Metamotion C sensor 6axis

in General
Hi,
I have bought meta motion C sensor with 6 axis to measure our machine movements. I have tested the sensor in the normal environment , working fine, no problem.  When I use the sensor in the machine, it has lots of noise. I would like to do the filtering techniques to remove the noise, unfortunately I don't know maximum threshold for normal movements and noise. could you please help me to figure out at what frequency range the noise will start. So that I can remove that noise.

Many thanks

Kind regards
Malar

    What kind of motion does the machine make?  Also, please post the recorded data that showcases the noise.

    We have put the sensor into two different mass finishing machines. one of them is vibration trough (speed is around 25rpm) in which the sensor gave a circular motion. There were lots of noise and vibration involved in the process. For the second machine a centrifugal machine (around 200 rpm) where a spiral motion except to be observed, only noise invoved.

    Put images on an image hosting site like Imgur.  Also, please include the actual sensor values and let us know how fast you are sampling the data.

    Please find the graphs of Acceleration and Gyro (both sampling rate are set as 100 Hz) collected from vibration trough machine

    Hi Malarram,

    In order for us to figure out what frequency range your noise is in exactly, we would have to work with your data (which requires you to setup a support contract with MbientLab). However, I can suggest using a low-pass filter of some sort as a good first step. I think you will see that a lot of your noise will be removed with that alone. After applying a low-pass filter, you can look to perform an FFT and use frequency domain filters.

    Also, if you have a MetaCloud subscription and upload the data to our service, you can apply several useful filters automatically and visually inspect your data.

    Thanks,
    Yu
