Gas Sensors Used in Industrial, Civil, Environmental Monitoring
The gas sensor is a certain gas volume fraction of conversion into a corresponding electrical signal converter. There are a wide range of gas sensors. The application is quite extensive. Gas sensors have a wide range of applications in civil, industrial, environmental detection.
The gas sensor applications in civil mainly to detect a the civilian gas leak of natural gas, liquefied petroleum gas and city gas in the kitchen , detect microwave food cooking gas to automatic control of microwave cooking food; housing, building, meeting rooms and places of public entertainment to adhere to the carbon dioxide, smoke, ozone and unpleasant gas, automatic operation and control air purifier or fans; rise buildings used to detect fire signs and alarm. Currently, civilian areas is the main application areas of semiconductor metal oxide gas sensors. This is mainly because of the semiconductor metal oxide gas sensors are inexpensive, the performance can also meet the requirements of the home alarm.
Gas sensors in industrial applications are mainly used in the stone in the chemical industry to detect carbon dioxide, nitrogen oxides, sulfur oxides, ammonia, hydrogen sulfide, and chlorine and other harmful gases; semiconductor and micro- electronics industry to detect organic solvent and highly toxic gas phosphine ; hydrogen power industry detection power transformer oil metamorphic process; perishable food industrial inspection meat food freshness; detection of oxygen in the exhaust gases of cars and furnaces industrial control of combustion, to achieve the twin goals of energy conservation and environmental protection ; Highway Traffic detect the driver's breath in the ethanol gas concentration to prevent drunk driving and reduce traffic accidents.
Environmental detection of course, can not be separated from the gas sensor, such as the application sensor detects nitrogen oxides, sulfur oxides, hydrogen chloride, which causes acid rain gases; detect carbon dioxide, methane, nitrous oxide, ozone, Freon and other greenhouse gases; detection of ozone, ozone-destroying gases such as Freon; detect ammonia, hydrogen sulfide and gas unpleasant gas.
In summary, the gas sensors based on their different functions in the civil, industrial, environmental testing has a significant role. After further transformation of the sensor, the scope of its application will be more extensive. We will see in more situations gas sensor applications.
