Burkert Fluid Control Systems has developed the MultiCELL Type 8619 multi-channel controller for water treatment, food and pharmaceutical applications. In reverse osmosis systems, the controller can be used for monitoring functions as a flow indicator, to measure the ORP value or percentage retention value. The Type 8619 MultiCELL can also be used for control tasks, such as regulation of the pH value and the dosing of chemicals and ratio control. The modular controller is adapted at the factory to the particular application and customer specifications.
The standard version includes the user interface, mainboard and AC adapter, two analog and digital outputs and two digital inputs. Six slots are available for connecting additional boards. The large, configurable graphic display with backlighting can display up to four readings simultaneously. Further parameters and user-specific pages can be displayed by scrolling. The digital and analog signal outputs enable the transfer of process data and status signals. If more than two of these are needed, an output card with two additional digital and two additional analog outputs can be installed. All process values can additionally be stored on SD cards by means of an optional data logger package for computer analysis using any standard software package.
