The Open Path Gas Detectors include the two series of ds900 and ds700 which we will explain in this post.<\/p>\n

Open Path Gas Detector ds 900 Series Laser Detector:<\/strong><\/p>\n

The SafEye Quasar 900 series features the latest open path IR technology that detects a wide range of hydrocarbon gases including alkanes (methane to hexane) and ethylene.
\nThe model can travel up to 660 feet (200 meters) in length, and you can use Quasar 900 models to protect high-risk installation.
\nReliability and performance are key, and trust this product with SIL2 verification and performance testing, and having FM and EN standards.<\/p>\n

Why Open Path Gas Detectors?<\/span><\/strong><\/h3>\n

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.
\nNow, Open path detectors complement the use of individual point detectors, take executive action and offer many significant benefits including:
\n\u2022 Wider area coverage
\n\u2022 Most likely method to pick up any leak
\n\u2022 Very high speed of response
\n\u2022 No unrevealed failure modes
\n\u2022 Beam block warning
\n\u2022 Detector location is less critical
\n\u2022 Size of gas hazard indicated
\n<\/span><\/h3>\n

Applications include:<\/strong><\/h3>\n

\u2022 Offshore platforms & FPSOs
\n\u2022 Petrochemical plants
\n\u2022 Chemical processing plants
\n\u2022 Gas filling and distribution terminals
\n\u2022 Gas transport and pipelines
\n\u2022 Large storage areas & buildings
\n\u2022 Perimeter monitoring<\/span><\/p>\n

QUASAR OFFERS OPTIONS FOR YOUR INSTALLATION:<\/span><\/strong>
\n\u2022 0-20mA analog output with HART capability
\n\u2022 RS485 Modbus, where up to 256 detectors can be linked<\/span><\/p>\n

Worldwide Approvals<\/strong><\/h3>\n

\u2022 Hazardous area (Zone 1) FM\/FMC, ATEX, IECEx, GOST R Inmetro
\n\u2022 Performance (3rd party):
\nFM 6325 approved by FM
\nEN60079-29-4 tested by FM
\n\u2022 Reliability:
\nSIL2 (TUV)<\/span><\/p>\n

HART<\/strong><\/h4>\n

HART capabilities within the Quasar 900 can provide digital communications between the field and the safe area.
\nThis can provide real time information on the status of an individual detector as well as configuration and historical data of each device, without the need for extra cable cores.
\nA key feature of HART is that digital signals are transmitted on the same two wires as the 0-20mA current signal.
\nUseful and useable information available via HART includes:
\n\u2022 Display set-up
\n\u2022 Reconfigure set-up \u2013 such as gas
\ncalibration, heater control, address
\n\u2022 Display detector status and definition
\n\u2022 Perform detector diagnostics
\n\u2022 Troubleshooting

Open-path Gas Detection Concepts<\/strong><\/h3>\n

Not all gas clouds are hazardous – only if a flammable gas cloud or plume is wide enough to allow flame acceleration to speeds greater than 100 m\/sec does it become a significant threat.<\/span><\/p>\n

\u2022Just as an athlete performing the long jump needs a run-up distance, so too a flame front needs distance to reach the velocities which cause the damaging effects of over pressure, pressure pulse and windage.<\/span><\/p>\n

\u2022The generally accepted quantity of gas that creates the potential to cause consequential damage if ignited is a cloud of the size 5 m diameter a stoichiometric concentration (about200% LEL).<\/span><\/p>\n

\u2022 To provide a safety margin, this concentration is halved to 100% LEL. Thus an open path beam traversing this cloud would indicate 5 LEL.m.<\/span><\/p>\n

\u2022Location of the SafEye 700S Open-Path Gas Detector is less important than with point type detectors as it provides a warning alarm from a diluted gas cloud and does not need to be close to the leakage source.<\/span><\/p>\n

\u2022 Point type detectors measure gas at their location in terms of % LEL, whereas open-path gas detectors measure the amount of gas anywhere along the length of the path, in terms of the integral of concentration and length (LEL x meters).<\/span><\/p>\n
