flottørsensoren

A flottørsensor, or float sensor, is a device used to detect the level of a liquid in a container. It works by utilizing a buoyant object, the float, which rises and falls with the liquid's surface. This movement is then translated into an electrical signal or a mechanical action. The most common type of flottørsensor employs a simple lever system. As the liquid level changes, the float moves a lever, which in turn operates a switch. This switch can then trigger an alarm, activate a pump, or shut off a filling mechanism.

Another variation is the magnetic reed switch flottørsensor. In this design, the float contains a magnet, and as it moves up or down, it passes by a sealed reed switch. When the magnet is close enough, it closes the switch, completing an electrical circuit. These sensors are often found in applications such as toilet cisterns, washing machines, dishwashers, and fuel tanks. They are valued for their simplicity, reliability, and relatively low cost. The specific design and materials used can vary depending on the intended application and the type of liquid being monitored, with options available for corrosive or high-temperature environments.
