Features

Benefits

• Wide field of view and long detection
range

• Large coverage area per device

• Requires no gas calibration in the field

• Reduced maintenance

• Able to deselect specific areas within
the field of view that are not of interest
or could contain known sources of
false alarm

• Allows camera to be focused on an
area without being affected by a
false alarm source

• Simultaneous detection of up to
four gases

• Flexibility to detect broad range
of gases

• Able to identify location of gas leaks
to a section within the field of view

• Allows operators to address gas
leaks at the source

• Quantification and visualization of gases

• Real time gas concentration display

Description
Second Sight ® 1 is a remote gas detection system designed
to provide an additional layer of safety in the detection of
combustible and toxic gases. Second Sight uses an
uncooled microbolometer array to identify and visualize
gas leaks in real time. The infrared (IR) remote gas
detector is suited for simultaneously detecting several
combustible and toxic gases at up to 2,000 m. With a
standard 30° field of view, Second Sight provides wide,
continuous monitoring of critical areas.
In addition to large coverage areas per device, Second
Sight is designed for ease of use. A human machine
interface (HMI) allows operators to see target gases as
they are detected by the IR camera. Levels of gas
concentrations overlaid on a video image provide a
unique picture of gas dispersal that allows personnel not
only to address the source of a leak, but also to respond
more effectively to an alarm based on the direction of
the gas cloud. Further, the HMI also allows users to
mask zones within the field of view that are not of
interest or could be sources of false alarm.

Second Sight requires no gas calibration in the field. An
automatic optical check performed every 30 minutes
assesses optical path integrity (window cleanliness),
optical alignment, and the position of the focal plane array.
The result is a system that requires little maintenance and
is immune to major false alarm sources.
The video recorder function in Second Sight allows the
operator to play back an alarm event or record the current
detection. Stored files enable facility management and
safety personnel to view video images and concentration
profiles of events as they unfold over time. Users can
retrieve and examine alarm events in detail by using the
standard commands of a video recorder. The enhanced
event logging reduces the time and complexity of managing
safety records and informs management of potential
improvements at the target site.
