    Applications of NO2 Gas Detector

    Tips: Portable gas detector working principle

    The gas detector can detect a variety of gases, and is widely used in petrochemical, coal, metallurgy, chemical, municipal gas, environmental monitoring and other places for on-site detection. It can meet the measurement needs of special occasions; it can detect gas concentration or leak detection in tunnels, pipelines, tanks, confined spaces, etc.

    The type of gas can be distinguished by measuring the absorption spectrum, the concentration of the gas can be determined by measuring the absorption intensity. The infrared detector has a wide range of use, which can not only analyze the gas composition, but also the solution composition, and has high sensitivity, rapid response, and continuous online instructions, and it can also form an adjustment system. The detection part of the infrared gas detector commonly used in industry is composed of two parallel optical systems with the same structure.

    One is the measurement room and the other is the reference room. The two chambers open and close the light path at the same time or alternately at a certain cycle through the light cutting board. After the gas to be measured is introduced into the measurement chamber, the light with the unique wavelength of the gas to be measured is absorbed, so that the luminous flux entering the infrared receiving gas chamber through the optical path of the measurement chamber is reduced. The higher the gas concentration, the less the luminous flux entering the infrared receiving gas chamber; and the luminous flux passing through the reference chamber is constant, and the luminous flux entering the infrared receiving gas chamber is also constant. Therefore, the higher the concentration of the gas to be measured, the greater the difference in luminous flux passing through the measurement chamber and the reference chamber. This difference in luminous flux is projected to the infrared receiving air chamber with the amplitude of a certain period of vibration.

    The receiving gas chamber is divided into two halves with a few micrometers thick metal film. The chamber is sealed with a large concentration of measured component gas, which can absorb all the incoming infrared light within the absorption wavelength range, so that the pulsating luminous flux becomes the periodic change of temperature can be converted into a pressure change according to the gas equation, and then detected by a capacitive sensor. After amplifying, the concentration of the gas to be measured can be indicated. In addition to capacitive sensors, quantum infrared sensors that directly detect infrared can also be used, and infrared interference filters are used for wavelength selection and tunable lasers are used as light sources to form a new all-solid-state infrared gas detector. This kind of detector only uses a light source, a measuring chamber, and an infrared sensor to complete the gas concentration measurement. In addition, if filter discs equipped with multiple different wavelengths are used, the concentrations of various gases in multi-component gases can be measured separately at the same time.
