Mahr Federal Introduces µMaxµm II Digital Indicators

Upgrades include multiplier factor for ratio measurements and resolution to 10 µin.

Published: Thursday, March 10, 2011 - 12:40

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

“µMaxµm indicators have been standard equipment for quality control operations for nearly a generation,” says Paul Mailloux, manager of precision gauges for Mahr Federal. “Now, based on new transducer technology with increased 10 µin. resolution, µMaxµm II indicators approach the accuracy of higher-end amplifier systems. These are by far the most versatile and complete digital indicators ever.”

Versatility of the µMaxµm II indicators is enhanced in a number of ways. Resolution is selectable in increments from 0.001 in. (0.02 mm) down to 0.00001 in. (0.0002 mm) 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 gauge fixtures using lever-type nondirect contacts.

Data output with indicator serial-number identification is an excellent gauge 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 gauges need to be pulled for recalibration.

Other useful µMaxµm II features include normal or 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 that conserves power and helps ensure long life from readily available commercial batteries.

The new µMaxµm II line of digital indicators is available in two models: the µMaxµm II and the µMaxµm II XL, which provides longer measuring ranges.

Weighing as little as 6 oz, all µMaxµm units are lightweight and ruggedly built to withstand hard use. The gasketed case, crystal, and stem assemblies resist fluid contamination.
