The function of choosing a capacitive water level sensor is not only to meet its own needs, but also to pay attention to the quality of the sensor. The main function of the sensor is to detect and control the water level.

The function of the general capacitor water level sensor is:

1. To detect the target point set in the water tank, a signal reminder will be given. For example: If there is no water in the water tank, a low water level will be set. When the liquid level reaches the position, the signal reminds will be given. It is the same when there is water to prevent overflow.

2. Connect the control board to detect automatic watering when the water tank is not waterless.

Capacitor water level sensors, cheap and small volume. The main detection characteristics are: it can detect fluid levels from the container, mainly satisfied, some users do not want the sensor to pollute the water quality. This feature has greatly expanded the application of capacitive water level sensors.

Although the price of float type is equally cheap, the performance of photoelectricity is more stable than capacitive properties, but the first two need to be installed and used for opening holes in the water tank, and the capacitance type only needs to be close to the outer wall of the container.

Floating ball -type water level sensors are difficult to use in viscosity liquid and liquid containing impurities. Floating balls are easily stuck and causing inaccessibility. The capacitor can be detected only on the outer wall of the water tank, which is very convenient.

Of course, each product has its own advantages and disadvantages. The disadvantage of capacitive water level sensors is that it limits the wall thickness of the container. When the wall thickness exceeds, it will affect the detection, and the capacitance type also limits the material of the container, which is only suitable for non -metaphysical water tanks.
