Integrates well-proven and superior Xenon Flash technology which has an excellent operational record in many installations ranging from the deserts of Africa and Asia and the very hot and humid Middle East, to the wet and cold North Sea and the dry and cold regions of Alaska.

Fast Response
Powerful light source and advanced detector gives high sensitivity and rapid response to the presence of gas.

One-Person Commissioning
Installation, alignment, and commissioning easily completed by one person.

Wide Range of Detectable Gases
Reliable detection of gas presence including a wide range of gaseous hydrocarbons, such as Alkanes, Alkenes (C1-C8), Alcohols, LNG, LPG, and Ethylene.

Robust Design
SIL2 Rated. Specifically engineered to perform in harsh installations such as high-velocity airflows, humidity, corrosive gases, and up to 90% beam blockage. Stainless steel 316L, IP66/67, Zone 1 ready enclosure.

Cost Effective
A single system can monitor line-of-sight up to 460 feet (140 m). The low cost of ownership, low installation costs, and minimal maintenance requirements further contribute to cost savings.

Large Misalignment Tolerance
Provides wide angle of view to withstand vibration, mechanical shock, and displacement.

Standard Interface Options
Standard 4-20 mA output with “Maintenance call” (3 mA). Optional RS-485 Modbus output to allow networking to a central monitoring / PC system facilitating local and remote diagnostic tools.

The Spectrex SafEye 700 Optical Open Path (Line of Sight) Gas Detection System employs “spectral fingerprint” analysis of the atmosphere using the Differential Optical Absorption Spectroscopy (DOAS)technique in a unique (patented) method.

SafEye 700 consists of an advanced Xenon Flash infrared transmitter (source) and infrared detector(receiver), separated over a line of sight from 13 ft. (4 m) up to 460 ft. (140 m) to detect and quantify flammable gas presence, even when challenged by extremely harsh environmental conditions where dust, fog, rain, snow or vibration can cause a high reduction of signal.

The SafEye 700 analyzes atmospheric absorption at three selected spectral bands, two in a region where the target gas absorbs and one where it does not absorb. The ratio between these absorption lines can provide accurate information of the gas concentration along an optical path.

The reference sensor detects beam blockage, compensates for changing humidity and detects failed light source or dirty optics.

SafEye’s source and detector units are both housed in low profile, rugged, stainless steel, ATEX approved enclosures. The main enclosure is approved EExd flameproof with an integral, segregated, EExe increased safety terminal section. The hand-held communication unit can be connected in-situ via the intrinsically safe approved (EExia) data port on the detector. The combined ATEX approval is therefore Ex II 2(1)GD, EExde ia [ia] IIC T5 (55?C).

SafEye 700 includes heated optics on the transmitter (source) and receiver (detector) to address icing, condensation and snow.

Accessories include an Intrinsically Safe approved, Hand-Held Unit which is an all-in-one Diagnostic / Calibration / Interrogation plug-in unit that assists one-person installation and maintenance.
