The Zone III magnetic signature changes as staff and equipment move around and Zone IV doors open, making it difficult for other FMDs to identify a threat. The IRadimed FMD continuously adapts to its ever changing environment by employing advanced, highly sensitive sensors allowing true magnetic threats to be detected. IRadimed’s patent pending Trusense technology predicts an approaching ferrous hazard by uniquely combining Time of Flight sensing of a threat’s speed, trajectory and Zone IV door status, with IRadimed’s expertise in Dynamic Signal Processing. This clever technology reduces false alarms, all while simultaneously circumventing background magnetic field noise, resulting in the True Sense of a True Hazard.
