The ELS-1150XP Series electro-optic liquid level sensors are designed and approved for flammable and explosive atmospheres. These compact sensors (2" long) are suitable candidates for monitoring the small, pressurized vessels found in oil, gas and petrochemical environments. They can accurately observe storage tanks, chemical injection equipment, compression tanks, hydraulic oil vessels and glycol tanks. The ELS-1150XP Series, which has no moving parts and is available in nickel-plated carbon steel or stainless steel, is capable of operation in temperatures ranging from -40 to 257  °F (-40 to 125ºC) and in pressures up to 5,000 psi. Leak potential is eliminated by a strong fused-glass prism. The explosion-proof ELS-1150XP Series is manufactured for use in environments classified as Class I, Div. I, Groups A, B, C and D; and Class II/III, Groups E, F and G. It is also approved for use with almost all hydrocarbon-based liquids and gases and with combustible atmospheres containing dusts of coal, coke, flour or starches of other grains.
