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.
