A friend of mine worked for a company that went under and I was able to get my hands on this accelerometer:
http://www.omega.com/pptst/ACC786A.html
I want to use it to characterize a motor that might have a bad bearing and to in general play around with it. I have a simple voltage DAQ with a high enough sampling rate to pick up the frequency range I'm expecting the bearing to show in...but I'm having issues trying to find out how to make a simple power source for this thing...
The full description is in the link, but it was it requires a 2 to 10 mA current at 18 to 30V. I've seen some descriptions of using OP-Amps, but I'm not sure exactly what my power requirements might be so I don't know how to select alternative components to run at the voltage and currents stipulated.
Any help or advice would be welcomed.
