Load cell with High Resolution and Higher sampling rate

Dear Friends

Can you help me in selection of force/weight sensor with very high resolution, which can take more than 30 samples per second and 1 milligram resolution.
Thanks in advance for selection.

The output of a strain gauge is continuous, so if your electronics can process 30 samples/second, you have 30 samples/second. As far as the resolution, what is the greatest weight you will need to measure; in other words, what is the range of the measurement?

Dear Friend

Weight of the sample is 10 mg. If you have idea give me the name of company where should i contact?

Dear Sanjay,

The UNIPULSE F370/F371 strain gage indicator has 2000 updates per second (33 per second). Smallest strain gage sensors I have seen are 1kg. The F370 (only one I have seen) would resolve to 0.0001 kg (0.1g)
There are some force restoration units (Sartorius, Mettler, A+D) that can resolve in milligram range, but speed is not high enough for your application.

Hope this helps.
