Where as normal HMDs purely detect hot product above pre–set thresholds, the PATHFINDER operates by microprocessor comparison of the background and hot product signal. Neither static hot scale or steam in the field of view causes false triggering. Furthermore, lens contamination does not raise trip level.

Whilst static analogue HMDs utilise single diode detection and Rotary Scanners incorporate a motor, the PATHFINDER Scanner utilises a Germanium Diode Array. This new technology removes the maintenance associated with Rotary Scanners provides the high accuracy associated with Scanners.

Microprocessor technology provides exceptionally fast and accurate detection of Rod or Strip leading/trailing edge where wide variations of IR signal are present. Response times are digitally adjusted by locking timers. Furthermore, to assist in alignment, product path is duplicated by an LED Bar Display.
