Kistler is first WIM system to gain OIML certification

Kistler said it has obtained the OIML R-134 certificate for its Weigh-In-Motion (WIM) system, making it the first WIM manufacturer to have received the certification for vehicle weighing with strip sensors from 3 to 65 km/h. Since OIML R-134 is the international metrology standard for legal weighing applications, the certificate paves the way for the use of Kistler WIM systems – consisting of Lineas quartz WIM sensors and the Kistler WIM Data Logger – in applications such as weight-based toll collection

657 Kistler said it has obtained the OIML R-134 certificate for its Weigh-In-Motion (WIM) system, making it the first WIM manufacturer to have received the certification for vehicle weighing with strip sensors from 3 to 65 km/h.

Since OIML R-134 is the international metrology standard for legal weighing applications, the certificate paves the way for the use of Kistler WIM systems – consisting of Lineas quartz WIM sensors and the Kistler WIM Data Logger – in applications such as weight-based toll collection and automatic weight enforcement.

Road concessionaries and toll road operators can upgrade existing manual toll collection solutions to free-flow automatic toll collection, allowing vehicles to pass their toll collection sites without stopping.

Furthermore, governments in several countries are pushing ahead with automatic weight enforcement applications. Automatic weight enforcement aims to detect and pursue overloaded vehicles automatically by using a WIM system combined with license plate recognition. This requires a legal framework and the use of a certified WIM system. OIML provides a sound basis for creating the necessary legal framework for these applications.

Obtaining an official certification for legal weighing applications can be a lengthy and costly process. Kistler’s OIML-certified WIM systems can help to accelerate the approval process.

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.

    There are interesting moves afoot to create Germany’s first Weigh-In-Motion enforcement site in Hamburg – but Florian Weiss of Traffic Data Systems warns that WIM certification is a complex business. In the past, Weigh-In-Motion (WIM) was mainly used for statistical (WIM-S) and pre-selection (WIM-P) applications. These abbreviations - as well as WIM-E (enforcement) and WIM-T (tolling) - were created by Traffic Data Systems during Intertraffic 2006 in Amsterdam. This was also the year when we started the

Kistler, a measurement technology company, says its KiTraffic system is being used to track and fine overloaded trucks on the D7 Highway from Prague to the north-west of the country. KiTraffic is comprised of Lineas brand quartz sensors integrated into the road, cameras, hardware and software. If a truck exceeds the weight limit, the system sends the weight and a photograph
