Embodiment Construction
[0031] image 3 It is a circuit schematic diagram of a preferred embodiment of the present invention. combine image 3 : Transformer T, rectifier bridge BR, first and second capacitors C1, C2 and Zener diode DW form the described DC power supply 10, which provides the described DC voltage Uc for the circuit system; the described DC voltage Uc The positive end is connected to one end of the second, third, sixth, and eighth resistors R2, R3, R6, R8 in the circuit system, one end of the relay J, and the negative pole of the fourth diode D4; The line ground wire E mentioned above is connected.
[0032] Ground electrodes AE are located at the bottom of vessel AV, below the low water level D, which is also connected to line ground E. If the container AV is made of metal, this electrode can be omitted, but the metal container must be connected to the ground wire E.
[0033] The third capacitor C3, the first diode D1, the first, second and third resistors R1, R2, R3 and the first ...

The invention discloses a noise-type water level control device, comprising a DC power supply 10, an amplifier circuit 20, a detection circuit 30, a comparing circuit 40, an executive circuit 50, a grounding electrode AE, a low water level electrode AD, a high water level electrode AG and a container AV. The invention is characterized in that the noise signal Un in water is adopted to automatically control the water level in the container AV, and the noise signal Un is in an open-circuit state during a water feeding process; the noise signal Un is in a circulation state during a water using process, and is connected to the amplifier circuit 20; when the noise signal Un is in the open-circuit state, a make contact DH of the relay J is disconnected, a break contact DD is closed, a load RL is communicated with AC 220 V; when the noise signal Un is connected with the amplifier circuit 20, the make contact DH of the relay J is closed, the break contact DD is disconnected, and the load RL is disconnected with the AC 220 V. Because the electrode is only provided with the noise current in water without additional DC or AC current, thereby the electrode is not scaled and rotten, the device is reliable and stable in operation.
Description
technical field [0001] The invention relates to a noise type water level control device, in particular to a water level control device which uses noise signals in water to automatically regulate the water level. Background technique [0002] Water level control devices are widely used automatic control equipment. Among them, the electronic water level control device has a large number of applications in the fields of industrial and agricultural production, environmental protection and daily life because of its advantages of small size, low cost and convenient installation. The basic configuration of the electronic water level control device is as follows: install three sensing electrodes in a water container and apply a DC voltage between the electrodes. When there is water between the electrodes, there is a DC current flowing between the electrodes. In the two different cases of no direct current, the water level is automatically controlled.
