load cell interfacing

[anboli]

hi to all,

i having a small doubt, i need to measure a weight of one given platform, measurable weight is around (200kg - 300kg), which area is around 3m*3m size platform?

can i go with single load cell or need to use more than 1? could anybody suggest?

I think if u find single load cell with such capcity then it will be easy for u using centre of gravity. and u must have to use instrumentation amplifier for further circuit

A lot of ADCs could be directly interfaced with load cells.
take a look
