Advantages of Gas Detectors for Industry Applications
When it comes to gas detector, people in the industry will not be unfamiliar with this instrument. Gas detector is a kind of instrument tool that can detect the concentration of gas leakage, through its built-in important components - gas sensor, the gas in the workplace for the collection, and through the physical or chemical non-electrical signals into electrical signals, and then through the external circuitry of the above electrical signals rectification, filtering, etc. processing, after processing the signal can control the corresponding module to achieve the specific functions of the gas detector. The processed signal can control the corresponding module to achieve the specific functions of the gas detector.
The gas detector can detect combustible gases, toxic and hazardous gases, including but not limited to hydrogen sulphide, carbon monoxide, oxygen, sulphur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone and combustible gases.
Because there are so many types of detectable gases, gas detectors are divided in a variety of ways. For example, the gas detector can be divided into combustible gas (including methane) detector, toxic and hazardous gas detector, oxygen detector according to the classification of detection object.
Gas detector according to the detection principle classification, detection of combustible gases detector catalytic combustion type, semiconductor type, thermal conductivity and infrared absorption type, etc.; detection of toxic and hazardous gases detector electrochemical type, semiconductor type, etc.; detection of oxygen detector electrochemical type, etc..
And according to the use of classification, can be divided into portable and fixed.
Classified according to the use of the place, can be for the conventional type and explosion-proof type.
Gas detectors can not only detect a number of different types of gases, but also, the role of the gas detector is very strong.
According to the difference in the field of use of gas detectors, gas detectors are mainly used in two major levels, namely, industrial gas detection instrumentation and civilian gas detection instrumentation.
Industrial gas detectors have two categories: portable and fixed, while the fixed type can also be used with a controller to form a complete gas detection system. Industrial gas detectors are mainly used in petroleum, chemical, metallurgy, coal mine, liquefied gas and other enterprises;
Civilian gas detector has independent plug-in type and socket type with line, mainly used in public places and family with gas detection alarm, and simple household type gas detection alarm, is mostly used for gas leakage detection in the family.
