Fantini Cosmi A70 (Open-Closed Tanks) Level Switch

What is a Level Switch?
A level switch is a device used to detect the level of a liquid or solid in a container or tank. It is a type of sensor that can determine the level of a substance within a specific range and can be either float-based or capacitive.

Float-operated level switches use a floating element, such as a float, which moves up and down with the liquid level. As the float rises or falls, it activates a mechanical switch or a sensor that sends a signal to a control system. This type of level switch is commonly used in water tanks, wastewater treatment plants, and other applications where continuous monitoring of liquid levels is required.

Capacitive level switches, on the other hand, use an electric field to detect the presence of a substance. These types of level switches are typically used in applications where the monitored substance is non-conductive or where using a float or other mechanical element is impractical.

Where Are Level Switches Used?
Level switches can be used across a wide range of industries, including chemical processing, oil and gas, food and beverage, and water treatment. They provide a reliable method to monitor and control the level of a substance in a tank or container, making them an important component of many process control systems.
