LVDT and displacement sensors provide frictionless, non-wearing measurement with theoretically infinite resolution, making them the preferred choice for precision gauging and closed-loop position control. The following applications are the most common scenarios covered in SEGMENsensor technical documentation.
Dimensional Gauging and Quality Control: Spring-loaded SLT series LVDT pen sensors measure part dimensions in gauge fixtures on production lines. The consistent spring contact force ensures repeatable measurements across thousands of parts without calibration drift, with 0–10 V output feeding directly into data acquisition systems.
Machine Tool Slide and Spindle Position: Linear displacement sensors with IP67 sealing monitor tool position, workpiece clamp position, and spindle extension in CNC machining centres, grinding machines, and EDM equipment. Absolute position output eliminates referencing runs after power-off.
Structural Deformation and Vibration Monitoring: High-resolution LVDT sensors measure structural displacement, bearing clearance, and vibration amplitude in turbines, compressors, and civil engineering structures. The non-contact sensing principle eliminates probe wear under continuous dynamic loading.
