Quartz – Extraordinary Material for Amazing Performances Lineas is a rugged and reliable quartz sensor, distinguished by its excellent accuracy, stability and long life. It covers all speeds from walking pace to highway driving. The Lineas is the only sensor, which can be reworked in case ruts or cracks appear in the pavement. With its modular design the adaptation to the road width and surface is very easy. For the installation only a small intrusion in the road is required. Lineas is maintenance free and very safe, as it is well secured in the road (without frames or screws).
Lineas® Features the Unique Properties Offered by Quartz Force Sensors
• There is no fatigue or ageing Absolutely stable electrical and mechanical properties • Works reliably from arctic to desert temperatures Operating temperature range = –50 ... 80 °C • Temperature influence is negligible <1 % within a temperature variation of 50 °C • Uniform sensitivity over entire sensor length • Wide, linear measuring range Bikes can be weighed as accurately as heavy vehicles • Measures accurately at any speed – up to highway speed • Decoupled from lateral forces – no ghost axles appear • Elastic properties match those of road surfacing materials • Quick and easy installation – no heavy machinery required • No maintenance required • Lineas is the only sensor that can be ground flush if cracks or ruts occur in the pavement Lineas meets all your requirements for Weigh in Motion!
Lineas® Applications
Statistics • Acquires vehicle load data for traffic statistics
Overload detection • Pre-Selection: overloaded trucks are diverted from the traffic for inspection and static weighing • Weight Enforcement: the weight limits are enforced by means of high speed WIM, including video • Bridge & Construction Protection: prevents overweight vehicles from crossing a bridge of limited capacity
Toll Roads • measures vehicle weights near toll gates, i.e. for weight-dependent toll
Road Research and Pavement Management System • Gathers data for use as design criteria for road and structural engineering • Verifies optimal load distribution between axles and wheels of a vehicle • Detects excessive axle and wheel loads
Lineas meets all your requirements for Weigh in Motion
Lineas® Installation – Minimal Invasive Technology The installation of Lineas WIM sensors is fast and easy, requiring just a few steps. The intrusion in the pavement is very small: only a slot of 55 mm depth and 72 mm width. The lane is usually closed for just 6 to 8 hours and the only heavy machinery needed is a pavement cutter or milling machine.
