Factory Automation Systems
Spring Loaded LVIT Linear Position Sensor
Long Lasting, Contactless, Inductive Sensors
The LRS-18 series of LVIT (Linear Variable Inductance Transducer) spring loaded position sensors by Alliance
Sensors Group are contactless devices designed for dimension or position measuring applications in factory
automation and in various industrial and commercial applications such as automotive testing, mil/aero test
stands, robotic arms, and packaging equipment, where the sensing element cannot be attached to the object
being measured. LRS-18s are offered in full scale ranges from 12.5 to 100 mm (0.5 to 4.0 inches) with excellent
resolution and high stroke-to-body-length ratios. The maximum tip force on the item being measured is 1 pound.
LRS-18 sensors have a 19 mm (0.75 inch) diameter aluminum or stainless steel body with an M18 x 1 thread
and come with two hex jam nuts for easy installation in place of an 18 mm analog prox sensor. These sensors
use a 0.25 inch diameter probe equipped with an AGD No. 9 contact tip, and are offered with either an axial
cable or a connector. Operating from a variety of DC voltages, the sensors are available with a choice of four
analog outputs and they all include ASG’s proprietary SenSet
™
field calibration feature.
