General Description
The Pathfinder Scanner utilizes the latest
microprocessor technology to ensure precise reliable detection.
Whereas old style HMD's purely detect the hot product
pre-set thresholds, the pathfinder scanner 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 will not raise its trip level.
While static analog HMD's utilize single diode
detection and rotary scanners incorporate rotating mirrors, the
pathfinder scanner utilizes a digitally scanned InGaAs Diode Array.
This new technology removes the maintenance associated with rotary
scanners yet provides the high reliability and 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. To assist in alignment, product path is
duplicated by an LED Bar Display. Which is also used to indicate
adjustments to precise values.
