LVDT sensor for Hazardous Location

The NewTek NT-HL-750 series LVDT sensors are made for use in hazardous and explosive environments. Approved by Intertek Testing Laboratories and carrying the ETL mark as intrinsically safe for use in Class I, Zone 0 & Zone 2, the NT-HL-750 series LVDTs operate safely and accurately in hostile environments with the presence of flammable or ignitable gases and liquids such as those found in refining and petrochemical plants, pipelines, and oil and storage tanks.

Constructed using stainless steel and hermetically sealed to IP-67, the NT-HL series is rugged and robust with excellent protection against hostile environments. Electrical connections are made via lead wires exiting from a 1/2″ NPT fitting making for a easy installation into hard conduit.
