Fiber Optics Sensors

With its fiber optic technology, Sensor Line meets all requirements for modern traffic systems such as precise axle detection and cyclist counting. In addition to the standard accessories, Sensor Line also offers a highly flexible, high-performance classification system for road traffic.

SL PUR Sensor

The SL PUR sensor detects vehicles in road traffic for applications like axle counting, speed measurement, headway measurement, vehicle classification and cyclist counting. The SL PUR sensor is designed for permanent installation in concrete or asphalt roads. Its special T-shape ensures a fast and long-term installation.
The pressure of a wheel deforms the SL PUR sensor. This deformation decreases the optical transmittance inside the sensor. This transmittance change is detected by our opto-electronic interfaces like the dynamic or static optical transmittance analyzer and is transformed into signals for traffic data processing.

SL PUR-B Sensor

The SL PUR-B sensor is a modified SL PUR sensor for bicycle detection and cyclist counting that has a softer top layer of polyurethane-based resin than the standard SL PUR sensor. The SL PUR-B sensor is designed for permanent installation in concrete or asphalt roads. Its special T-shape ensures a fast and long-term installation.
The pressure of a bicyclewheel deforms the SL PUR-B sensor. This deformation decreases the optical transmittance inside the sensor. This transmittance change is detected by our opto-electronic interfaces like the dynamic or static optical transmittance analyzer and is transformed into signals for traffic data processing.

SL EZ Sensor

The SL EZ sensor detects vehicles in road traffic for applications like axle counting, speed measurement, headway measurement, vehicle classification and cyclist counting. The SL EZ sensor is designed for permanent installation in concrete or asphalt roads. It is a polyurethane-based reinforced fiber optic traffic sensor which is preinstalled in a frame of high density polymer and for a fast and easy replacment of the sensor stripes.
The pressure of a wheel deforms the SL EZ sensor. This deformation decreases the optical transmittance inside the sensor. This transmittance change is detected by our opto-electronic interfaces like the dynamic or static optical transmittance analyzer and is transformed into signals for traffic data processing.

SL EZR Sensor

SL SPZ Sensor

The SL SPZ sensor detects cars, trucks as well as motorbikes and bicycles (depending on the embedding material) in road traffic for axle counting, speed measurement, headway measurement, vehicle classification and cyclist counting. The SL SPZ sensor is a basic fiber optic traffic sensor designed for permanent installation in concrete or asphalt roads. The SL SPZ sensor is installed with our PU-based filler material which provides a perfect bonding to roads.
The pressure of a wheel deforms the SL SPZ sensor. This deformation decreases the optical transmittance inside the sensor. This transmittance change is detected by our opto-electronic interfaces like the dynamic or static optical transmittance analyzer and is transformed into signals for traffic data processing.

SL SMS Sensor

The surface mounted SL SMS sensor is a flat fiber optic traffic sensor designed for temporary installations in a road pocket tape (e.g. self-adhesive reinforced mastic membrane pocket tape) which is sticking on the pavement. This type of sensor allows an easy and fast installation on the road.
The pressure of a wheel deforms the SL SMS sensor. This deformation decreases the optical transmittance inside the sensor. This transmittance change is detected by our opto-electronic interfaces like our dynamic or static optical transmittance analyzer and is transformed into signals for traffic data processing. Sensitive and insensitive zones of the sensor can be defined on customer request.
