The MA-110 interface operates a Sensor Line fiber optic road traffic sensor responding to changes of its optical transmittance and provides respective electrical output signals that can be retrieved by other devices for traffic data processing. The unit comprises a high power infrared LED transmitter, a PIN diode photodetector, and the optical transmission analysis electronic. All of our fiber optic road traffic sensors (like PUR, PUR-B, EZ, EZR, SMS) can be directly connected to the MA-110. Also available: MA-210 and MA-310 for 2 and 3 sensors in parallel.
The MD-220 is a two-channel static opto-electronic interface for Sensor Line fiber optic road traffic sensors. Its purpose is to feed light into two of those sensors at a time, monitor the amount of light transmitted by them and detect small changes caused by pressure applied to the sensors. The interface can store the amount of light transmitted without any pressure applied for a virtually infinite time; the pressure can therefore be detected as long as it is on the sensor. All of our fiber optic road traffic sensors (like PUR, PUR-B, EZ, EZR, SMS) can be directly connected to the MD-220.
Semi-rigid two component polyurethane slot filler material with good mechanical properties and low pouring viscosity. The PUR Slot Filler is designed as slot filler material for our PUR- (and PUR-B) Sensors in asphalt roads. The PUR Slot Filler does not contain any halogen- or heavy metal components. It complies with the RoHS (2002/95/EG) and electronic waste regulation WEEE (2002/96/EG directive of the EU).
Hanger Bars are re-usable installation tools for the installation of PUR- and PUR-B Sensors. The Hanger Bars ensure the right leveling of the sensor strip to the road surface and avoid floating (when they are screwed to the street or are loaded). The Hanger Bars are clipped on the sensor strip so that it can be positioned over the opening of the road at a distance of approximately every 25-30 cm.
The Bolt Set is a road anchor for fixing frames into concrete and consists of a bolt, a washer and a snap ring. The snap ring has to be placed between the washer and the bolt head. The holes for the Bolt Set should have a 10 mm diameter and be at least 170 mm deep below the top of the frame.
Self-adhesive reinforced mastic membrane Pocket Tape with a peelable protective release film for traffic counter installations, for example 4 inch seal tape with center pocket.
