Level switches | Choosing the right level switch
Level switches, like level sensors, are mainly used to determine the filling level in tanks, silos or storage containers. While the two terms can be considered almost synonymous, there is a real technical difference between them. In contrast to level sensors, which continuously measure the change in level, the level switch only indicates whether or not the level has reached a certain height. It is a one-time measurement. A detector therefore does not send a...
