Digital Calipers, Indicators Enable Wireless Data Transmission

Mahr Federal wireless data transmission capability is now integrated within its families of MarCal digital calipers and MarCator digital indicators. Both products send data to a small i-stick receiver resembling a USB flash drive. MarCom software eases data acquisition by enabling users to take a measurement and transmit measuring data directly into Microsoft Excel or via a keyboard code into any Windows program, without the need for external transmitters or cables, the company says. Additionally, users can apply the wireless data collection capabilities to existing SPC applications.

Low-power transmitters in these digital calipers and indicators eliminate the need for expensive add-on transmitters that can consume excess power, make gages bulky and interfere with portability, the company says. Each MarConnect i-stick wireless receiver supports as many as eight measuring instruments with a range of 12 m, suitable for most benchtop or workstation applications. The MarConnect integrated wireless interface is active as soon as the i-stick is plugged in, and each caliper/indicator is identified by signal coding in the MarCom software so that there is no signal confusion.

The company’s line of mechanical comparative gages can also be upgraded for wireless data transmission with the addition of a MarCator 1086 or 1087 wireless digital indicator. With the addition of wireless transmitters, digital indicators can help speed part inspection times, reduce the complexity of data collection and improve the quality control process. 


  • 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.

  • Working With Your Working Gage Blocks

    The uses of working gage blocks are as varied as the number of gage blocks in a large set. The working blocks have an intermediate grade and are often used in the inspection or calibration lab, but they may also be found on the shop floor.

  • Composites Machining for the F-35

    Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
