Mahr Micrometer Integrates Wireless Data Transmission

Originally titled 'Micrometer Integrates Wireless Transmitting System'

Digital micrometer measures 10 times faster than a standard micrometer.

Mahr Inc. recently announced new Micromar 40EWRi-L digital micrometers with high-speed measuring spindle positioning. The integrated wireless system accelerates the measurement of workpieces while protecting the surface of the test specimens. The spindle makes a 5 mm movement with one revolution of the friction drive sleeve and, according to the company, can be positioned 10 times faster than a standard micrometer. This saves the user time when measuring workpieces with different sizes. The non-rotating system provides a solution for measuring film thickness without twisting and damaging these delicate materials. The 10 mm display and intuitive operating concept support users in production and quality assurance, featuring measuring reliability, fatigue-free reading and simple operation.

 

The digital micrometer is available in eight standard measuring ranges of 0" through 4" in 1" increments (0 through 100 mm in 25 mm increments). Measurement data is transferred to an i-Stick on a computer via an integrated wireless system that does not use data cables. A unique serial number for the instrument is also transferred, so the user knows which instrument made the measurement and when the last calibration was performed.

Using the company’s MarCom software, operators can take a measurement and transmit measuring data directly into Microsoft Excel or into any Windows program via a keyboard code without using external transmitters or cables. The user can also apply the wireless data collection capabilities to existing SPC applications. The micrometer confirms a successful transfer via a message on the display. An integrated radio enables the measuring instrument to be compact and consume very little energy.
