Hi,

I am looking for a load cell for my application..

I want one with minimum size (<= 2cmx2cmx1cm (lengthxwidthxheight). From what I have read it looks like I might need a miniature load cell... ?

I want to connect this to an ADC so am looking for a mv/V output.. I want to be able to measure 0-5 kg with accuracy upto 50-100 gm which should be possible with a 10 bit ADC..

Also, cost is a important factor as I need to have many of these (~20-25). The ones I looked up online are in range of 7-8$ plus per piece.. I was under the impression that load cells are pretty cheap (under 2$?) .. :bang:

I want linearity to be +-0.3% or less... if anybody has any knowledge of such a part I will be very grateful..

BR,
Prashant
