progressive technological developments as well as the high quality and reliability of the products have made Sensor Line a global market leader in the field of fiber optic traffic sensors.

Unique technology

Sensor Line products impress on the one hand by their complex structure and on the other hand by the easy operation. In principle, the fiber optic traffic sensors consist of deformation sensors which generate a load-dependent output signal. This principle makes them absolutely immune to any kind of electromagnetic influences. The absence of mechanical components reduce maintenance to an absolute minimum. Sensor Line’s fiber optic traffic sensors have a very high accuracy and are outstandingly reliable.
