Abstract

PURPOSE: To accurately detect the movement condition of powder and grain, by detecting the charge on electric insulation part provided at a part of the delivery tube due to movement of powder and grain.
CONSTITUTION: When powder and grain move in the conductor delivery tube 1 grounded, the insulation part 1a provided at a part of the delivery tube 1 is charged up with the friction with powder and grain. This charged potential is detected via the detection electrode 2 opposing with the part 1a, and it is the powder and grain movement detection signal with the peak value limit high input resistance circuit 3, high band amplifier 4, rectifier 5, and comparator 6 in which reference voltage is set depending on the movement of powder and grain to display the movement of powder and grain on the display unit. With this constitution, the condition of movement of powder and grain can accurately be detected.
