I had a similar project and found a great solution. I used a high speed DA system for load cells from TEAC. Model TD-SC1. It has a DA rate of 20-khz. It also has a 0-10 volt output also at 20-khz. I connected my load cell to the TD-SC1 and the output of the TD-SC! to an MCC USB-230. Then used DASYlab to monitor the USB-230 and do what i needed to do with the signal. i was able to set up scaling modules to calibrate the 0-10 volt output from the TD-SC1 so that i got proper load readings from USB-230. It worked really well.
