Understanding Level Switches: Types, Applications, and Benefits
Level switches are essential instruments used to detect and control the level of liquids, solids, or slurries in tanks, vessels, and silos. These devices play a crucial role in various industries, including manufacturing, chemical processing, water treatment, and food production, by ensuring optimal operation and preventing overflow or dry-run conditions. Types of Level Switches 1. Float Level Switches Float level switches use a floating element that rises or falls with the liquid level. When the float reaches a specific height, it triggers a switch to open or close a circuit. These switches are commonly used in water tanks, sump pumps, and fuel storage applications. 2. Conductivity Level Switches These switches operate based on the electrical conductivity of liquids. They consist of multiple probes that detect the presence or absence of liquid between them. Conductivity level switches are widely used in chemical processing, wastewater management, and boiler systems. 3. Capacita...
