Level sensors | Choosing the right level sensor
In all industrial processes that use reservoirs, silos or storage tanks, you need to know the level of the stored elements, or at least be able to detect significant levels (i.e. a full or empty tank). This is what level sensors and detectors are used for. Although these two terms might seem like synonyms, the two devices are fundamentally different: while a detector indicates whether the level has reached a certain height,  a sensor gives a continuous...
