Senscient Enhanced Laser Diode Spectroscopy Open Path Detector
Senscient ELDS™ Series 1000 CH4 Methane OPGD Detector
Applications:
Offshore Platforms, FPSO's, Onshore Petrochemical facilities and Refineries.
Theory of Operation:
Using a separate transmitter and receiver configuration, Senscient ELDS™ Series 1000 CH4 Methane OPGD systems can detect and measure methane over distances between 5 and 200 m. The ELDS technique measures the Harmonic Fingerprint introduced onto the transmitter's laser beam(s) by absorption by any target gas in the monitored path.
Senscient ELDS™ Series 1000 XD Cross-Duct & HVAC OPGD Detector
Senscient ELDS™ Series 1000 XD Cross-Duct & HVAC Features / Benefits:
Applications:
HVAC ducts, turbine inlets, turbine acoustic enclosures.
Theory of Operation:
Using a separate transmitter and receiver configuration, Senscient ELDS™ 1000 Series OPGD systems can detect and measure methane in ducts between 0.5m and 5m wide. The ELDS technique measures the Harmonic Fingerprint introduced onto the transmitter's laser beam(s) by absorption by any target gas in the unit's path.
Senscient ELDS™ Series 2000 H2S Hydrogen Sulfide OPGD Detector
Senscient ELDS™ Series 2000 H2S Features / Benefits:
Applications:
Offshore Platforms, FPSO’s, Onshore Petrochemical facilities and Refineries.
Theory of Operation:
Using a separate transmitter and receiver configuration, Senscient ELDS™ Series 2000 H2S Hydrogen Sulfide OPGD systems can detect and measure hydrogen sulfide over distances between 5 and 40 m. The ELDS technique measures the Harmonic Fingerprint introduced onto the transmitter’s laser beam(s) by absorption by any target gas in the monitored path.
Senscient ELDS™ 2000 Series 2000 H2S+CH4 Simultaneous Methane & Hydrogen Sulfide OPGD Detector
Senscient ELDS™ Series 2000 H2S+CH4 Features / Benefits:
Applications:
Offshore Platforms, FPSO's, Onshore Petrochemical facilities and Refineries.
Theory of Operation:
Using a separate transmitter and receiver configuration, Senscient ELDS™ 2000 Series OPGD systems can detect and measure methane and hydrogen sulfide over distances between 5 and 40 m. The ELDS technique measures the Harmonic Fingerprint introduced onto the transmitter's laser beam(s) by absorption by any target gas in the monitored path.
In the vast majority of instances, hydrogen sulfide is found as a component of the solution gas or natural gas present at the facility, intimately mixed with predominantly methane. When solution gas or natural gas containing hydrogen sulfide leaks, its components do not separate regardless of the density of the individual gases. It remains intimately mixed and the hydrogen sulfide follows the same leak path as the rest of the gas.
