The Optomax Industrial Glass Series liquid level switches are designed to detect the presence or absence of oil or water-based liquids. Featuring a corrosion-resistant 316L stainless steel housing with a hardened glass tip, these switches are suitable for harsh industrial environments. Their compact size, wide operating temperature and pressure ranges, and choice of mounting threads make them versatile for various applications including tank level control, leak detection, pump control, and sump level switching. They offer high power capabilities and direct load drive design.
