Accurate Solution Composition Control for Enhanced Safety and Efficiency

In the chemical industry, the quality of final products, the safety of production lines, and the overall efficiency of processes directly depend on the precise composition of solutions and reactants. Electrical conductivity (EC) serves as a fast and reliable indicator of ionic concentration in chemical solutions. EC sensors play an essential role in production lines, industrial automation systems, and quality control units.

How Does an EC Sensor Work?

An EC sensor measures the electrical resistance between two electrodes immersed in a solution, providing an accurate estimate of the total ion concentration. This value acts as the “electrical signature” of the solution and is directly correlated with the concentration of dissolved chemicals.

Key Applications of EC Sensors in the Chemical Industry

Controlling Solution Concentration in Chemical Reactions: Accurate concentrations of acids, bases, or salts are often critical for desired chemical reactions. EC sensors allow operators to monitor and adjust solution concentrations in real time, without needing to send samples to a laboratory
Monitoring CIP (Clean-In-Place) Processes in the Pharmaceutical and Food Industries: In CIP systems, EC sensors are essential for distinguishing between rinse water, detergent, and sanitizing agents. This real-time differentiation saves on cleaning agents, water, and operational time
Monitoring Industrial Water Quality: In boilers, cooling towers, and heat exchange systems, precise EC control helps prevent corrosion, scaling, and efficiency loss
Separation, Purification, and Recycling Processes: EC sensors are widely used in reverse osmosis (RO), ion exchange, and distillation systems to continuously monitor and optimize the quality of input and output streams
Safety Monitoring in Hazardous Chemical Processes: In processes where even slight changes in concentration can trigger dangerous or undesirable reactions, EC sensors serve as early-warning systems.
