Kistler's 9835A Weigh in Motion (WiM) system has been certified for the measurement of different trucks travelling up to 120 km/h and vans up to 140 km/h.

Kistler says the WiM solutions in its KiTraffic series deliver an automated solution for monitoring traffic and protecting roads against damage by overloaded vehicles. 

Lineas sensors integrated in the road surface are expected to measure gross vehicle weight and axle loads, with measurement data available in real-time.

The Czech Metrology Institute – a  member of the International Organisation of Legal Metrology (OIML) – issued the certificate.

Kistler says OIML certificates are generally acknowledged as proof of the excellence of measuring equipment. 

Tomas Pospisek, global market development manager for road & traffic at Kistler, says: “Every country applies its own regulations for direct enforcement, but the OIML standard can be viewed as a common starting-point for local legislation.” 

Several hundred test runs were completed with vehicles of different types (5-axle, 4-axle, 2-axle and vans), either in loaded or unloaded condition and at varying speeds of up to 140 km/h.

“We met the requirements of accuracy class F10 for all vehicle types at all speeds – but that's not all,” Pospisek continues. “We actually achieved this result with only two rows of Lineas sensors.”

According to Kistler, the WiM solution can handle very high axle loads up to 30 tonnes each and there is no overall limitation on maximum measurable weight.

Lineas quartz sensors can operate at temperatures ranging from –40 to +80°C, the company adds.

    Renault's flagship Espace minivan released toxic diesel emissions 25 times over legal limits in a Swiss study, despite complying with EU tests carried out at unrealistically low engine temperatures, a German environmental group said this week. According to Reuters, the tests commissioned by the DUH group, which have not been independently verified, follow Volkswagen's admission that it used illegal ‘defeat devices’ to cheat diesel emission regulations.

Since the VW emissions story broke in September, emissions testing has come under greater scrutiny, and none more so than in Europe, where critics have long been highlighting the weaknesses of the testing system. Ironically, changes to the emissions testing process were already under review but the story has pushed it up the agenda.

Here, Jason Barnes and David Crawford look at the latest developments in the sector. A notable aspect of machine vision is the flexibility it offers in terms of how and how much data is passed around a network. With smart cameras, processing capabilities at the front end mean that only that which is valid need be communicated back to a central processor of any descripti
