Does anyone have recommendations for a suitable data logger?
following specs I'm looking for are:
sampling rate of at least 2kHz per channel
as many channels as possible (at least 8 but ideally significantly more, like 24)
at least 10 bit resolution (although ideally 12 or more)
gain on strain gauge signals (using ADC) of ~100 (or more)
able to sample continuously for at least 5 minutes
ideally compatible with some setup that can use quarter bridge wheatstone bridges that are small and reliable
I have actually used the digilent openlogger in the past with some success, although this has been discontinued. One issue I had was that I had to make my own wheatstone bridges when using this which took up a fair amount of space (not ideal), I had to amplify the signal (adding a load of gain amplifiers that took up further space) and I do not know how I would synchronise between openloggers (as they are limited to 8 channels but I would like to have more channels). The data logger would be used to measure strain and should be able to take a bit of bump in outdoor conditions. If this isn't really the right part of the forum or if digilent isn't really the right company, advice for other recommendations of products from other companies would be appreciated.
