Adaptive pH Control
CyboCon pH is a special CyboCon package
specifically for controlling pH processes.
MFA pH controller;
• Specifically designed to control pH value loops;
• Controls full pH range with high precision;
• Enables automatic control of acid or alkaline
• Easy startup and maintenance;
• Runs on Windows NT, 2000, XP and Windows 7;
• Interfaces to all major PLCs, DCSs, and HMIs;
• OPC ready;
• Applicable to all process industries.
Comparison of MFA pH and
pH is able to control strong-acid-and-strong-alkaline
based pH systems in the entire pH range. It is not sensitive
to the shape and position variations in the Titration
PID either makes the pH system oscillate near neutrality
or becomes slow and sluggish away from neutrality.
Anti-delay MFA pH Controller
for the pH Process with Large Time Delays
When a pH process is combined with large varying time
delays as well as large inflow rates and pH changes,
the difficulty of this control loop quadruples. You
not only must deal with the large gain changes, but
also the varying time delays. These almost "uncontrollable"
processes now can be effectively controlled using the
MFA pH controller.
MFA pH controller has the combined power
of being predictive, adaptive, and robust. It is adaptive
to compensate for the large gain changes, predictive
to deal with large time delays, and robust to handle
inflow changes, titration curve moves, and other uncertainties.
It is easy to configure, launch, and maintain.
Clean Water is a Precious
Most process plants generate a wastewater effluent that
must be neutralized prior to discharge or reuse. Consequently,
pH control is needed in just about every process plant,
yet a large percentage of pH loops perform poorly. Results
are inferior product quality, environmental pollution,
and material waste.
With ever increasing pressure to improve plant efficiency
and tighter regulations in environmental protection,
effective pH control is very desirable. However, implementing
a pH system is like putting a puzzle together. It will
only work when all the components are in place.
The pH puzzle includes effective pH probes, actuators,
and controllers. While various pH probes and actuators
for pH control are available, commercial adaptive pH
controllers are still in demand.
MFA pH Works
pH Controllers are able to control a
wide range of pH loops because its powerful adaptive
capability allows it to compensate for the large nonlinear
