About vibration measurement & ADIS16006

Question

Hello,everyone: 
 we are working on a vibration measurement project for oil tank of transformer. 
 Our main parameters show as following: 
 Sensor type:MEMS; 
 BW: 2kHz or more; 
 Resolution:4mg/LSB or higher; 
 FS:±5g or more; 
 Noise: rms< 20mg. 
 Q1:Colud you recommend one sensor to me? Or will ADIS16006 satisfy my parameters? 
 Q2:The difference between ADIS series(Industry application?) and ADXL MEMS series(for consumer electronics?)? We have tried one MEMS of ST,but failed because of bad frequency responce. 
 Q3:If setting the BW=2.26kHz,then I should sample at 4.52kHz or what? 
 Thanks in advance for any reply. 
 Best Regards.

for A2:It is the best case if BW>=2kHz,but we may have to make a compromise, for example, 1.6kHz BW. Considering that the ADXL350 is much cheaper than ADIS16006, we are afriad that the performance of ADXL350 is not as good as ADIS16006. 
 NevadaMark: With the information you have provided, you might want to try both of them out, but I think that you will find the ADXL350 package will be more commonly used by newer products in the future, if you want to be able to leverage newer solutions in the future. I can't comment on what those solutions might look like at this time, but I figured the package insight would be worth knowing on its own. 
 for A4:I mean for that the application examples and AN of ADIS16006 are so few we can find from the Internet. May your commanpy have some appication example or AN, and so on? 
 NevadaMark: A lot of our customers prefer to not post what they are doing, so I would hesitate to assume that the web represents the user base. What you are doing makes sense, but your success is also going to be influenced by how well you can use the sensors to track whatever vibration attribute you care about. 
 
 I hope that this helps. If our posts have earned this, our admins would greatly appreciate you closing this discussion by assigning the most appropriate post with Correct Answer . If we haven't earned that yet, we look forward to further clarification. No problem either way! Thanks!
