🛠Gas detector is a device that detects the presence of gases in an area, often as part of a safety system.
🛠A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave.
🛠This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
🛠Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.
🛠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.
🛠They may be used in firefighting.
🛠Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors.
🛠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.
🛠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.
🛠Common sensors include combustible gas sensors, photoionization detectors, infrared point sensors, ultrasonic sensors, electrochemical gas sensors, and metal–oxide–semiconductor (MOS) sensors.
🛠More recently, infrared imaging sensors have come into use.
