Using the power switch integrated circuit level one controlled circuit sink type

The power switch integrated circuit A features a straightforward design with high sensitivity, ensuring reliable operation. It is part of an automatic liquid level control circuit. When the water level at electrode B drops below 2 feet (0V), circuit A activates. If the water level decreases to 4 feet (0V), the relay KA and KM are engaged, initiating the pump to fill the water tank. Once the water level rises to electrode A, exceeding 2 feet (1.5V), the circuit deactivates, causing relays KA and KM to release, which stops the pump operation.

The described circuit utilizes an integrated circuit (IC) designed for liquid level sensing and control. The primary function of this circuit is to maintain the water level within a specified range by activating and deactivating a pump based on the readings from two electrodes, A and B.

Electrode B serves as the lower threshold sensor. When the water level falls below 2 feet, it generates a low voltage signal (0V), which triggers the integrated circuit A to engage. If the water level drops further to 4 feet, the circuit activates relays KA and KM. These relays are responsible for controlling the pump's operation. Once activated, the pump begins to fill the water tank until the water level rises above the upper threshold set by electrode A.

Electrode A functions as the upper threshold sensor. When the water level reaches this electrode, exceeding 2 feet and registering a voltage of 1.5V, the integrated circuit detects this condition and deactivates the relays KA and KM. This action stops the pump, preventing overfilling of the water tank.

The reliability of this circuit is enhanced by its simple design and high sensitivity, making it suitable for various applications in water level management systems. The integration of relays allows for effective control of the pump, ensuring that the water level remains within desired parameters without manual intervention. Overall, this automatic liquid level control circuit is an efficient solution for maintaining optimal water levels in tanks and reservoirs.As a result of the power switch integrated circuit A, it has a simple circuit, the sensitivity is high, working and reliable. It belongs to the people filling liquid level auto matic control circuits. When the water level in the following electrode B, A 2 feet low (ov), A is turned on, 4 feet low (Ov), pull the relay KA, KM pull, pump up and running, the water tank water; when the water level rose to electrodes a, a 2 feet high ( 1.5V), a cutoff, KA and KM release, the pump stops irrigation.
