SECOND SIGHT TC Infrared Gas Cloud Imaging Camera • 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. Sight is a registered trademark of Bertin Technologies, S. A., France 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. Applications • Chemical Plants • Compressor Stations • LNG/LPG Storage, Processing, and Transport • Gas Turbines • Offshore Platforms • Refineries
