Mr. Lassen, Regarding Piezo, or strain gauges to determine
immbalance, the cost to measure in this manner would be
more labor intensive, and would have no advantage over
methods currently employed. I have three balancing machines
in various categories of weight, and one portable unit for field
work. They incorporate load cells / transducers, and are excellent
for plane separation, couple, and force factors.
