Gas leak detection methods became a concern after the effects of harmful gases on human health were discovered. ![]() All of these sensors are used for a wide range of applications and can be found in industrial plants, refineries, pharmaceutical manufacturing, fumigation facilities, paper pulp mills, aircraft and shipbuilding facilities, hazmat operations, waste-water treatment facilities, vehicles, indoor air quality testing and homes. More recently, infrared imaging sensors have come into use. Common sensors include combustible gas sensors, photoionization detectors, infrared point sensors, ultrasonic sensors, electrochemical gas sensors, and metal–oxide–semiconductor (MOS) sensors. Exposure to toxic gases can also occur in operations such as painting, fumigation, fuel filling, construction, excavation of contaminated soils, landfill operations, entering confined spaces, etc. Additionally a visual identification can be done using a thermal camera These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors. This type of device is used widely in industry and can be found in locations, such as on oil rigs, to monitor manufacturing processes and emerging technologies such as photovoltaic. ![]() ![]() Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. Device to detect the presence or absence of gasesĪ gas detector is a device that detects the presence of gases in an area, often as part of a safety system.
