GIS-320 RADIOMETRIC DRONE CAMERA FOR GAS DETECTION
FLIR is the exclusive global distributor of the Workswell GIS-320 Thermal by FLIR optical gas imaging payload for unmanned aerial systems, unmanned ground vehicles, and mobile platforms.
Under certain circumstances, infra-red cameras are highly suitable for detecting specific gases leakages and the presence of gas in the air. They can be also helpful during tests on improving environmental safety. A thermal camera can detect greenhouse gases in the air as well as gas leaks which may hazardous to the environment and can threaten human health.
ADVANCED METHOD FOR GAS DETECTION
Some gases used in industry can significantly damage the environment and may cost a lot of money if they go unnoticed. Therefore, it is essential to eliminate any uncontrolled leaks.
“Traditional” methods for detecting gases require direct contact between a probe and the gas with the use of sensor technology. These methods are restricted due the time required to get a reading from the sensor and the risk of non-detection due to the gas type or location of the leak (gases may leak to places other where the sensor is located).
FULLY SCANNED AREA
To detect gases, Workswell company offers a specially constructed thermal camera GIS-320 (gas imaging system), which is able to visualise gas on the principle of infra-red thermography. The thermal camera provides a full image of the scanned area and gas leaks are reflected in the image as changes in the intensity of detected radiation.
The Workswell GIS 320 thermal camera is a highly precise thermal camera with a sensitive, cooled MWIR quantum detector and a resolution 320×240 and with a precise temperature sensitivity of 10 mK, which also enables to detect gases in very small concentrations.
IDEAL SOLUTION FOR GAS LEAKS DETECTION
Workswell GIS 320 camera is the ideal solution to detect leaks of hazardous gasses via unmanned air vehicles (drones/UAV systems) as there are options to change image and camera setting such as, emissivity, gas intensity range, camera type, and more through standard RC transmitters connected to the CAN bus or PWM inputs. The thermal camera can also record measured data, including GPS coordinates and the wireless HDMI transfer of images to the pilot.
GAS DETECTION: NO CALIBRATION REQUIRED
The GIS-320 ability to detect gases is not influenced by any calibration process and will not degrade over time.
FLIR MWIR thermal core used in GIS-320 camera have been independently tested and deemed compliant with the EPA’s NSPS 40 CFR part 60, subpart OOOOa sensitivity standard for optical gas imaging equipment.
Testing was performed by the National Physical Laboratory (NPL), which confirmed the the core is capable of imaging a gas that is half methane/half propane at a concentration of 10,000 ppm at a flow rate of ?60g/hr from a quarter inch diameter orifice.
