The enhanced ELS-1150 series is the highest performing electro-optic level switch from Gems Sensors.

At just 1.38" (35 mm) long, the ELS-1150 has been upgraded with a micro-processor board design to provide a range of capabilities, including sinking, sourcing and time delay outputs. The strong fused-glass prism eliminates leak potential and is capable of handling extreme temperature and pressure applications up to 2500 psi (172 bar).

The ELS-1150 series is available in FM and EP versions with a wide voltage range (ELS-1150XP) for the oil and gas industry.

Available in nickel-plated carbon steel or stainless steel. The compact size of the sensors makes them ideal for monitoring the small, pressurized vessels found in HVAC, refrigeration and hydraulic applications. The sensors are most commonly used for low, high and intermediate level detection.

The stainless-steel version (ELS-1150SS) is suited for applications requiring corrosion resistance and is ideal for acids, solvents and dielectric water applications. Higher temperature versions are available up to 257°F (125°C).

Key Features:

  • Operating Pressure – 0 to 2500 PSI
  • Operating Temperature – -40°F to +212°F (-40°C to +100°C)
  • Multiple applications including hydraulic and lubricating oil reservoirs; critical fluid level monitoring on machine tools, compressors, chillers and other industrial OEM equipment; corrosive liquids such as acids, solvents, and dielectric water applications; medical equipment; anesthesia, histology.
