1.1 Product Overview
The SafEye ‘Xenon’ IR Open-Path Gas Detector 700S employs an advanced
Xenon Flash Source and integrated electronics package, both housed in
improved, low-profile stainless steel housings to provide high quality and
performance, fast response, line of sight gas monitoring. This high quality is
backed by 3 years warranty for the complete SafEye system and 10 years
for the Xenon Flash source bulb.
SafEye ‘Xenon’ detects ambient combustible gases 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, dual-spectrum reference sensor, and heated
optics, the SafEye Xenon can maintain operation in up to 90% signal
obscuration and ±1 degree of misalignment.
SafEye Xenon is manufactured only in stainless steel with heated optical
window to improve performance in icing, snow, and condensation
conditions. The programmable functions are available through a RS-485 port
used with Host software supplied by Spectrex and a standard PC or an I.S
handheld unit.
The SafEye Source and Detector unit enclosures are ATEX and IECEx
certified Exd flameproof with an integral segregated rear, Exe terminal
compartment (which avoids exposure of the sensors and electronics to
surrounding environment), and an internal Exia intrinsically safe circuit
power for the heating of the window. The Detector also has a plug interface
for connection to handheld PC, which is intrinsically safe. Hence the
combined approval - Ex d e ia [ia Ga] IIC T5 Gb Ta.
