  Ultrasonic Level Switches

  Gems™ ULS Series of ultrasonic switches are designed for a broad spectrum of viscous to light liquids; including some of the most challenging liquids you may deal with: acids, freon, paints, lacquers, etc. Stainless steel units are 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. ULS-10 and ULS-100 electronics are housed in cast aluminum, NEMA 4/NEMA 7 explosion proof and water tight enclosures.

• Ultrasonic Switches Monitor the Toughest Applications
• Handles Pressures to 1000 psi (69 bar)
• Unaffected by Foam, Vapors, Particulate or Turbulences
• Lengths to 121 inches (3073 mm)
• Can be Side, Top or Bottom Mounted
• Easy to Install - Simple to Use

The ULS-1 Series has proven ultrasonic technology combined with micro-controller improved performance in aerated liquid for tight spaces. 

The ULS-1 Series Ultrasonic Level Switches are low cost, compact, level sensors with no moving parts, these small units are ideal for a variety of point level sensing applications especially where dependability and economy are a must.

These level switch units are suitable for high, low or intermediate level detection in practically any tank, large or small.  

Applications:

• Medical/Laboratory Equipment
• Pump Protection 
• Storage Tanks
• Compressors 
• Hydraulic Supply Lines
• Oil Film Detection
• Coolant Reservoirs
• Boiler Water Cutoff
• Hydraulic & Lube Reservoirs
• Chillers

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 (2515 mm). Tip gap probe configuration places sensing point at 1/4 inch (6 mm) from probe tip for closer tank bottom sensing. Electronics are completely epoxy sealed for years of maintenance free service.
