Linear Variable Inductance Transducers (LVITs) from Alliance convert the linear displacement of an object into a proportional electrical signal output of 0-10V or 4-20mA. LVITs are contactless devices with no friction issues or moving parts that can wear out. LVITs exhibit outstanding repeatability and are used when higher accuracy is required. The Alliance LVIT SenSet™ process matches the end points of the sensor's analog output with the range of motion of a workpiece such as a hydraulic cylinder ram to optimize the position measuring resolution over the full range of motion. Configuration styles include spring loaded with ball tip, 19mm (0.75in) cylinder with rod eye mounting, and 27mm (1.05in) cylinder with rod eyes. Stroke lengths vary from 6.35mm (0.25in) to 457.2mm (18in). Linear inductance transducers (from $299.00) are CE, RoHS approved and have a 1-year warranty.
