Is it possible to connect to b&k 4514 accelerometer in ardunio . It aslo need 20mA current for the accelerometer . Please tell me how to get the data and write the data in sd card .As I am new to ardunio programming. some code would really help and also tell me which bnc shield i should use for connecting the accelerometer to the ardunio.
Sure, why not.sk22:

OK. Hmmmm, just what voltage would that be at ? How many accelerometers ? It's usually helpful if you'd bother to take a minute out of your busy schedule to post a link to the unique items that you're asking "us" to help you with.sk22:

Now why don’t you Google “arduino data acquisition” and see what you get. Afterall you’ve not told “us” any of the important requirements; how many channels, the sample rate/channel, the timing accuracy, the range of signal levels, the needed resolution, the needed accuracy, etc, etc.
BNC shield ? Is there one ? Why would you need a BNC shield ? :? How many BNC inputs should it have ?sk22:

the accelerometer i am is this

only one accelerometer i have to use
I need to take 10000 samples in 1 sec

Wow, why do you need that many samples. This sounds like a school project…
More importantly 10k sa/sec and writing them to SD isn't possible w/a "normal" (328/32u4/Mega) Arduino, at least not at full resolution.codlink:

Which ardunio will let me take 10k sa/sec and writing them to SD ??
Which ardunio shield is compatible with the b&k 4515 accelerometer ??
the sensor is this http://www.xscala.com/rentals/pdf/4514B001_bp2066.pdf
8 bit AVR chips aren’t going to do it. Research Arm mControllers like the Teesny3 or the DUE.
Research?
Sounds like work…
At 100mV/g and typical accelerations (you STILL haven’t given us a clue what range and accuracy you need - are you measuring a mountain moving or a rocket?) , you will need to make a custom interface board with some gain to it, and the necessary stable bias supply; there is no standard shield that does what you need, other than the prototype shield.
If you want people to help, please provide all the information that we may need, and let us know what you have already done.
