ELECTRO-OPTIC TYPE
ELS-1150XP
FM-Approved Explosion-Proof
The explosion-proof ELS-1150XP series is designed for use in areas containing flammable
bases or vapors in quantities sufficient to produce explosive or ignitable mixtures. It
is FM-Approved for use with virtually all hydrocarbon based liquids, as well as with
combustible atmospheres containing dusts of coal, coke, flour, starch of other grain.
These solid-state level sensors are available in nickel-plated carbon steel or stainless
steel. The strong fused glass prism eliminates leak potential and is capable of handling
high temperature and pressure applications up to 5000 psi. The compact size of the sensor
makes them ideal candidates for monitoring the small, pressurized vessels found in oil, gas
and petrochem environments.
