Power/RS 485 Comm. Ultrapure Water

Transcription

1 Rouge Monitor A complete Rouge Monitoring System consists of three pieces: Stainless Steel Probe that is inserted into the ultrapure process stream Local E 9020 Rouge Detection Transmitter Remote display control, data logging and retransmission unit Power/RS 485 Comm Analog Output of Rouge Rate and Rouge Thickness to Customer DCS System Data-logger upload to PC Downtime costs reduced by planned re-passivation schedules Alarm Abnormal water quality and process changes Instantaneous Rouge Rate in microns/month Accumulated Rouge in microns The Rouge Monitor was developed specifically for stainless steel ultrapure water systems. The patented Solution Resistance Compensation (SRC) incorporated in our electrochemical measurement technology enables very low corrosion (rouging) rates to be measured accurately in the high resistivity of ultrapure water. The Rouge Monitor has a high sensitivity front end probe/transmitter and a remote display, data logger, and analog retransmission unit. The remote display unit provides analog 4-20 ma outputs of rouging rate in microns/month and accumulated rouging in microns for connection to a DCS or SCADA system. In addition, the on-board data logger enables independent data accumulation for direct transfer to a laptop, which is convenient for your water treatment service provider. The display unit provides power and RS 485 digital communication to the sensing probe and transmitter, enabling the display unit to be mounted up to 4000 feet from the probe/transmitter. The resistivity of ultrapure water is 18.2 Megohms at 25C. Normal rouging rates are in the range of 0 to microns per month. The Rouge Monitor accurately measures the rouging rate in the range of 0 to microns per month, and will display rouging rate excursions up to microns/month.
