摘要

The impedance of a zone above bulk material in a bin is measured as a probe is reciprocated toward and away from the material in this zone. The direction-change location of the probe which corresponds to the measured impedance reaching a set point value, is detected and utilized to provide the control signal for automatically replenishing the material in the bin.
