Gas detector

آشکارساز گازآGas detector or gas detector is a tool to detect the presence of a type of gas in a range and is usually part of a system to detect a type of gas harmful to human or animal health. Gas detectors for flammable, toxic gases, as well as oxygen and di Carbon monoxide, for example, is used in firefighting. Explaining the types and mechanisms of different types of gas detectors and sensors is beyond the scope of this discussion, but it is not bad to know that different methods of electrochemical, infrared, flame ionization, optical ionization, etc. are used to sense gas by the sensor. Others have different strengths and weaknesses. For example, the infrared method uses the fact thatMany gases absorb infrared rays at specific wavelengths or bands that are characteristic of the chemical structure of molecules in the gas. All hydrocarbon gases absorb infrared rays, but in varying degrees and with a certain percentage of absorption can Find out the type of gas.
