Introduction to sulfur dioxide sensors
The sulfur dioxide sensor for mining can be used in various underground situations to continuously monitor, display, and alarm the sulfur dioxide content in the air flow of various underground places. At the same time, it outputs signals to provide monitoring data for the monitoring substation.
Working principle of sulfur dioxide sensor
The oxidation reaction occurs at a certain control potential on the working electrode of sulfur dioxide. When the point control is positive enough and the catalytic activity of the electrode is high enough, the oxidation reaction proceeds quickly. The total speed of the process is determined by the diffusion step of sulfur dioxide, and the generated signal current is proportional to the concentration of sulfur dioxide.
