PresSure Products Company’s PPC-CMS Concentration Monitoring
System provides continuous monitoring and accurately controls the
concentration of aqueous-based cleaning agents in your inline cleaner.
Concentration imbalances can occur through assembly-related dragover,
evaporation, or bath level adjustments. The PPC-CMS not only gives precise
control of the process to resolve this problem, it also greatly reduces
chemistry usage. The system’s unique design ensures that concentration is
controlled at a point just before the spray nozzles—where it counts.
How the PPC-CMS Works
The PPC-CMS is easily and unobtrusively
fitted to most inline cleaners. It includes a state-of-the-art
refractometer,which is used to measure the refractive
index of the chemistry and automatically adjust the amount of chemistry
in the wash tank to maintain the proper concentration. The refractometer
sensor is fitted to a sampling loop, through which a sample of
the wash solution flows. This approach permits precise control of the
chemistry, making the system robust and nearly maintenance-free.
A programmable logic controller
(PLC) monitors the wash solution concentration, injection
of chemistry,duration of injection, and all status
alarms. Depending upon the severity of the alarm, the
PLC may shut down the system. Both pre-set and actual
concentration values are displayed for the operator
using the BRIX scale. |
