Tips: How does PTFE protect submersible level sensors?

PTFE provides a highly corrosion-resistant protective layer for a submersible level sensor, isolating the cable and internal components from corrosive liquids. Its excellent chemical resistance allows it to withstand seawater, salts, weak acids, weak alkalis, and other aggressive media, while its low surface energy helps resist liquid and contaminant adhesion. This combination improves cable durability, insulation stability, and long-term reliability, making PTFE protection particularly suitable for level sensors used in harsh submerged environments.
