Senscient ELDS™ Open Path Gas Detectors (OPGD)

ELDS™ is a patented, new open path gas detection (OPGD) technology from Senscient. The innovative Enhanced Laser Diode Spectroscopy (ELDS) detection technology featured in our ELDS Series of open path gas detectors truly fulfills the promise of fit-and-forget open path gas detection...

• Reliable detection of both toxic & flammable gases.
• Industry’s first false-alarm free Open Path Gas Detector. ELDS detection is molecular species specific, eliminating false alarms from common atmospheric or non-hazardous gases that plague traditional OPGD (or any NDIR or LDS technology) systems.
• FIRST and ONLY laser open path combustible gas detector to meet current industry Safety and Performance Standards.
• FIRST and ONLY gas detector with SimuGas™, an electronic, remote functionality check.
• 3 orders of magnitude greater sensitivity for combustible gases versus conventional NDIR-based detectors.
• Up to 60% reduction in gas detection project CapEx and OpEx, with true Fit-&-Forget functionality.
• Backed by a network of industry-leading gas detection solutions providers.

Senscient ELDS OPGD Series 2000 H2S+CH4 Detector

• Reliable, open path detection of both methane and hydrogen sulfide in a single unit.
• Faster response than any other hydrogen sulfide detection technology.
• No need to replace or re-calibrate sensors.
• No false alarms from any other gases including diesel fumes or oil mist.
• True ease-of-installation, with vibration and misalignment tolerant optics.
• SimuGas™ feature provides ability to accomplish on-demand, remote functionality testing right from the control room or PLC!
• 316L Stainless steel construction designed to provide maximum corrosion resistance for installation in sea and land-based Hazardous Area facilities.

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+CH4 OPGD systems can detect and measure methane and hydrogen sulfide over distances between 5 and 60 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.
