Automatic recording quartz spring balance with an image sensor
Kei Hayashi, Masaru Nakamura, Koji Miyauchi, I. Yamamoto · Review of Scientific Instruments · 1981
An automatic recording quartz spring balance is improved by using image sensor techniques. Two kinds of arrangement of the image sensor are examined. The weighing error is less than 0.15% for the maximum load. Stability against a zero point shift is excellent. Merits of this balance are discussed in comparison with previous automatic recording balances. Especially the balance system is simple in mechanism.
