The LZ-33 Series of LVIT (Linear Variable Inductance Transducer) position sensors are contactless devices designed for frictionless measurement in factory automation or assembly machinery applications where space is a premium, as well as for external mounting on hydraulic cylinders to sense rod position.
This sensor is offered in nominal full scale ranges from 6 to 36 inches (150 to 900 mm) with an excellent stroke-to-length ratio. The sensor's overall length is only 3 inches (76 mm) longer than the linear range of the unit. The sensor has a 1.315 inch (33.4 mm) outside diameter aluminum or optional stainless steel body with a 1 or 3 m radial cable for I/O connections. The 0.670 inch (17 mm) diameter through-bore of an LZ-33 provides clearance for its 0.645 inch (16.4 mm) diameter 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.
