Gas Detection-Refrigerant Leak Detection

The typical CO2 Gas Sensor for refrigerant leak detection should be ranged 0-3% CO2, with warning set points at % (8 Hour TWA allowable exposure) and alarm set points at % (10,000ppm) CO2. With the above warning and alarm set-points, the recommended actions would be to investigate a potential Carbon Dioxide leak at %, and shut down valves to the evaporator and evacuate the …

Gas Leakage Detection Using Thermal Imaging Technique

eyes, but can be read by thermal images, so the thermal camera is used to detect the gas leakage. As we all already know, gas is the matters that are freely moving. Gas can exist in the liquid state or solid because it can be compressed within a high pressure. During the transportation operation, maybe some problem will happen, such as, pipeline leakage, the corrosion of the pipeline or ...

📸Using thermal cameras to visualize gas leaks - Drone ...

If a thermal camera reads a scene without a gas leak, objects in the angle of view will radiate and reflect infra-red radiation that react through both the lens and the filter on the detector. The filter only lets some wavelengths of radiation enter the detector, from which the camera generates an uncompensated image of the radiation intensity of the radiation – this corresponds to the ...
