Float level switches | Choosing the right level switch
Float level switches are based on a simple principle: the combination of a float and a mechanical or magnetic switching device (reed switches). Naturally a float placed in a liquid tends to stay at the surface, this is the effect that is exploited here by detecting the displacement of a float when the liquid surface reaches its height in the tank. There are 3 main types of float level switches: The "suspended" level switch type, which is simply made up of...
