How can a scale count something? I thought scales were only good for weighing things?
Good question. A counting scale is, in fact, a weighing scale, but with two major differences. First, the load cell (the electromechanical device that translates pressure to weight) is about a hundred times more sensitive than the type you might find in a standard weighing scale. Secondly, it is the special circuitry inside a counting scale that allows it to interpret weight as a piece count. The scale’s microprocessor compares the known weight of the sampling with the weight of the total lot on the scale and displays the corresponding count.
