ELECTRO-OPTIC TYPE
ELS-1150
Compact Electro Optic Level Switch available in
Nickel-Plated Steel or Stainless Steel
The enhanced ELS-1150 series is the highest performing electro optic level switch from
Gems Sensors. The ELS-1150 features a microprocessor board design to provide a wide
range of capabilities including sinking and 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 (172.37 bar). Built with solid state reliability, the
sensor is available at an affordable price in Nickel-Plated Carbon Steel or Stainless Steel.
The compact size of the sensor makes them ideal candidates for monitoring the small,
pressurized vessels found in HVAC, refrigeration and hydraulic applications in Oil and Gas.
The sensors are most commonly used for low, high and intermediate level detection in a
variety of media.
The stainless steel version (ELS-1150SS) is excellent for application requiring corrosion
resistance and is ideal for acids, solvents and dielectric water applications. An explosion
proof version, ELS-1150XP, is excellent for applications in Oil & Gas that require small,
accurate level sensing of constant media (ie. hydraulic fluid or coolant).
