Overview / Design Principle:
The ULS-10 Series features a Tip Gap probe design for closer tank bottom access. The miniaturized, encapsulated electronic control unit may be supplied for remote mounting, or directly mounted on sensor in an explosion-proof, NEMA enclosure. FM-Approved, explosion-proof enclosures are also available.
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 water tight enclosures.
