Level switches

In point level detection, a point level switch detects when a certain predefined level is reached. Such a device is employed when it is not necessary to measure every possible intermediate level, as is the case with continuous level measurement. A switching command starts or stops filling equipment such as conveyor or pumps. Point level switches outputting a binary signal can be integrated into a process control system.
Point level detection systems can be used in liquids, pastes, powders or coarse bulk solids.

Typical applications  for level switches are: minimum or maximum detection, leak detection, overfill protection in process tanks, storage tanks, silos and pipelines.
