Digital Indicators

March 01, 2011

Mahr Federal Inc. has introduced the next generation of its well-established μMaxμm line of digital indicators. In addition to the many existing features of indicators, the enhanced line offers a wide range of new features, including: Dynamic Max, Min, TIR; two point difference measurement; Multiplier Factor for ratio measurements; indicator serial number identification; resolution to 10 microinch selectable continuous output; and longer battery life.

Versatility of the new indicators is enhanced in a number of ways. Resolution is selectable in increments from 0.001 in/0.02mm down to 0.00001"/0.0002mm to accommodate differing application requirements. Two point difference measurement allows comparison of different readings or calculation of measured values. The addition of Multiple Factors for ratio measurements allows chordal-type measurements, useful for making ID/OD measurements using a V-plate, or for gage fixtures using lever-type non-direct contacts. Data output with indicator serial number identification is an excellent gage management feature. It can be used to improve ISO tracking, where a number of indicators are networked on a production line, or to identify which gages need to be pulled for recalibration.

Other useful features include: Normal/Reverse Sensing; a high resolution digital output with analog bar graph or Go/No-Go display; selectable MarConnect data output via USB, OPTO ES232C, or Digimatic; application of Unilateral Tolerances; and an auto power-down feature which conserves power and helps assure long life from readily available commercial batteries.
