Safety Latest Industrial Flame Detectors from Spectrex
SharpEye 40/40 Series Flame Detectors offer un-matched perfor- mance and reliability- including patented, IR3 (Triple IR) Multi- Spectrum detectors that enable detection of small fires at distances up to 65m, with enhanced immunity to false alarms. 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.
The latest SharpEye 40/40 Series flame detectors include the model 40/40I using the well-proven IR3 detector, offering the highest immunity to false alarms combined with a massive 65m (215ft) detection distance for hydrocarbon fires with an enlarged cone of vision – 100º horizontal and 95º vertical.

Another major feature is the improved response to gas flames
(methane, LNG, LPG, etc.) where small gas flames can be detected at distances of up to 30m (100ft). An important addition to the series is the model 40/40M Multi IR detector, which can simultaneously detect ‘invisible’ hydrogen flames at 30m (100ft) and hydrocarbon fires at 65m (215ft).
The 40/40 series comprises many detection techniques to suit every situation including triple IR (IR3), Multi IR, combined UV/IR, single IR or UV. Thus, Spectrex can offer unbiased advice on which detector is the correct solution to your detection needs.
The compact and lightweight design (only 2.5kg in stainless steel) offers low-power consumption with a heated lens for continued availability in difficult environments - as well as the reassurance of 3rd party FM / EN54-10 / DNV performance approvals and IEC 61508 - SIL2 (TUV) certification to assure reliability. All detectors are, of course, Ex approved to ATEX / IECEx / FM/ CSA/ GOST R / GOST K standards for Zone 1/21 hazardous area location.
The 40/40 Series detectors incorporate an integral automatic self- test which checks the devices every 15 mins to ensure correct operation. The 40/40 Series offers many interface options to ensure that the detec-tors are compatible with all control and fire detection systems – outputs include 0-20mA, dry relay contacts, RS-485 ModBus and HART.
The certified operating temperature range has also been extended. The detec-tors will now operate reliably in temperatures from -55ºC to + 75ºC (with an option for +85ºC) allowing their use anywhere in the world.
SafEye Open-Path Gas Detection for Combustible Gas Hazards
Fig 3: Ed - Safeye 700
Spectrex’s SafEye ‘Line-of-Sight’ IR Hydrocarbon Gas Detectors feature unprecedented reliability and exceptional detection capability for flammable hydrocarbon gases/vapours in a wide range of hazardous conditions and ambient environments.
SafEye Open Path Hydrocarbon Gas Detectors, Series 700 and 200, monitor for combustible hydro-carbon gases 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 1 meter (or 25%LEL over 4 meters, etc).
The ’flash’ type radiation source ensures immunity to any false alarms and the unit functions effectively even in extreme environments, such as fog, rain, smog etc. Heated optics are also available to ensure continued detection in extreme weather conditions. If the ‘open-path’ is ever completely blocked due to environmental or human intervention, a warning signal will be generated to allow corrective action or investigation.

The 40/40 Series detectors are programmable, allowing the user to alter factory default settings. Sensitivity levels, response time, alarm delay, heated lens operation, etc. are all able to be modified where required, either pre-delivery or after installation. Various accessories are provided including a Flame Simulator to allow full ‘end- to-end’ proof testing in the Ex hazardous area.
Alignment is a simple one-man operation using a telescope – no electronic hand held device needed or connecting cables between source and detector units. The wide alignment tolerance ensures that SafEye maintain reliable detection and availability in extreme vibration conditions.
SafEye detectors are fully Exd approved to ATEX and UL standards with a full range of interfaces including mA analogue, RS485 and HART. A SIL2 version is also available.

Monitoring for Combustible Gas Ingress into Turbine and Air Intake Ducts
As well as long distance detection, the SafEye open-path technique is also employed in a duct mount arrangement to allow rapid and reliable hydrocarbon gas / vapour detection in applications such as turbine intakes and air intake ducts. This arrangement is very fast responding in 1 second or even less, does not require a sampling system, and can be located in ducts from 0.6m up to 8.0m wide

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 in tough environments where operations are high risk and safety is paramount.
