Hi guys, @joker: no, i mean G's
application for this is to measure the recoil of a large caliber rifle, that's why i need the range and crazy sampling frequency.
Sparkfun has a single axis 250G sensor but it's sampling rate is at 300Hz or something... the recoil only lasts for a ms or so hence i'd probably completely miss it at 300Hz.
Tri-axis would be perfect, but i'm afraid high sampling frequencies and lots of data (3 directions instead of 1) aren't going to be friends. Nor do i expect 3 axis to be friendly on my wallet
@waltr, i found this; http://www.vibrametrics.com/downloads/Individual%20Spec%20Sheets/Model%201000%20Series.pdf
it says it has a broad frequency range, does this also mean it outputs it's data at said frequencies? e.g. I don't want it to measure a 20kHz vibration and the transmit the data that it is sensing a 20kHz vibration at 500Hz, i want the actual G's!
