69 International Road Dynamics (IRD) will present its new Saw III portable axle scale and VectorSense sensor technology at the ITS World Congress Melbourne.

The Saw III scale is OIML 76 certified and suitable for enforcement weighing of commercial trucks. IRD’s Saw I and II models were portable wheel load weighers with a strong reputation for durability. New features introduced with this version of the Saw scale are an improved zero-setting function, a single NiMH battery pack with battery status display, an improved charge cycle, IP 65 rated interface connectors, and Bluetooth compatibility.

The Saw III scale is also available in a dynamic weighing version that can be used for screening vehicles at slow speed using weigh-in­motion (WIM). New software is available for both static and dynamic scales.

The VectorSense tyre sensor suite is an in-road sensor technology that provides vehicle position and individual tyre footprint data for use in traffic data collection programs, commercial vehicle operations (CVO), and toll road operations.

VectorSense sensors’ ability to distinguish vehicle types by tyre characteristics makes them particularly well suited to multi-modal traffic data collection. These sensors provide data on all types of vehicles, enabling engineers and planners to collect and analyse traffic data to optimise infrastructure investments, such as bike lanes, bike paths, and bike share locations.

    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

    IRD, Inc's Terry Bergan discusses future applications of weigh in motion technology. The application in recent years of Weigh In Motion (WIM) at tollgates has been driven by recognition of the fact that there is economic value, which can be levied, attached to Heavy Goods Vehicles (HGVs) which haul laden (and are therefore heavy) rather than empty. As wear and damage to road surfaces increases exponentially with weight, the targeting of HGVs in particular makes sense from both the economic and maintenance p
