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
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
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.
- Alarm up to 0.5 LEL.m
- 5 times more sensitive than the normal Open
High reliability, simple installation, alignment and
maintenance, equipment not subject to poisoning.
Used in air ducts on FPSO’s and offshore rigs for
British Petroleum (BP), Shell and ABB Lummus for
turbines, air intakes, etc.
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
Standard Interface Options
Standard 4-20 mA outputs or RS-485 output to
allow networking (up to 64 detectors) to a central
This feature also enables easy maintenance, local
and remote diagnostic tools.
The following optional accessories designed for the
SafEye system are available.
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).
