Description

In its motion, the reflected glass is a mass beam, the passage through the diaphragm 8 intersects the photodetector 9 installed on the opposite side of the furnace. The signal obtained when the photographic photometer 9 is illuminated enters the time interval measurement unit 10. In addition to the photoreceiver-PIK 9 3 signal, the time int-eval measurement unit receives a signal from the 11 o signal auxiliary signal block, which fixes the position of the drum 3, which is determined. The reference signal, relative to which the time is measured, goes to the block 10 always in one strictly defined a time corresponding to, for example, ach: 1y of the period of - (.:. i.:.aJEHH} of falling beam.

Regulator 12, depending on the ratio of the measured and set time intervals, gives a signal for changes in the consumption of raw materials loaded into the furnace.

This method makes it possible to achieve a high accuracy of maintaining the glass melt level, while the level measurement error does not exceed 0.05 mm at a sensitivity of 0.025 mm. Such a high measurement accuracy ensures reliable level maintenance in the range of + 0.1 mm, which meets the requirements of 1 m technology.
