XS-D Schaevitz™ Long Stroke-to-body Length LVDT

LVDT XS-D

The XS-D Series of LVDTs are specifically designed for measuring relatively large displacements where installation space is limited. The XS–D Series have a substantially greater displacement range than standard LVDTs but without the accompanying increase in body length and weight. Using special coil winding techniques, the XS-D permits linear range measurements of up to 80% of the housing length.

Compact, shock and vibration tolerant, and featuring infinite resolution and repeatability, the XS-D Series are the perfect choice for servo mechanisms, linear potentiometer replacement, or wherever precise displacement measurements are required in space restrictive applications. All models are supplied with a calibration certificate, and are available with either an imperial or metric threaded core.

Features

  • Superior stroke-to-length ratio
  • Stroke ranges from ±25.4 mm bis 254 mm
  • Smooth transfer function
  • Stainless steel housing
  • Calibration certificate supplied with all models

Applications

  • Servo mechanisms
  • Hydraulic actuators
  • Linear potentiometer replacement
  • Space restrictive installations
  • Weight sensitive applications
