Kistler Lineas strip sensors receive OIML certification

Kistler has announced that its Weigh-In-Motion (WIM) system consisting of Lineas quartz WIM sensors and the Kistler WIM Data Logger has been OIML R-134 certified. Kistler said its WIM system precisely measure axle loads and vehicle weights from low to high speed. It is now, with the OIML certificate (International Organisation of Legal Meteorology) also certified for legal applications from low to medium speed (3-65 kph) with accuracy class 5 and class 10.

657 Kistler has announced that its Weigh-In-Motion (WIM) system consisting of Lineas quartz WIM sensors and the Kistler WIM Data Logger has been OIML R-134 certified.

Kistler said its WIM system precisely measure axle loads and vehicle weights from low to high speed. It is now, with the OIML certificate (International Organisation of Legal Meteorology) also certified for legal applications from low to medium speed (3-65 kph) with accuracy class 5 and class 10.

This enables the automatic collection of weight-based toll fees without stopping vehicles at the booth. Operators and concessionaries can simply upgrade their manual toll collection system to Electronic Toll Collection (ETC), allowing vehicles to pass their toll collection sites without delay.

WIM systems have served as pre-selection tools for weight enforcement and have delivered valuable traffic data. But traditional WIM systems can’t be used for legal weighing applications, such as weight-based toll collection and automatic weight enforcement.

As more and more road concessionaries and toll road operators wish to perform financial transactions – tolling - and governments push to implement automatic enforcement applications based on vehicle weight data, there has been an increasing demand for certified WIM systems, accredited according to international standards.

This certificate states that Kistler WIM systems based on maintenance-free Lineas quartz WIM sensors and the Kistler WIM Data Logger can be used for legal weighing applications.

Kistler also noted that governments in several countries are pushing for automatic weight enforcement applications. “OIML provides a sound basis for creating the necessary legal framework for these applications,” the company said. “Kistler’s OIML-certified, maintenance-free WIM systems are based on extremely durable quartz crystal sensors and can be integrated into any manual or automated weighing system.”

Other possible applications include not only toll collection and weight enforcement, but also for example weighing at ports, logistics terminals, and industrial or mining facilities. Thanks to the use of extremely durable quartz crystal sensors, Kistler’s WIM systems are maintenance-free, durable under any weather conditions and can be integrated into any overall solution both for low and high speeds.

    Taiwan’s 900 kilometres of toll roads will transition to all-electronic free flow operations early next year. The roads, which include three north-south routes with 22 toll points, carry out around 1.7 million transactions a day, generating some US$700 million of annual toll revenue. Private contractor Far Eastern Electronic Toll Collection Company (FETC), under contract to the National Freeway Bureau to collect the tolls, says that the IR-based toll system worked well and some 43 per cent of transactio

    Vendeka is here at the ITS World Congress to highlight the free flow tolling system it is applying on Turkey’s highways. The system supports 2–5 axles vehicle classes at speeds of up to 195 km/h across up to six lanes. The system can also cope with low speed vehicle passes, clusters, short distance tailgating, and it also works on emergency lanes. Indeed, Vendeka reports that the system can get accurate results about lane changing and merging while multi-lane traffic flow can be detected.
