The cost-effective Micro Resistive Displacement Transducer is ideal for measuring small linear position changes. With a spring return control rod, installation can be completed very quickly.


  • Very cost-effective
  • Small physical size, spring return
  • Wide input (excitation) range
  • Infinite resolution (depends on user’s A/D system)
  • Stable DC output
  • Fast mounting


  • Diagnostic load testing bridges
  • Testing river control structures
  • Crack opening
  • Expansion joint movement
  • Laboratory testing
