Product Overview
The SafEye Quasar 950/960 UV Open-Path Gas Detector employs an advanced
Xenon UV Source and integrated electronics package, both of which are encased
in improved stainless steel housings, which provide high quality and performance,
fast response, and line-of-sight gas monitoring. The complete SafEye system is
backed by a 3-year warranty.
The Quasar 950/960 is manufactured only from stainless steel, with a heated
optical window to improve performance in ice, snow, and condensation
conditions. The programmable functions are available through a RS-485 or HART
port used with host software supplied by SPECTREX, and a standard PC or IS
handheld unit.
The Quasar Source and Detector unit enclosures are ATEX and IECEx approved.
They are Exd flameproof with an integral segregated rear, and an Exe terminal
compartment, which avoids exposure of the sensors and electronics to the
surrounding environment. The detector also has a plug interface for connection to
a handheld PC or HART unit, which meets intrinsically safe standards.
This manual provides a full description of the detector and its features. It includes
instructions on the installation, operation, and maintenance of the detector.
•
To use the WinHost software to change the required functions, and for a
description of its maintenance, please refer to
Manual TM899050
for
instructions.
•
To use the HART Protocol to change the required functions, and for a
description of its maintenance, please refer to

. To set
functions, the HART can be connected on the 0
–
20mA line or through the IS
port.
The SafEye Quasar 950/960 detects and monitors toxic gases, such as ammonia,
H
2
S, and aromatics, ppm.m concentrations in the air. SafEye has a response
detection time of no more than 10 seconds.
The SafEye system uses an open path beam of flashlight pulses that provides a
long line of sight coverage equivalent to a large number of point detectors along
the path. The transmitted beam covers a UV spectrum from 200
–
300nm. The
SafEye Quasar 950/960 constantly monitors for the gas through the collimated
beam, over an optical path of up to 200ft/60m.
Warning:
The source and detector are not field-repairable due to the meticulous
alignment and calibration of the sensors and the respective circuits.
Do not attempt to modify or repair the internal circuits or change their
settings, as this will impair the system's performance and void the
SPECTREX Product warranty.
