Spectrex - SharpEye Flame Detectors and SafEye Open-Path Hydrocarbon Gas Detectors – for the Oil, Gas & Petrochemicals Industries

Spectrex is a world leader in development of unique optical flame and gas detection and suppression systems. For over 25 years, Spectrex products have met the highest customer requirements for fast response, reliable detectors where operation in tough environments and safety is paramount.

SharpEye Flame Detectors offer unmatched performance and reliability - including patented, IR3 (Triple IR) multi-spectrum detectors that enable detection of small fires at distances up to 60m, with enhanced immunity to false alarms.

SafEye 'Line-of-Sight' IR Hydrocarbon Gas Detectors feature unprecedented reliability and exceptional detection capability for flammable hydrocarbon gases/vapours over an open path up to 140m, in a wide range of hazardous conditions and ambient environments.

FLAME DETECTORS FOR ALL APPLICATIONS

New SharpEye 40/40 Series flame detectors are Ex approved, compact and low-power with a heated lens for use in difficult environments and RS-485 MODBUS, HART interface, 4-20mA and dry contacts outputs - as well as the reassurance of EN54-10 and SIL2 TUV approvals. Detection techniques are available to suit every situation including IR3, UV/IR, IR, UV and H2-IR3.

COMPACT, LOWER COST FLAME DETECTION

SharpEye 'Mini' Series Flame Detectors are used where accidental fires involve hydrocarbon-based fuels, hydrogen, metal and inorganic fires. These detectors are smaller, lower power, lower cost solutions for easy installation in small or congested areas and/or where hazardous area approvals are not essential (although some 'Mini' models are also available intrinsically safe approved).

For example, the model 20/20ML (UV/IR) provides rapid detection (50msec) at 30% less cost than an Ex approved version; it can 'see' a 1ft² (0.09m²) fire at up to 15m with a 100 degree field of view and has rugged st.st., IP65 design for use indoors/outdoors in high-risk situations. The model 20/20MI (IR3) can 'see' a 1ft² (0.09m²) fire at up to 40m and is commonly used in aircraft hangars where Ex approval is not required around the walls of the hangar.

NEW INVISIBLE HYDROGEN FLAME DETECTION SOLUTION

Sharpeye model 20/20SH specifically detects 'invisible' hydrogen flames. It has a wide range of applications in the emerging industrial and commercial use of hydrogen fuel.

PERFORMANCE AND RELIABILITY

SharpEye detectors are approved to performance standard FM3260-2000 and many to the more recent European EN54-10 (VdS). Another important factor is inherent reliability. Therefore, detectors certified by TUV to meet SIL2 requirements of IEC 61508 are available.

SAFEYE OPEN PATH GAS DETECTION TO IDENTIFY THE COMBUSTIBLE HAZARDS

SafEye Open Path Hydrocarbon Gas Detectors monitor for combustible hydrocarbon gases of over an open air 'path' of up to 460ft (140m) and can provide alarms prior to a fire or explosion event. The normal unit of measure for open-path detectors is the product of distance x concentration. Typical full scale is 0 – 5 LEL.meters i.e. 100%LEL over 1m (or 25%LEL over 4m etc).

SafEye functions effectively even in extreme environments, such as fog, rain, smog etc. If the 'open-path' is completely blocked due to environmental or human intervention, a warning signal is generated to allow corrective action.

DUCT MONITORING FOR GAS LEAKS

As well as long distance detection, the SafEye open-path technique is also employed in a duct mount arrangement to allow hydrocarbon gas/vapour detection in applications such as turbine intakes and air intake ducts. This arrangement is fast responding and does not require a sampling system.

RUGGED DESIGN FLAME AND GAS DETECTORS

All Spectrex flame and gas detectors are housed in rugged IP66 enclosures and most are hazardous area, Ex approved to various international standards including FM, ATEX, CSA, UL, GOST-R, and GOST-K. These highly specified detectors operate reliably in the harsh conditions of offshore drilling and production platforms, FPSO vessels, fuel loading and storage facilities, LNG and LPG plants and petrochemical plants throughout the world.
