Description

Body 2, Weight Measuring Mechanism 3, Analog Sensor 4 Besa, Analog-to-Digital Converter 5, Block 6 Control, Digitizer 7, cyNiMaTop 8, Unit Controller 9 Dose, Single Vibrator 10 Time Pulse 11 Converter And, Capacitive Sensor 12 Control 13 Drive Control 14 Saw, tatel 2. The capacitive sensor 12, the one-shot 10 and the time-pulse converter 11 constitute the lead unit T5. The operator setpoint 9 enters the signal Start of the cycle in block 6 of control and in unit 13 of the control 10) with water 14. On this signal, node 13 acquires the control signal to drive 14 of the feeder 2, which starts moving. The control unit 6 outputs control signals to the analog-digital I converter 5, to the one-shot 10, counter 7, and summer 8. The signal from the output of the analogue, or four weight sensor 4 is fed to the input of the analogue-digital. Converter 5, from the output of which in the transformed form goes to the meter 7. In the counter 7, the input pulses are summed up. The sensor of the flow sensor 12 is fed to the input of the one-vibrator 1.Q, from the output of which a rectangular pulse is taken, whose duration is proportional to the performance of the conveyor /, and is fed to the input of the time-to-pulse converter 11. Time-to-pulse converter 11 converts the duration of the input signal in a sequence of pulses so that the number of pulses from its output to the input of the adder 8, is equal to the lead signal.
