SC5200 STREAMING CURRENT DETECTOR The Milton Roy Model SC5200 Streaming Current Detector <SCD> is an on line electrokinetic charge analyzer thai mea- sures the net kmk and partide surface charge in a chemically treated water or wastewater sample. The SCD allow* con- tinuous monitoring and control of the coagulation process, thereby providing; * Consistent water quality * Uniform chemical dosing under varying conditions * Reduced chemical costs * Automatic operation of the treatment process The SC520O is a complete SCD and process controller in one package Once installed, it is ready to control any coagulant dosing pump or control valve that accepts a 4*20 mA process signal. No other control instruments are required for a dosed loop control. The SC5200 represents the most advanced level of Streaming Current Technology available today. The SC520Cs electron- ics, sampling system and overall design are the direct result of years of studies and research and development aimed at advancing the technology. Though SOD'S have been an ac- cepted pan of water treatment for over a decade, the SC5200 incorporates a number of key Improvements that provide even greater stability, response, and improved operation over previous successful designs In addition, the SC5200 is the first of a new generation of SCO's designed to operate In wastewater treatment. Special probe designs and electronic advances have opened the door to controlling coagulant feed to belt presses, centrifuges, and other dewatcring equipment. JET WA5H SAMPLE CELL CLEANING The Automatic VL Wash is an optional patented sample cell cleaning system available on Milton Roy SCO's* The system is designed to maintain cell cleanliness and signal reliability by automatically Hushing the sample cell on a predetermined cyde. Rushing is accomplished by Injecting water at high velocity through the bottom of the sampling cell, which scours the cell surfaces and force* contaminants into the sample stream drain. Cleaning frequency is field adjustable to suit the application. Signal output is automatically locked during the cleaning cycle to ensure control stability. 5C5200 MODEL SELECTION GUIDE Output Signal Probfl Cleaning Options 0 = Standard Manual Jet Wash Other Opti Operating Voltage Communications Options Automatic Jet Wash is factory set at 30 seconds every 2 hours.
