Vibration sensor mounting with high pass propertys
Vibration sensor mounting with high pass propertys
(OP)
I am looking for a material / mounting method for a mems sensor to attenuate frequencys below ~10 hzs while passing the high frequency information. Any ideas or link would be appreciated. Thanks, Mick

If I were you I would look at making a high-pass filter on the accelerometer output. Go to this link and you can design your own:

They have a FREE download for basic filter design or you could spend a couple of bucks and go for the high-spec software. The components for these filters are inexpensive and easy to build.
Good luck

take two identical charge coupled accelerometers. Turn one upside down. mount the other on a low pass filter (sold by B&K). T the two together into the back of the charge amp.
Sorry about that, it is a terrible approach, but I have used something a bit similar to this.
Cheers
