Open path gas detection
From WikiCover
On August 16, 2007, Senscient announced SenseLine ELDS OPGD (open path gas detection), a gas detection system employing its patented Enhanced Laser Diode Spectroscopy (ELDS) technology. The company's ELDS gas detection technology features three orders of magnitude better sensitivity for flammable gases and - for the first time - false alarm-free, low ppm level toxic gas detection in an economical open path configuration.
SenseLine ELDS OPGD is targeted to meet new safety requirements in the Oil, Gas and Petroleum Processing industry for improved plant and personnel protection from dangerous gas leaks. The Senscient SenseLine ELDS OPGD is slated to complete field tests this year, with commercial products available through its distributors in February 2008.
Open path IR detection technology requires fewer units to establish a detection zone compared to existing point-type gas detectors. However, existing tungsten or pulsed xenon-based open path systems are only capable of detecting flammable gases. In addition, the older systems are only able to detect leaking gas at levels already high enough to cause considerable damage if ignited.
The Senscient SenseLine ELDS OPGD transmitters and receivers may be spaced from five meters up to 200 meters apart (and further depending upon the target gas and levels). When low ppm-meter levels of a hazardous gas pass through any part of the laser line, the system can report the presence of the gas leak early enough to allow remedial action by the user.
