Gems Sensors & Controls ELS-1150 electro-optic level switch

Gems Sensors & Controls has introduced the ELS-1150 solid state electro-optic level switch for high-temperature and high-pressure applications.

The 35 mm long switch has been enhanced with 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 172 bar (2500 psi).

The series is available in versions with wide voltage ranges and temperature ranges up to 125°C (ELS-1150XP) and is available in nickel-plated carbon steel or stainless steel.

The compact size of the sensors makes them suitable for monitoring the small, pressurised vessels found in HVAC, refrigeration and hydraulic applications and are most commonly used for low, high and intermediate level detection. The stainless steel version (ELS-1150SS) is suitable for applications requiring corrosion resistance, such as with acids, solvents and dielectric water, as well as medical and petroleum applications.
