Best Way to Mount a Raspberry Shake to a Concrete Ceiling

Technical Support

Hi everyone,

I’m looking for advice on the proper way to mount a Raspberry Shake to a concrete slab ceiling for structural monitoring.

  • Is there any downside to doing this in terms of sensitivity, orientation, or data accuracy?
  • Any recommended methods or mounting materials to ensure good coupling and vibration isolation?
  • Would ceiling mounting introduce any issues for calibration or long-term stability?
  • Right-side up or upside down?

Appreciate any suggestions or experiences you can share — thank you!

Hello ajgnet,

There shouldn’t be any issue regarding the objective you want to achieve, even if I think this is the first time I am reading such an application. Some recommendations:

  • don’t install it upside down. The best solution would be a (metal) bracket solidly connected to the concrete slab ceiling, with the Shake located on the bracket
  • make it sure it’s as levelled as possible, like you would for a “classic” floor installation
  • there shouldn’t be issues regarding calibration
  • if possible, avoid air drafts since ceilings can be more exposed, as they could introduce unwanted “noise” in the collected data

Again, as this is a first, the only other advice I can give is to experiment and check the results! If possible, try a short comparison test with a floor or wall mount to see how the instrument performs.

Honestly, we’re very curious about the data you’ll record, hoping it will be useful for your monitoring purposes.
