With the continuous improvement of mechanization, the control system can be said to become more and more important, and the control system of the dry mortar production line is mainly through the sensor to achieve the control of the entire production line.
1. counterweight sensor: used to measure the weight of the mixture for dose control.
2. dry mortar equipment material level limit sensor: using capacitive material level sensor to detect the storage bin material level limit position.
3. Position sensor: using photoelectric sensor to detect the opening and closing status of each valve opening.
The working principle of the level sensor is that the inductor rod is extended into the bin to detect the electrical capacity between the inductor rod and the bin wall (as the electrode to ground) (the capacitive medium is the material), the inductor rod is covered by the material then the capacitance is gradually increased, when the set value of the control circuit inside the switch is reached, the control circuit generates high frequency resonance and sends out a resonance signal to turn into a switch action.
The electrostatic capacitance level meter is equipped with a sensitivity adjustment knob, dry mortar production line to adjust when the material changes; in addition, its output contact can be delayed 0 ~ 105 action to prevent false alarms due to accidental factors.
