Fiber-optic sensing systems from Micron Optics approved for use in explosive environments
Atlanta, GA--Micron Optics, a provider of equipment for fiber-optic sensing and laser imaging, announced that its Fiber Bragg Grating (FBG)-based optical sensing systems are certified for use in explosive environments according to the International Electrotechnical Commission's Certification to Standards relating to Equipment for use in Explosive Atmospheres (IECEX). Micron Optics now offers optical sensing instruments, modules, and sensors for continuous long-term use in the presence of explosive atmospheres. The DNV 10 ATEX 82688 certification was conferred by the professional testing and qualification firm of Det Norske Veritas AS.
With this international certification, global customers working with explosive environments can be assured that Micron Optics' optical sensing systems meet the IEC's standards for intrinsically safe products. Intrinsically safe products receive their classification because both their power use and power storage properties are below the levels required to set off an explosion in a hazardous area.
Compared with electronic sensors, fiber-optic strain and temperature sensors provide higher accuracy and range of measurement and an order of magnitude higher resistance to mechanical fatigue. These sensors are completely passive and immune to electromagnetic interference, lightning, and corrosion. Dozens of FBG sensors can be included along a single fiber.
Micron Optics has accepted its first order for an application requiring the IECEX certification. The customer will be deploying Micron Optics optical sensing systems in liquefied natural gas (LNG) tankers. Petrochemical plants, waste water operations, the mining industry, nuclear facilities, and aircraft fuel tanks are also ideal applications for optical monitoring systems.
