Dust Water Protection Digimatic Indicator

  • Our unique ABS sensor restores the last origin position automatically when the indicator is
    turned on.
  • The chance of overspeed errors has been eliminated thanks to the ABS sensor.
  • Rated to IP66: can be used satisfactorily even in adverse environments where the indicator is subject to splashing by cutting fluid or coolant.
  • Slim body design (body width: only 35mm) is advantageous in multipoint measurement situations where space is restricted. The LCD readout can also be rotated 180° to allow reading from the most convenient direction.
  • Succeeded in digitalization of the Back Plunger type widely used for dial indicators for ID-B.  A 5mm-stroke plunger with a higher degree of accuracy has been implemented by adopting a direct reading scale for plunger displacement.
  • Built-in tolerance judgment function provides OK, +NG, or –NG judgment of measurement with respect to the preset upper and lower limit values, indicating the status of a measurement with the appropriate symbol. The symbols can be displayed much larger.
  • Equipped with a data output port that enables incorporation into measurement networking and statistical process control systems.
  • There is a choice of convenient Interface Input Tools which enable the conversion of measurement data to keyboard signals and directly input them to cells in off-the-shelf spreadsheet software such as Excel.

Two of the wires inside the cable are separated for zero setting without touching the SET switch on the main body.
Use these cables in combination with commercially available switches. Zero setting is performed by briefly connecting these two wires together (less than a second), and ABS preset & recall by connecting for a second or more.
• Contact points for Mitutoyo’s dial indicators (Refer to pages F-51 to F-54 for details.)
