Michael, as I read it Ijaz wants to measure a moving vehicle, with static sensors mounted on the road. Is that right Ijaz ?

You need fast data acquisition and quite a lot of signal processing to get a decent reading in the presence of the vehicles vertical accelerations.

You have around 150mSec to make a single reading of an axle, then probably 50-75msec gap, then another 150 mSec. should be quite doable. I think you'll have to sample very fast, so the sigma/delta converters aren't suitable for doing the job, despite the built in bridge drive. So you need to do the bridge drive yourself, not too hard.

I doubt you need an AC bridge for this, but it would give you very good signal/noise ratio.
