Oxygen measurement in nitrocellulose gelatinization processes presents unique challenges: flammable atmospheres requiring explosion-proof certification, organic solvent vapors that can interfere with sensors, viscous media affecting sensor response, and strict safety interlock requirements.
This guide covers critical selection criteria including sensor technology comparison (polarographic vs. optical vs. zirconia), material compatibility, response time requirements, installation best practices for hazardous areas, and maintenance considerations specific to this demanding application.
