Traffic Data Systems receives Swiss certification for WIM system

Traffic Data Systems’ WIM-DSP 32 low-speed and high-speed weigh-in-motion (WIM) system has been awarded an OIML-R134-1 certificate by the Swiss Federal Institute of Metrology, proving accuracy levels of ±5% (initial verification) and ±10% (in-service inspection) have been achieved. The Swiss institute’s supervised certification process required more than 500 test runs with different vehicles, speeds and loads.

The Swiss institute’s supervised certification process required more than 500 test runs with different vehicles, speeds and loads.


The WIM-DSP 32 is designed to operate with 657 Kistler’s line sensors and charge amplifiers, and features long-term sensor monitoring, an integrated colour graphics display and touch keys for easy configuration and function control. Potential uses range from data gathering to enforcement and tolling applications, including monitoring of track changes.

    On a WIM – a global view of weigh in motion
    Q-Free’s Andrew Lees looks at regional characteristics and technology trends in the global Weigh-In-Motion market. The principles of Weigh-In-Motion (WIM) are well established. Data derived from vehicles passing over in-ground sensors can be interpreted for vehicle classification (axle counts and spacing) and positive identification (especially when linked to image capture) applications as well as to derive individual axle and gross vehicle weight (GVW).
