Intercomp expands OIML certifications for sensors

First published in Intertraffic Innovation News - May 7, 2020

Intercomp’s weigh in motion (WIM) strip sensors have achieved OIML R134 Class 5E certification at low- to medium-speeds. This adds an industry first to the company’s high-speed WIM applications with OIML R134 Class 10F certification for two, three or four-row configurations of the technology. To achieve this type certification, 2.5 per cent GVW accuracy at low to medium speeds, and 5.0 per cent at high speeds is required.

OIML certification recognises the ability of strain gauge strip sensor technology to collect WIM data in free-flow applications reliably. Ranging from low-speed weight and monitoring applications to automated electronic toll collection (ETC) and direct weight enforcement, the certified sensors can be used up to mainline highway speeds.

Intercomp’s WIM strip sensors are installed and grouted in place into 3-inch (75mm) channels cut into the pavement, lowering installation requirements and traffic disruption to a single day with minimal civil works. The patented strain gauge technology is optimised for WIM applications, actively compensating for a wider range of temperature variables to provide responsive, stable and repeatable weighing in a variety of operating environments and weather conditions. The Intercomp sensors feature connectivity to communicate weight data either via a CPU or integrate directly to a host of other controllers and software for incorporation into ITS systems with cameras and other sensors.
