A gas detector or sensor is a device that detects the presence of gases in an area and is often used as part of a safety system. A gas detector can alarm operators in the area where the leak is occurring, allowing them to evacuate. Gas detectors are important due to the toxic nature of many gases.
Gas detectors can detect combustible, flammable and toxic gases and oxygen depletion. Gas detectors are widely used in various industries and can be found on oil rigs to monitor oil production and emerging technologies such as photovoltaics. Gas leak detection is the process of identifying hazardous gas leaks by sensors. Additionally, visual identification is made by using a thermal camera. The gas sensors usually employ an audible alarm to alert people after detecting dangerous gas. Exposure to toxic gases also occurs in painting, fumigation, fuel filling, construction, excavation of contaminated soils, landfill operations and entering confined spaces. Common sensors include combustible gas sensors, infrared point sensors, photovoltaic sensors, electrochemical gas sensors, ultrasonic sensors and metal-oxide-semiconductor sensors.
Infrared imaging sensors have recently been used in a variety of applications. Industrial plants, fumigation facilities, refineries, pharmaceutical factories, paper mills, steelmaking plants, metal refineries, shipyards, hazmat operations, waste-water treatment facilities, vehicles, indoor air quality testing, and homes use infrared sensors.
