Product Overview
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. They offer a compact size, wide operating temperature and pressure ranges, and a choice of mounting threads, making them ideal for applications such as tank level control, leak detection, pump control, and sump level switching. The high power, industrial supply voltage, and direct load drive design provide significant advantages.
