Products

IRD’s iSINC® Electronics form the core of IRD's Weigh-In-Motion (WIM) systems. Out of the box, iSINC® performs a broad range of Intelligent Transportation System (ITS) functions, from data collection and web-based traffic monitoring, to weigh-station automation. A “lite” version of the iSINC® provides a compact, rugged, and energy-efficient system that is a popular choice for modernizing data collection systems. The iSINC® is a suitable controller for IRD’s WIM scales and sensors and also those produced by other vendors. A wide variety of peripherals, including cameras and message signs, also interface with the iSINC®.
IRD’s software is used in systems for traffic data analysis and reporting (VI2M™, iAnalyze®), in toll systems (iToll®), and for operating weigh stations and virtual weigh stations.
IRD’s High Speed Weigh-In-Motion (HSWIM) scales are suitable for WIM applications including weigh station sorting systems, traffic monitoring, bridge protection, WIM@Toll® applications and data collection. IRD’s SLC Load Cell scales have established a benchmark for reliability, and thousands of IRD-PAT Bending Plate Scales are incorporated in ITS systems worldwide.
IRD’s portable WIM systems include the TRS WIM for data collection and the DAW 300 and SAW III scales for enforcement weighing.
In addition to WIM, IRD supplies a variety of complementary technologies such as off-scale sensors and toll treadles. IRD recently introduced TACs, a tire anomaly and classification system that uses IRD’s VectorSense™ tire sensor suite to screen for commercial vehicles that are unsafe due to missing or underinflated tires.
