![]() ![]() ![]() If a float switch with the switching function normally closed is being used, the contact leaves move away from each other and the current circuit is interrupted as soon as a magnetic field is applied. Current can then flow through the contact of the leaves and a switching signal can be detected. If a float switch is used with a reed switch with the switching function of normally open and a magnetic field is applied, the contact leaves move towards each other. These contact leaves move towards or away from each other due to a magnetic field. Adjusting collars to limit the movement of the float on the tubeĪ reed contact, also known as a reed switch, involves contact leaves that are located inside the hermetically encapsulated glass body.A hollow float body with an enclosed magnet.In its simplest form, a float switch is made up of the following components: Modern float switches have a very sophisticated design. A float-based measurement technology uses the movement generated by the level change to measure the level. Due to its low density and buoyancy, the float is raised when the level of the liquid rises and lowered when the level of the liquid falls. The measurement technology for level is based on buoyancy of a hollow body, the so-called float. Bypass level indicators are mounted on the side of the tank and are often combined with a magnetic display for a visual level indication. ![]() Depending on accuracy requirements, level sensors are available with reed chains or magnetostrictive measuring systems. Because they are simple, universally applicable and exceptionally reliable, float switches have a very wide range of applications. Float switches are used for the point-based limit level detection of one or several levels. With float-based measuring systems for level monitoring, a distinction is made between float switches, level sensors and bypass level indicators. What float-based measuring systems are there for level monitoring?
