GEMS Sensors & Controls, which supplies innovative sensor and miniature solenoid valve designs to OEMs, has introduced its ELS-1150XP Series electro-optic liquid level sensors designed and approved for areas where flammable and explosive atmospheres exist. At just two-inches in length, these compact sensors are ideal candidates for monitoring the small, pressurised vessels found in oil, gas and petrochemical environments. They accurately monitor level in applications such as: storage tanks, chemical injection equipment, compression tanks, hydraulic oil vessels, glycol tanks, and other well head automation equipment.

These rugged level sensors have no moving parts and are available in nickel-plated carbon steel or stainless steel. The strong fused glass prism eliminates leak potential and is capable of operation in temperatures ranging from -40°F to +257°F (-40°C to +125°C) and in pressures up to 5000 psi.

“With nothing to clog, these optic sensors give a unique way of monitoring high and low level conditions in a variety of applications,” says Ryan Lisiak, oil and gas market manager at Gems Sensor

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. These are areas containing flammable bases or vapours 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.
