AEC2-R4 Online Inductive Conductivity Controller

Chlor-alkali plants are a very typical chemical industry. In the chlor-alkali industry, water monitoring is very critical. Many production processes in chlor-alkali plants rely on precise control of water quality. By monitoring the conductivity in water, the concentration of dissolved substances (such as salts) in the solution can be understood, which can help adjust production parameters to ensure product quality and production efficiency. In the chlor-alkali industry, electrolysis is a common production method used to produce hydrogen, sodium hydroxide and chlorine. The efficiency and stability of the electrolysis process are closely related to the ion concentration in the electrolyte. By monitoring conductivity, the solute concentration in the electrolyte can be adjusted to optimize the electrolysis process. Generally speaking, the conductivity range of water quality in chlor-alkali plants will vary depending on the production process, raw materials used, water sources, wastewater treatment and other factors, and the conductivity range covered is also relatively wide.

Daruifuno's AEC2-R4 online conductivity controller is used with an inductive conductivity electrode and can measure high conductivity ranges. Mainly used in the production process of chlor-alkali plants, the conductivity of the electrolyte will change as the reaction proceeds, from a few hundred μS/cm to several thousand mS/cm. The advantage of using an electromagnetic conductivity analyzer is that first of all, its measurement range is very wide, and the matching ASC200 ring conductivity electrode can monitor conductivity up to 2000mS/cm. Secondly, the ring electrode has strong anti-pollution ability, good measurement stability, and strong corrosion resistance. Finally, the conductivity electrode also has a built-in temperature sensor, which can be used with a controller to achieve automatic temperature compensation. Therefore, in a chlor-alkali plant, if you want to measure a high range of conductivity, using this AEC2-R4 online conductivity controller is a very wise choice.

Specification

In a chlor-alkali plant, if the conductivity of the incoming water is monitored, typically the conductivity of surface water, groundwater, and municipal water supplies may range from tens of μS/cm to hundreds of μS/cm. Just use a conventional conductivity electrode based on the two-electrode principle. Daruifuno's ASCK series conductivity electrodes, which have electrodes with K constants of 0.01 and 0.1, are suitable for conductivity monitoring in this kind of water.
For wastewater from chlor-alkali plants, it also needs to be treated to comply with environmental regulations before it can be discharged. For conductivity monitoring of wastewater, conventional two-electrode or four-electrode conductivity sensors can also be used. When a high-range conductivity range needs to be monitored and the water is highly polluted and corrosive, electromagnetic conductivity electrodes are used.
