Electrode Level Sensor Product

As a electrode level sensor manufacturer, we are making our contribution to manufacturing electrode level sensor for different kinds of applications and industries. Electrode water level sensor is also known as a “Electrode Level Switch” , “Conductivity Level Sensors” and “Conductivity Level Switch”.

An electrode level switch is a type of sensor used to detect the presence or absence of a liquid at a specific level within a container or tank. It operates based on the principle of electrical conductivity. The switch consists of multiple electrodes that are positioned at different heights within the container. When the liquid level reaches a certain height and makes contact with the electrodes, it completes an electrical circuit, triggering the switch to either turn on or off.

The electrodes in an electrode level switch are typically made of materials that conduct electricity. When the liquid covers the electrodes, it creates a conductive path between them, allowing electrical current to flow. This change in conductivity is detected by the switch’s circuitry, which then activates the switch. Conversely, when the liquid level drops below the electrodes, the circuit is broken, deactivating the switch.

We will provide our conductivity level transmitter solutions for you according to your real function and application requirements.

Knowledge about Electrode Type Level Switch

How does Electrode Level Switch Work?

An electrode level switch operates on the principle of electrical conductivity to detect the presence or absence of a liquid at a specific level within a container or tank. Here’s how it works:

Electrode Configuration: An electrode level switch typically consists of multiple electrodes positioned vertically at different heights within the container or tank. These electrodes are made of materials that conduct electricity, such as stainless steel.

Conductivity Principle: When the container is filled with liquid, the liquid acts as a conductor, allowing electrical current to flow. The conductivity of the liquid depends on factors like its composition and impurities.

Circuit Completion: The switch’s circuit is designed so that when the liquid covers the electrodes and completes an electrical path between them, a closed circuit is formed. This allows a small electric current to flow through the electrodes and the liquid, indicating that the liquid level has reached the height of the electrodes.

Switch Activation: The closed circuit triggers the switch to activate. This activation can result in various actions, such as turning on a pump to prevent overfilling or stopping a process to prevent the liquid level from dropping too low.

Circuit Breakage: When the liquid level falls below the electrodes, the electrical path is broken, and the circuit becomes open. This change is detected by the switch’s circuitry, leading to deactivation or reversing the action initiated when the circuit was closed.

The electrode level switch’s operation is straightforward yet effective. It relies on the changes in electrical conductivity caused by the presence or absence of the liquid. This simplicity makes the switch reliable and suitable for various industrial applications where precise liquid level monitoring is essential.

In summary, an electrode level switch uses the conductivity of the liquid to complete or break an electrical circuit, triggering actions based on the liquid’s level within a container or tank.
