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...

How to choose this product
level-switch

A level switch, or detector monitors levels in open or closed containers.

Applications

These devices are found in every industrial sector. They also are installed with pumps to prevent them from operating dry.

Technologies

There are different methods of detecting levels within a container. These include the use of floats, pendulums or rotating paddles. Others employ optical, ultrasound, microwave, capacitive or conductive systems.

How to choose

Choice will depend on the liquid or loose solid material whose level is to be measured. Other factors include temperature, pressure, explosion risk, the structure of the container and other aspects of the operating environment.
