1.1 Product Overview
The SafEye 200 Series IR Open-Path Gas Detector employs an advanced
Flash Source and integrated electronics package to provide high quality and
performance, fast response, line of sight gas monitoring.
SafEye detects ambient combustible gases at LEL.m concentrations over a path
length of up to 459-ft. (140 m), even in harsh environments where dust, fog, rain,
snow or vibration can cause a high reduction of signal. Due to its unique
combination of triple optics and dual-spectrum reference sensor, the SafEye can
maintain operation in up to 90% signal obscuration and ±1 degree of
misalignment.
SafEye has a fast response detection time of no more than 5 seconds. This
feature enables an adequate time to take appropriate safety measures.
The SafEye Source and Detector unit enclosures are ATEX certified EExd
flameproof or EExde with additional separate EExe terminal box connected to the
unit.
