Sources of gas sensor performance requirements

Gas sensors are used to detect the ambient atmosphere ( volume concentration ) and thus are often exposed to the environment, the use of various components , which are sometimes very harsh working conditions ( plus high temperature, humidity , etc. ) , sensitive materials will deteriorate over time , deteriorate the material surface adsorbate persist, its performance will decline . Thus requiring Shaft Position Sensor able to work under harsh environmental conditions . Then the performance of the conditions need to be met : 1, can selectively detect a single gas , while the other gases coexist is not responding or not sensitive ; 2 , the measured gas has a high sensitivity to detect the volume concentration ranges specified the gas ; 3, the signal fast response, good reproducibility ; 4 , long-term job stability ; 5 , the manufacturing cost and the use of lower priced universal ; six easy maintenance.So far fully meet the above requirements of Crankshaft Positioning Sensor is also difficult to achieve, but people are trying to take advantage of micro- computer technology as well as a combination of several gas sensors and pre- processing means perfect combination of gas sensor performance.
