Overview / Design Principle: 

By integrating a 1 amp relay into the stem, we've made the ULS-11 our most compact ultrasonic unit. Yet, as unobtrusive as it is, the ULS-11 still delivers ultra-reliable solid-state performance in lengths up to 99 inches. Tip gap probe configuration places sensing point at 1/4 inch from probe tip for closer tank bottom sensing. Electronics are completely epoxy sealed for years of maintenance free service. 

Gems ULS Series of ultrasonic switches are designed for a broad spectrum of viscous light liquids; including some of the most challenging liquids you may deal with: acids, freon, paints lacquers, etc. They're built to withstand high temperatures and pressures with welded stainless steel sensor probes that have no seals to leak and no moving parts to wear out. ULS Series switches are unaffected by variation in temperature, pressure, density or type of liquid. In most cases, electronics are housed in cast aluminum, NEMA 4/NEMA 7 explosion proof and watertight enclosures.
