ELDS™ OPGD Methane & Hydrogen Sulfide Detector
Product Announcement from Senscient Inc.
ELDS™ is a new open path gas detection (OPGD) system from Senscient Inc, based on innovative Enhanced Laser Diode Spectroscopy™ (ELDS) detection technology. ELDS™ OPGD systems provide many unique and attractive features designed to fulfill the promise of truly fit-and-forget open path gas detection.
Detects both toxic & flammable gases for up to 80% reduction in comprehensive gas detection project costs with true Fit-&-Forget functionality. FIRST and ONLY Toxic open path system to meet current industry Safety 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 OP systems. Perfect for detection of hazardous gases in critical applications. Backed by a network of industry-leading gas detection solutions providers. Proven technology, tested to meet oil and gas industry safety standards.
ELDS™ 2000 Series Features / Benefits:
- 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!
Offshore Platforms, FPSO's, Onshore Petrochemical facilities and Refineries.
Theory of Operation:
Using a separate transmitter and receiver configuration, 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.
