The Mitutoyo AT715 and me

It’s been a while since I’ve posted and that’s primarily because I’ve been working on a project. I have to keep some of the details to myself but I will show some pictures of the prototype that has taken me a couple of weeks to design and build.

The precursor to my project, the Ultigage.

The device uses the AT715 from Mitutoyo and what an interesting device it is. With a resolution of .0005mm and an RS485 interface, it is an ideal device for measurement and for use on machines. The device, which uses magnetic induction, uses 30ma whereas a lot of other glass scales use up to 250ma @ 5v. This is a pretty cool device.

Well, I can’t get into a great deal of detail because the product I have in mind may compete with other gaging companies like Gagemaker with a universal, handheld, high precision, digital gage that has active, rugged and dynamic probes. The images shown are that of a rough prototype, I’m not normally secretive but once one is built in a few weeks I can post some images of the more refined version.

After all, this is simply a post for posterity. 🙂

  1. hi,

    I would like make the same project, could you tell me the pinout of At715?
    this scale use rs485 standard, or there are some modification ?
    what is the format of data ? you only read At715 or you can write also ?

    good job
    regards
    laurent

  2. Hello,

    I am interested in doing this project but, perhaps with a Arduino. I read online that the pinout of the At715 is: pin 1 ground, pin 3 +5V, and pin 10 Data, please confirm this. What is the format of the data (ie is there a beginning byte, how many)? Thank you

    wen
