Capacitive Level Switches
Capacitive level switches are widely used for point-level detection in various industries, providing reliable solutions for monitoring the presence of liquids and solids in tanks, silos, and bins. These switches operate based on capacitance change, where the probe detects variations in the dielectric constant of the media they are in, enabling them to accurately detect different materials—like water-based liquids, chemicals, and powders. Despite offering a more advanced technology than the mechanical switches that came before them, capacitive level switches are simple devices. They contain a probe and a few circuits, and they have no moving parts. They are maintenance-free, highly durable, and very versatile.
Capacitive level measurement technology allows services to take place and level detection to occur under difficult circumstances. These circumstances could range from having very humid or dusty conditions to having different parts of a system at very different temperatures. With easy installation in systems such as tanks or silos, these switches serve a few important functions. They help prevent the kind of dangerous dry run situations where a pump is running but there's not enough media in the way to do the job. They also help stop an overfilling situation from turning into an emptying situation.
