Caliper Attachment Wirelessly Transmits Data

Mitutoyo America has released the U-Wave Fit into its data management systems product line.

Mitutoyo America’s U-Wave Fit is a compact attachment for Mitutoyo calipers and micrometers that transmits measurements wirelessly to a PC using the Digimatic protocol. The elimination of long, cumbersome data cables is said to improve measurement efficiency and speed while maintaining precise accuracy. The user-friendly interface enables data to be uploaded into any software product that accepts keyboard input, the company says.

Named for what Mitutoyo calls a comfortable, ergonomic design, the U-Wave Fit can be installed on more than 1,600 different Mitutoyo calipers and micrometers. The unit’s design is said to enable the operator to handle and use the tool with comfort and confidence without sacrificing accuracy.

The product is available in models including IP67 and buzzer types for 4", 6", 8" and 12" IP67 calipers, standard calipers, and coolant-proof (IP65) micrometers. During standard operation, the U-Wave Fit has a wireless range of 20 m (60 ft.) and its 220-mAH battery lasts for over 400,000 transmissions. The high-resolution Digimatic2 communication format sends polarity and the unit of measure.

There’s a Micrometer for That

Match your micrometer choice to your specific machine shop needs.


  • Measuring Part Geometry On The Shop Floor

    Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.

  • Surface Texture From Ra to Rz

    The irregularity of a machined surface is the result of the machining process, including the choice of tool; feed and speed of the tool; machine geometry; and environmental conditions. This irregularity consists of high and low spots machined into a surface by the tool bit or a grinding wheel.

  • How Accurate Is Your Machining Center?

    Virtually every machine tool builder lists, as part of a machine's specification, accuracy and repeatability figures. What's generally not given is the method used to arrive at the figures. Though these methods are defined in linear positioning standards, not all builders use the same standards.
