Road Traffic Monitoring. Our RoadTrax Brass Linguini (BL) axle sensors, made with our unique PVDF (piezoelectric) cable, is suited for dynamic applications such as weigh-in-motion, speed and red light cameras, and vehicle classification and counts. The Brass Linguini (BL) axle sensors are highly accurate for speed and classification, robust, low cost, easy to install, and offer a great signal-to-noise ratio.
We also offer Sensor Line fiber optic axle sensors in North and South America. Suited for toll applications, Sensor Line uses fiber optic light-based technology instead of contact closures for improved accuracy and reliability. Sensor Line sensors can be used for static or dynamic applications, with speeds from zero to highway. The sensors are compatible with existing systems and are offered in replaceable treadle formats for easy installation in most weather conditions.
Piezoelectric Traffic Sensors
The Roadtrax BL traffic sensor is designed for permanent or temporary installation into or onto the road surface for the collection of traffic data. 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.
Fiber Optic Traffic Sensors
North and South America
TE Connectivity offers various fiber optic traffic sensing solutions. The PUR fiber optics axle sensors are available for installation into asphalt or concrete roads or as a direct replacement for contact closure treadle strips. The EZ Treadle Sensor Line are TE’s most durable version of fiber optic axle sensors and are installed into a polymer frame. TE also offers a line of optical transmittance analyzers (OTA's) which are used to operate fiber optic treadles.
