The RoadTrax BL Piezo Traffic Sensor is available both as a Class I (weigh in motion) and Class II sensor (counting, classifying, toll booths, red lights, etc.).
The unique construction of the sensor allows direct installation into the road in a flexible format so that it can conform to the profile of the road. The flat construction of the sensor gives an inherent rejection of road noise due to road bending, adjacent lanes, and bow waves of approaching vehicles. The small cut in the road minimizes the damage done to the road, speeds up the installation and reduces the amount of grout used for the installation. The RoadTrax BL sensor is available both as a class I sensor for the highest level of uniformity needed for weigh in motion applications and as a class II sensor which is more cost effective for counting, classifying, high speed toll booths, speed detection, and red light cameras.
TE’s RoadTrax BL axle sensors are made with our unique PVDF (piezoelectric) cable for dynamic road traffic monitoring. Highly accurate for speed and classification, robust, low cost, easy to install, and offering a great signal-to-noise ratio, these sensors offer tremendous value.
