SafEye 300 Duct Open Path Detectors were specially designed and are widely used to monitor and alarm against ingress of hazardous gas concentrations into air intakes of turbine engines and HVAC air ducts. Formation and migration of gas clouds and their possible penetration into safe places, control rooms, turbine engines, etc. is a substantial risk that needs to be addressed.

Users, designers and safety and operational engineers are increasingly required to provide for adequate and fast detection and alarm to protect these hazards.

For duct applications, over a small path across an air inlet, the system is designed to respond with a very high sensitivity, full scale of 1 LEL.m for 2-6.6 ft. (0.6-2 m) wide inlet and full scale of 2.5 LEL.m for 6.6-23 ft. (2-7 m) wide inlet.

The SafEye 300 Duct system, due to its special optics design, provides for a misalignment tolerance of 2° in all directions and is protected against false gas reading and alarms which are caused by partial obscuration and blocking, misalignment, vibration, flexing or tilts.

Each SafEye unit is factory calibrated in a temperature cycle run at the entire operating temperature range. The temperature compensating mechanism allows correct operation in changing and extreme temperatures while maintaining the system’s accuracy. Its internal microprocessor will automatically compensate for low signals with its internal Automatic Gain Control (AGC).

The SafEye 300 Duct system can be factory calibrated to gas mixtures that are associated with offshore production and processing and onshore installations.

High Sensitivity
  • Alarm up to 0.5 LEL.m
  • 5 times more sensitive than the normal Open
  • Path equipment
Fast Response
  • Fast response time of 2 seconds.
  • 5 to 10 times faster than the commonly used Open Path detector and 20-50 times faster than the Point Detector.
  • Low Maintenance

    High reliability, simple installation, alignment and maintenance, equipment not subject to poisoning.

    Proven Technology

    Used in air ducts on FPSO’s and offshore rigs for British Petroleum (BP), Shell and ABB Lummus for turbines, air intakes, etc.

    Harsh Environment

    Specially designed to perform under extreme conditions such as high-speed airflows, high temperatures (up to 158 ̊F (70 ̊C)), humidity and corrosive gases, where point detectors may not be effective.

    Standard Interface Options

    Standard 4-20 mA outputs or RS-485 output to allow networking (up to 64 detectors) to a central monitoring/PC system.

    This feature also enables easy maintenance, local and remote diagnostic tools.

    Accessories

    The following optional accessories designed for the SafEye system are available.

    Duct Mounting

    The duct mount interfaces between the detector and the duct surface.

    The duct mount enables the detector's alignment up to 3 ̊ in all directions (P/N 794716).

    Commissioning / Alignment Kit for standard and duct type units is required for commissioning and future maintenance checks. Only one kit is required per site.

    The kit includes an Alignment Telescope P/N 794110, a Magnetic Mode Selector P/N 790285 and a Function Check Filter P/N 794220-1÷5 for system testing along with socket keys for access to units (P/N 792247).

    Typical Applications

    Offshore Oil & Gas Rigs and FPSOs; Onshore Oil & Gas Terminals; Storage Farms and Filling Stations; Petrochemical and Chemical Industries; Power Utilities and Turbines areas; Automotive, Painting, Printing, Pharmaceutical Industries and many more...
