• Excellent stroke-to-body ratio
• Full Scale ranges from 0.1 to 30 inches (2.5 to 750 mm)
• Environmental rating of IP67 (Dust tight, Short term water immersion)
• Through-bore design eliminates mechanical overstroking
• Proprietary SenSetfield adjustable range scaling
• DC in / DC out operation with built-in electronics
MADE IN THE USA
UL approved for use in Hazardous Locations
The LZ-19 Series of LVIT (Linear Variable Inductance Transducer) position sensors are contactless devices designed for use in hazardous locations such as oil and gas exploration, power generation valve feedback and chemical/food processing where UL approval is required.
The LVIT is offered in nominal full scale ranges from 0.1 to 30 inches (2.5 to 750 mm) with an excellent stroke-to-length ratio. The sensor has a 19 mm (3/4 inch) outside diameter stainless steel with a 1 m axial cable for I/O connections. The 6 mm (0.236 inch) diameter through-bore of an LZ-19 provides clearance for its 5.2 mm (0.200 inch) diameter, PVDF-sheathed moving rod, which is made of the same material as its housing. This through-bore feature also means that the sensor is not subject to damage from typical mechanical overstroking.
