The working principle of stainless steel float ball is direct and simple. Usually, one or more reed switches are set in the sealed non-magnetic metal or plastic tube as needed, and then the hollow float ball with an annular permanent magnet inside is fixed at the relevant position of the reed switch in the rod diameter, so that the float ball floats up and down within a certain range, and the magnet inside the float ball is used to attract the closing of the reed switch to generate a switch action to control the liquid level. Normally open and normally closed are the states when no liquid is injected. The connecting rod float ball liquid level switch is widely used in liquid level control and alarm in various industries such as electronics, chemical industry, water treatment, etc. The connecting rod float ball liquid level switch is a customized product. In order to facilitate the correct selection and customization, when the customer orders, please inform the specifications of the junction box, connection specifications, material characteristics, float ball specifications and related component specifications, body length, action mode, i.e. normally open or normally closed, etc.; at the same time, the use temperature, pressure, specific gravity, acid and alkali resistance and other characteristics of the measured liquid should be informed, so as to select a float ball of suitable specifications.
