Liquid Level Sensor For Flammable Atmospheres

Posted on December 4, 2013

Gems Sensors & Controls has released a new electro-optic liquid level sensor designed for use in flammable and explosive atmospheres.

At 2-in. in length, the ELS-1150XP Series sensor designed for monitoring the small, pressurized vessels found in oil, gas and petrochem environments, such as storage tanks, chemical injection equipment, compression tanks, hydraulic oil vessels, glycol tanks, and other well head automation equipment, the company said.

The sensors have no moving parts and are available in nickel-plated carbon steel or stainless steel. The fused glass prism is designed to eliminate leaks and is capable of operation in temperatures ranging from -40°F to 257°F and in pressures up to 5000 psi. 

The explosion-proof ELS-1150XP series is manufactured for use in environment classified as Class I, Div. I, Groups A, B, C, and D; Class II/III, Groups E, F, and G.  These are areas containing flammable bases or vapors in quantities sufficient to produce explosive or ignitable mixtures. The ELS 1150XP is approved for use with virtually all hydrocarbon based liquids and gases, as well as with combustible atmospheres containing dusts of coal, coke, flour, or starches of other grains, the company said.
