  • D-04 is an improved version of former D-01 and D-02 sensors.
  • D-04 is a universal displacement sensor with a
    customizable measuring range from 0-100mm.
  • The measuring range can be modified and extended
    upon the needs of the installation or measurement.
  • D-04 is featuring a novel construction with an optimized
    compensation design.
  • D-04 can be machined also from special alloys for
    universal and harsh environments applications (mines, subsea,


  • Dilatations
  • Settlement measurement
  • Crack monitoring
  • Strain and deformation measurement


  • Direct mountable (can be equipped with
    spherical polymer bearings)
  • Special design for harsh and demanding
    environments (mines, sub-sea applications)
  • Customizable cable lengths
