Warum fallen meine SO2-Sensoren frühzeitig aus?

Warum sind SO2-Sensoren empfindlich gegenüber Umweltfaktoren? Einfach ausgedrückt, macht die chemische Zusammensetzung der SO2-Sensoren sie anfällig für die Umgebungseinflüsse. In den SO2-Sensoren befindet sich ein wasserbasierter Elektrolyt. Dieser Elektrolyt kann bei niedriger Luftfeuchtigkeit leicht sein Wasser verlieren, was die Elektronenmobilität verringert und seine …

Warum fallen meine SO2-Sensoren frühzeitig aus?

In den SO2-Sensoren befindet sich ein wasserbasierter Elektrolyt. Dieser Elektrolyt kann bei niedriger Luftfeuchtigkeit leicht sein Wasser verlieren, was die Elektronenmobilität verringert und seine Fähigkeit beeinträchtigt, am chemischen Reaktionszyklus im Inneren des elektrochemischen Sensors teilzunehmen. Auch sein Gefrierpunkt variiert mit der umgebungsbedingten Konzentrationsänderung ...

Why are My SO2 Sensors Failing Early?

· Why do SO2 Sensors Recover? While the electrolyte in SO2 sensors can easily lose its water under low humidity conditions, it can also absorb moisture from the air. This increases the ion mobility and causes the sensor sensitivity to recover. You’ll find that the sensor will then pass calibration. The results of increasing and decreasing humidity can be seen in a long-term review of an SO2 ...

Gassensor – Wikipedia

Problematik chemischer Sensoren. Das Gebiet der chemischen Sensoren ist relativ jung. Während Sensoren zum Messen physikalischer Größen wie beispielsweise Temperatur, Druck und Beschleunigung wasser- und luftdicht verschlossen sind, steht ein chemischer Sensor wie der Gassensor in direkter Wechselwirkung mit seiner Umgebung. Dadurch ist er auch wesentlich …
