SafEye Quasar 900 Open Path Combustible Hydrocarbon Gas Detector

Quick Overview

The New SafEye Quasar 900 is an open path detection system which provides continuous monitoring for combustible hydrocarbon gases. It employs “spectral ﬁngerprint” analysis of the atmosphere between a transmitter and detector unit to determine the levels of the Hydrocarbon gas present using the Differential Optical Absorption Spectroscopy (DOAS) technique. The Xenon Flash Infrared transmitter and receiver units can be separated over a line of sight from 7m up to 200m. The Quasar 900 transmitter and receiver are both housed in a rugged, stainless steel, ATEX and IECEx approved enclosure. The Quasar 900 includes heated windows to eliminate condensation and icing, HART capability for digital communication and is designed to meet SIL2 per IEC61508 and FM performance approved per FM6325 and tested per EN60079-29-4.

Details

The SafEye Quasar 900 Series is the very latest open path IR technology and detects a wide range of hydrocarbon gases – including alkanes (methane to hexane) and ethylene. Spectrex invented the xenon flash lamp design that revolutionized the open-path gas detection market, which, until then, was plagued by false alarms due to the drawbacks of the previous designs. Now, Open path detectors complement the use of individual point detectors, take executive action and offer many significant benefits.

Features

Applications

Offshore platforms & FPSOs
Petrochemical plants
Chemical processing plants
Gas filling and distribution terminals
Gas transport and pipelines
Large storage areas & buildings
Perimeter monitoring

The Quasars 900’s high power xenon lamp will compensate for changing weather conditions, including rain, fog, mist, snow and makes it immune to influences from solar radiation, arcwelding, stack flares or vibration from machinery. The optical lenses are thermostacically heated to prevent the formation of ice and build up of snow on the optics even under severe weather conditions. It also eliminates build up of condensation on the lenses. Quasar is rated for operation over a very wide temperature range from -67°F to + 149ºF (-55ºC to + 65ºC)

The SafEye detection system monitors the level of gas present between the transmitter and receiver units and provides a measurement out in LEL.meters instead of in %LEL as used with point type gas detectors. Both examples below show gas clouds with readings in LEL.meter.
