Level Switches, Float Switches & Sensors

Level switches are critical components in a wide range of industrial and commercial applications. These devices are designed to monitor changes in liquid or gas levels and flow rates, enabling precise control and efficient management of systems and processes. Their reliability and accuracy make them essential in ensuring safety, preventing overflow or dry running, and maintaining optimal operational performance.

What is a Level Switch?

A level switch is a versatile device used to detect the level of a liquid or solid material within a container, tank, or silo. When the material reaches a predefined level, the switch activates to trigger an action, such as sounding an alarm, controlling pumps, or opening and closing valves.

Level switches are essential in applications where maintaining a specific level is critical. They are commonly used in water treatment plants to prevent tank overflow, chemical processing industries to handle hazardous substances, HVAC systems to monitor and control fluid flow, and food manufacturing to ensure precise ingredient levels. Modern level switches are available in various designs, such as capacitance, ultrasonic, and conductive models, providing tailored solutions for different environments and materials.

What is a Float Switch?

A float switch is a specialised type of level switch that uses a buoyant float to detect the level of liquid in a tank or container. As the liquid rises or falls, the float moves with it, triggering the opening or closing of an electrical circuit to activate the desired action, such as starting or stopping a pump.

Float switches are commonly used in water tanks to control filling and prevent overflow, sump pumps to activate automatically as water levels rise, and liquid storage systems to maintain proper levels in industrial and domestic applications. These simple yet reliable devices are valued for their ease of use, cost-effectiveness, and versatility across various environments.
