The enhanced Gems ELS-1150 series is the highest performing electro-optic level switch. At just 35 mm (1.38″) long, the ELS-1150 has been upgraded with a microprocessor board design to provide a wide 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 172 bar (2500 psi). The Gems ELS-1150 series is available in FM and EP versions with wide voltage ranges (ELS-1150XP) for Oil & Gas. 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 sensors makes them ideal for monitoring the small yet 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 excellent for applications requiring corrosion resistance and is ideal for acids, solvents and dielectric water applications. Higher temperature versions are available up to 125°C (257°F).
