Linear position sensors monitor structural integrity of LNG storage tanks

NewTek hazardous location position sensors monitor the structural integrity of LNG tanks where natural gas is cooled to cryogenic temperatures at liquefication facilities, then stored as a liquid until pumped into LNG tanker ships for export.

Approved for use in Class 1, Zone 0, and Zone 2 locations, the hazardous location certifications of the company’s NT-HL-750 series of LVDT are said to be preferred in this application.

Even though the space between the inner and outer tank containers is normally filled with nitrogen, the company says, a leak in the inner tank can result in gas seeping into the space between the tanks where the sensors operate.

Intertek-approved and holding an ETL certification for use in hazardous locations throughout North America, the sensors also operate safely and accurately in hazardous and explosive environments with the presence of flammable or ignitable gases and liquids such as those found in refining and petrochemical plants and pipelines.
