Floating ball water level sensor is a kind of simple use, low price, so it is widely used. Up to now, there are still many people using floating ball, so * * * mainly introduces some characteristics of floating ball.
Floating ball sensor has large volume, loose structure, large installation space, complex installation design, and increased installation cost. Floating ball water level sensor is easy to produce dirt after a period of time, and the structure of the floating ball is loose and complex, so it is more difficult to clean thoroughly. Therefore, the floating ball sensor is not suitable for use in food machinery, and the generation of dirt can lead to not meeting the food hygiene certification standards.
Floating ball is based on the principle of liquid to magnetic floating ball, so the accuracy of liquid level control is not high, easy to be affected by water level, debris, weather and other factors. There are magnets in the floating ball, magnet adsorption impurities in water, forming dirt after a long time, resulting in the increase of the weight of the floating ball, affecting the accuracy of water level detection.
Non-contact capacitive water level sensor has the characteristics of small volume and convenient installation. The big advantage is that it can directly detect the liquid level from the outer wall of the container, which belongs to the non-contact detection, and can be used to detect drinking water, drinks and other edible liquids. However, both the material of the container and the wall thickness of the container are required, and the container must be made of non-metallic material. Moreover, the capacitive water level sensor has higher accuracy and reliability compared to the floating ball sensor
