A level switch is a control device used to detect specific high or low levels of liquids or solids in tanks, vessels, or silos. When the material reaches a preset point, the switch outputs a signal to control pumps, valves, or alarms. Level switches are available in various technologies such as float, capacitance, vibration, and ultrasonic, and are widely used in industries including oil and gas, water treatment, chemical processing, food and beverage, and power generation for safe and reliable level control.
