Level sensors provide numerous advantages, including:

Continuous and precise level measuring improves process control.

Preventing overflows and underflows ensures safety and efficiency.

Versatility in varied materials and environments.

Reduced waste and improved resource management.

There are 4 types of Level Switches based on the nature of measurement.

Float Switches: Use a buoyant float to open or close a circuit when the liquid level changes.

Conductive switches detect levels based on the liquid’s conductivity, making them excellent for water or other conductive liquids.Optical switches use light beams and sensors to detect the presence of liquids at a predetermined level.Capacitive switches detect level changes based on capacitance changes in the surrounding medium

A level sensor’s primary function is to enable real-time, continuous monitoring of material levels, allowing for accurate management of processes and inventory, preventing overflows, and assuring efficient operation in a variety of applications.

A level switch detects the presence or absence of material at a particular point by processes such as flotation, optical detection, or conductivity. When it reaches the predetermined level, it initiates an action such as pump activation or valve opening/closure.
