In weigh scale application can i use load cell (ranges 10kg to 100kg)
for measure below 5kg?
whether it is possible? my weigh scale application for only measure
Food products 0.1 to 100kg.
Good load cells are astonishing. They typically have resolution,
linearity, and stability in the parts-per-million range. A decent 100
kg load cell with good electronics will be accurate to a couple grams.
Of course, the smaller the full-scale range, the better the low-end
resolution.
Note that load cells must be zeroed ("tared") and calibrated (using a
standard weight) regularly. Their as-purchased accuracy can be as bad
as several per cent off.
This is interesting: buy, say, 25 small bags of potato chips and note
the advertised net weight. Now weigh them. You'll usually find that
none are underweight, and rarely are they more than a percent or so
over, even though a single chip may weigh several per cent of the
total. They way they accomplish this is clever and complex.
