Other Parts Discussed in Thread: TIDA-00508

Hi TI folks,

  I am looking for a solution from TI, it's a 0.1°-accurate dials with TI’s sensing technology. Please advise.

  By the way, I found TI already have a similar solution, but it's only 1°-accurate dials, below is the video link from TI website:

Best regards.

    Hello Jiang,

    There are two main requirements for improved accuracy - improved mechanical accuracy of the assembly and improved calibration. Regarding the mechanical accuracy - you will need to ensure that the system mechanicals are sufficiently robust and stable. For example, you will need to ensure that the Z height (the distance between the target and the sensors) is well controlled.

    As for the calibration, one of the accuracy limitations for TIDA-00508 is that the calibration process used limits the overall accuracy; you will need a system to calibrate your system. You can also consider using an additional look-up table to provide an improved correction.
