Then Pass The Conduit Through One Or More Float Balls With Magnetic Material, And Use Fixed Double Rings To Control The Float Ball And The Magnetic Switch In The Relevant Positions. The Float Level Switch Is A Liquid Level Control Device With A Simple Structure And Easy To Use. It Does Not Require A Power Supply And Has No Complex Circuits. It Has The Advantages Of Being Smaller Than Ordinary Mechanical Switches And Having A Long Working Life. Working Principle: The Liquid Level Sensor Mainly Consists Of A Magnetic Switch And A Float Ball. There Is A Magnetic Material In The Float Ball. One Or More Magnetic Switches Are Set In A Sealed Non-Magnetic Metal Tube Or Plastic Tube. As Long As The Material Is Correctly In The Shape, It Can Be Used With Any Liquid Or Pressure Or Temperature. It Is Widely Used In Shipbuilding Industry, Generator Equipment, Petrochemical Industry, Food Industry, Water Treatment Equipment, Dyeing And Finishing Industry, Hydraulic Machinery, Etc. Be Widely Used. As The Float Rises Or Falls With The Liquid, The Contact In The Ball Near The Beginning Of The Magnetic Is Used To Produce An On And Off Action For Liquid Level Control Or Indication (When The Float Approaches The Magnetic Switch, It Is On; When It Leaves, The Switch Is Off) Open)., Weight: 0.03086471668 Pounds, Manufacturer: Butyge
