PROJECT: Determining weight with load cells.
First, I am not an electrical engineer and am not to familiar with circuit boards.
PROJECT: I have a static load, represented by a block. The block has three very short legs (or feet 3/8" diameter each). The feet are located concentricly under the block. Under the feet I place three thin-film force sensors that will be in compression when loaded. The sensors need to be wired in (series? or Parellel?) to a digital read out screen.
GOAL: I would like to read on the digital screen the TOTAL weight of the block when it is set on a smooth, solid substrate and powered on.
1) Is a microprocessor needed?
2) If so, for what?
3) Can all the needed circuitry (for the sensors and the digital screen info.) be put on a circuit board?
4) Can the digital read out device have a button to push that will re-set, or re-calibrate the device back to zero reading and then read the weight of a new load that has been added on top of the original block (without including the weight value of the original block)?
5) Can you explain what circuitry is needed?
I probably have missed a few things, so please fill in the blanks.
Thank you so much for your help..........

Aside from the electronics, here what the "big boys & girls" (METTLER TOLEDO) consider when designing a weighing system. See if you can refine your questions after taking a peek.
