Electronic gaging principles offer a variety of measurement solutions that benefit from a contact inspection approach. Common dimensional features include:

  • Diameters (inside / outside)
  • Runout
  • Concentricity
  • Squareness / Perpendicularity
  • Length / Height
  • True Position
  • Center to Center Distance
  • LVDTs

    These Linear Variable Differential Transformer (LVDT) gage probes operate with two, small electrical transformers which share a single core. When the core is centrally located between the two coils, the output is balanced or zeroed. When the core is physically displaced, the output of the two coils becomes unequal, with one coil increasing in output and the other decreasing. The measure of the core's movement is then recorded by these unequal outputs to represent true linear displacement or changes in size. These units are designed for used with all Edmunds Amplifiers.
