It is not a coincidence that, today, float switches still represent probably the most commonly used principle for level monitoring. But so how exactly does a float switch really work?<br\/>Float switches, in a simple mechanical form, have been used for the control of water flows in mills and fields for centuries and today still represent probably the most frequently used technology. A hollow body (float), due to its low density and buoyancy, lifts or drops with the rising and, respectively, falling degree of the liquid. If one uses this movement via a mechanical lever, e.g. as a straightforward flap control for an irrigation channel, one has implemented a mechanical float switch.<br\/>Modern float switches, needless to say, are used for switching an electric circuit and feature a clearly more sophisticated design. In its simplest form, a float switch consists of a hollow float body with an integral magnet, helpful information tube to guide the float, adjusting collars to limit the travel of the float on the tube and a reed contact situated on its inside (see figure).<br\/>Figure: Selection of reed contacts of a float switch<br\/>So how exactly does the float switch function?<br\/>Reed contacts (see figure) of a float switch feature contact leaves within the hermetically sealed glass body, which move together or aside from each other when a magnetic field is applied. Regarding a float switch with a reed connection with a normally open function, on applying a magnetic field, the leaves are brought into contact. Once the contact between your leaves is made, a current can flow via the closed leaves and a switching signal will be detected.<br\/>In the case of a float switch with normally closed switching function, the contact or circuit is interrupted on applying a magnetic field. If one selects a change-over contact, the glass capsule will contain three contact leaves, with which, always, a normally closed and a normally open contact are simultaneously manufactured in every operating state.<br\/>Because the contact leaves are under a mechanical preload, a magnetic field must be applied to ensure that the contact leaves close or open as a way to generate the required switching signal (monostability). The adjusting collars fitted by the product manufacturer serve as a limitation for the float body in the right position, to make sure \/ maintain the desired switching signal on achieving the defined filling level.<br\/>So how exactly does one specify a float switch?<br\/>The following parameters ought to be defined:<br\/>Number of switch contacts \/ switching outputs<br\/>Position and function of every switching output<br\/>Guide tube length<br\/>Electrical connection (e.g.  <a href=\"http:\/\/gourmetgatheringspro.xyz\">\u0e40\u0e01\u0e08\u0e27\u0e31\u0e14\u0e41\u0e23\u0e07\u0e14\u0e31\u0e19\u0e15\u0e48\u0e33<\/a> )<br\/>Process connection<br\/>Material (stainless, plastic, ?)<br\/>Note<br\/>As a leading provider of float-based measurement technology solutions, WIKA has a wide range of variants to meet all your application-specific requirements.
