I've seen these bearings being monitored on a turboexpander at +65krpm using a 100mv/g (0%  dB sensitivity change up to 7- 8kHz) accelerometer with (strong) magnet.

In my opinion this could be improved. What do you think? A more sensitive accelerometer? possibly with a wider linear frequency range and mounted on a pad or stud?
