IMU for displacement measurement <10cm during 40s

Other Hardware Sensors
1

Hey all,

First of all a happy newyear! My best wishes for 2014!

Untill now I have no experience with IMU or other accelerometer sensors. So before I start buying stuff I'd like to know if a typical IMU is capable of measuring displacements in the range of 0-5cm (up to 10 cm) with an accuracy of 1-2 mm? And this only during 40 s. After the 40 s, it's save to reset the position to 0.

I need to measure the displacement of some components under high tension (3kV) and in a place very difficult to reach. I was thinking of an IMU as sensor with a base station nearby (easier to reach and not under 3kV). Communication by XBEE.

Thanks!

  • accelerations can go up to 60g

Normal range is <30g

prio 1: check if XBEE works in a 3KV environment ...

Good point. I forgot to mention it's 3kV DC which is less likely to cause interference but still...
