The float switch usually controls the operation of the submersible pump, which helps to measure water in the dug well. from a well<\/a>, or from a closed tank. Float switches have multiple functions and designs, and can therefore be used for any liquid.<\/p>\n What tasks do you perform?<\/strong><\/p>\n The main task of the float switch is to start the pump between two water levels. Using a float switch can avoid the so-called dry running, and its use also helps to achieve a preset water volume. The float switch can be used to empty or fill the tank, depending on the setting.<\/p>\n What types are there?<\/strong><\/p>\n In addition to very simple float switches that can be used for water or well water, there are also devices available that for sewage<\/a>, liquids containing solid impurities, and liquids contaminated with oil. Float switches for pumping special liquids are also available, which can be used for acidic and alkaline solutions.<\/p>\n Structure of the float switch<\/strong><\/p>\n The outer casing is usually made of polypropylene. This is completely sealed waterproof. Thanks to the material and the sealing, the device is completely protected against dust and can operate continuously underwater at depths of more than 1 meter at ambient temperatures between -10 \u00b0C and 60 \u00b0C.<\/p>\n Inside the device there is a microswitch, which is activated mechanically by a suitable lever, using a ball. The ball is influenced by the tilt, i.e. where the float switch is at the water level.<\/p>\n Two materials provide insulation for the electrical cables inside, neoprene and PVC. The advantage of neoprene over PVC is that while PVC is a stiffer material, neoprene is more resistant to physical effects and has a better coefficient of expansion. In the case of chlorine-containing media, neoprene is resistant and does not react with the media, while chlorine is released from PVC.<\/p>\n What should we consider when choosing?<\/strong><\/p>\n Before choosing the right float switch, we should definitely consider the purpose for which we want to use it, and also the liquid in which we want to use the device. Let's check if we have any special needs. There are also pieces available on the market that are specifically suitable for industrial use and can be easily used in thicker liquids. It may also happen that someone is looking for a float switch that they want to place in a narrow tank. Today, this can also be solved, as the range of float switches is wider these days, and everyone can find a piece that is suitable for them in terms of size and performance.<\/p>\n These would have been the functions, advantages and operating principle of the float switch, if further for articles<\/a> If you are also curious about the topic, visit my website next week, when we are waiting for you and all interested parties with another interesting topic!<\/p>\n![\"\"](\"https:\/\/magyarendre.hu\/wp-content\/uploads\/2019\/02\/olive-oil-601487_1920-1-1024x819.jpg\" "\\"\\"")
