STRING WEIGHT SENSOR

摘要

Application: the invention can be utilized within an automated system of control of the technological process of single crystal growth. Essence of the Invention: two boards are placed under a hermetic casing; one of them rotates along with the weight sensor, as the other remains static. An optoelectronic couple (that contains an LED and a phototransistor that are placed coaxially) is placed on top fo the boards. Signal is transmitted to the comptuer via the aforementioned optoelectronic couple. Technical outcome: by utilizing the string weight, higher measuring precision and higher sensibility (that allows automated crystal growth from a seedcrystal) can be achieved.
