Each gas has its own absorption spectrum and presents typical absorption peaks in infra-red bands II (3 to 5 µm MWIR) and bands III (8 to 14 µm LWIR). Second Sight operates in band III, in order to use the particular peaks to enables the identification of a vast majority of gas. The Second Sight measurement principle uses the scene background as an infra-red source, and image processing algorithms to highlight the presence of a gas cloud in line of sight.
A gas cloud tracking system, based on Infrared technology, which provides an innovative solution for industrial safety.
Second Sight TC is an infrared gas imaging camera which can detect the presence of gas cloud at a distance of up to several hundred metres.
This instrument makes visible emissions that may otherwise be invisible to the naked eye. In case of toxic or explosive gas leak, the gas cloud is automatically detected, depicted as an overlay on the infrared image and monitored in real time.
A network of multiple cameras can enable the tracking of a gas cloud in an industrial area. This innovative solution for industrial safety provides key information directly to a central control room with a real time visual representation of the gas cloud and its motion. It can also be deployed temporarily to enhance the efficiency of leak detection, as well as protecting critical infrastructure or workers.
- Optical gas imaging with automatic detection.
- 24/7 surveillance.
- Multiple gas detection capability.
- Suitable for network and remote operation.
The Second Sight TC infrared gas imaging camera is suitable for both punctual short-term monitoring and long-term monitoring, depending on the task and purpose:
- Automatic detection.
- Real time gas cloud visualisation.
- Source point of the leak.
- Movement of the cloud in the plant.
- Network and 24/7 surveillance.
In case of alarm, the presence of gas cloud is displayed as an overlay on the infrared image. The identification and estimated path length concentration are given in top left corner and the gas is underlined in red in the gas list.
The latest version of Second Sight is becoming a universal gas detector with its new detection algorithm Gas X, an unknown gas detection capability that enables the detection of any gas cloud modifying the infrared signature in band III of the observed scene, even if the gas is not listed into the system’s database.
