Open Path Gas Detection
Sierra Monitor offers the Spectrex SafEye range of "line-of-sight" Optical Gas Detectors featuring a new generation of Open Path IR and UV detection systems. Open path spectroscopy offers unprecedented reliability in real-time monitoring of gaseous emissions over large areas, rendering it the accepted technology for industrial and environmental applications.
These systems provide exceptional detection capability of gas/vapor concentrations ranging from as low as Parts Per Million (PPM) levels to Lower Explosive Limit (LEL) levels in a wide range of hazardous conditions and ambient air monitoring.
SafEye System employs a unique flash light source coupled with optical detectors and mathematical algorithms to spectrally analyze an air path ranging from 2 ft. to 450 ft. (0.6m - 140m) with high detection sensitivity in both UV and IR spectral bands. The system is compatible with a wide range of control systems providing multiple outputs (dry contacts, 4-20mA, RS-485).
The open path line-of-sight gas detection system can monitor and transmit an alarm signal prior to occurrence of fire or an explosion, identify the chemical family concerned and activate preventative systems.
The SafEye gas detection system can serve as a process control component in the chemical and petrochemical industries, or as a safety system in commercial and industrial applications.
The Open Path Gas Detectors available from Sierra Monitor include:
Model 3560-2XX Flash Type
Open Path Detectors - used to monitor for combustible gases
at LEL levels over a line of sight of 460 feet. The 2XX series is built
for reliability and continued operation under all types of extreme environmental
conditions. .The unique flash source gives a very powerful radiation signal
vor a very short burst of time.
Model 3560-7XX Flash
Type XENON Open Path Gas Detectors - The 7XX has the same performance
advantages of the 2XX series, but adds valuable design features that are
important to certain applications. These additional features include: heated
lens, EExde housing (electronics are separated from wiring terminals), external
data port that can hook directly to PDA or handheld device as opposed to
wiring inside the 2XX series for RS-485 communications, and stainless steel
enclosure as standard.
Model 3560-4XX UV Open Path
Gas Detector - provides sensitive (PPM levels) monitoring of Hydrogen
Sulfide, Ammonia and Aromatic gases over an open path of up to 330 feet.
