SFC PC Process Controller
The Wallace & Tiernan® Systems SFC PC system controls on the basis of a controlled variable (e.g. a flow signal) and an actual value signal which can be an external mA signal.
Thanks to the fuzzy technology, compound loop control with flow rate and access to the controlled process variable (e.g. chlorine) results in significantly improved control. The SFC PC system saves its reactions to control deviations permanently and uses this data as a basis for future control, allowing the control variables to be balanced optimally with the flow and the control parameters.
