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 gas Crankshaft Positioning 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 the gas Engine Water Temperature 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.
