Conductivity level sensors are widely used in industries that require accurate and reliable level measurements of conductive liquids. These sensors operate based on the principle of electrical conductivity, providing continuous level monitoring and control. In this comprehensive guide, we will explore the working principles, features, applications, and benefits of conductivity level sensors.
Conductivity level sensors operate by measuring the electrical conductivity of the liquid being measured. The sensor typically consists of two or more electrodes, usually made of stainless steel or other conductive materials. When the electrodes are immersed in a conductive liquid, an electrical circuit is formed. The conductivity of the liquid affects the electrical resistance in the circuit. As the liquid level changes, the conductivity between the electrodes varies, leading to changes in the electrical resistance. This change in resistance is then converted into an electrical signal, which is used to determine and indicate the level of the liquid.

Multiple Electrode Configurations: Conductivity level sensors offer various electrode configurations, such as single-point probes, multiple-point probes, and cable-based designs. This allows for flexibility in selecting the most suitable sensor design for the specific application and tank geometry.
Adjustable Sensitivity: These sensors often provide adjustable sensitivity settings, enabling fine-tuning of the detection threshold for different conductivity levels and liquids.
Temperature Compensation: Some conductivity level sensors feature temperature compensation capabilities to account for variations in liquid conductivity caused by temperature changes, ensuring accurate level measurements.
Mounting Options: They can be mounted externally on the outside of the tank or vessel, or installed internally through a threaded connection or flange, offering versatility in installation and compatibility with different tank configurations.
Output Options: Conductivity level sensors provide various output options, including analog signals (4-20mA, 0-10V) and digital signals (Modbus, HART), facilitating seamless integration with control systems and data acquisition devices.
