UAV/Drone thermal imaging camera for gas detection – Workswell GIS-320

Under certain circumstances, infra-red cameras are highly suitable for detecting gas escapes 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 are hazardous to the environment and can threaten human health.

Some gases used in industry can significantly damage the environment and, therefore, it is essential to eliminate any uncontrolled leaks. Moreover, these leaks cost a lot.

“Traditional” methods for detecting gases require close contact of a probe with gas with the use of sensor technology. These methods are restricted due the time required and the risk of non-detection of some types of gases or too high selectivity (gas leaks to other places than where the sensor is located).

To detect gases, Workswell company offers a specially constructed infra-red camera, 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 (gas imaging system) thermal camera is the ideal solution for the unmanned air vehicles (drones/UAV systems) localization and detection of leaks of hazardous gases the option of standard communication with the environment through a CAN bus or PWM inputs. Of course, the thermal camera can record measured data, including GPS coordinates and the on-line HDMI transfer of the image to the side of the pilot.

The Workswell GIS 320 thermal camera is a highly precise thermal camera with a sensitive, cooled quantum detector with the resolution 320×240 and with a competitive temperature sensitivity of 15 mK, which also enables to detect gases of very small concentrations.

Detected gases:
Benzene, Ethanol, Ethylbenzene, Heptane, Hexane, Isoprene, Methanol, MEK, MIBK, Octane, Pentane, 1-Pentane, Toluene, Xylene, Butane, Ethane, Methane, Propane, Ethylene, Propylene plus hundreds of other hydrocarbons and Volatile Organic Compounds (VOC).
