Yokogawa DO30G Sensor for Dissolved Oxygen Analyzer General Specifications

General Specifications DO30G Sensor for Dissolved Oxygen Analyzer GS 12J05D03-01E n GENERAL The DO30G sensor for dissolved oxygen is designed for use in water treatment plants such as sewage treatment works, effluent activated sludge process, and potable water treatment. It is also effective in river monitoring, intake protection, fish farming and other fields where water quality is important. This galvanic cell has a fast response time and good long term stability, and features replaceable diaphragm and cable for easy maintenance. A temperature sensor is incorporated for compensation. The DO30G sensor can be used in either the PB350G/PB360G floating ball holders or in the DOX8HS submersion type holder. DO30G Sensor n FEATURES DO Sensor with Long-term Stability and Short Electrolyte Stabilization Time • A DO sensor that uses a special electrolyte, shortening the electrolyte stabilization time and realizing stable measurements over a long period of time. • Measuring range of 0 to 20 mg/L • A membrane that is easily replaceable by anyone because of the cartridge type • A membrane 50 mm thick that is hard to tear and has reduced influence from air bubbles PB350G Floating ball holder n SYSTEM Refer to GS 12J5D2-E for dissolved oxygen converter DO402G, GS 12J05C01-01E for 2-wire transmitter DO202, GS 12A01A03-01EN for 2-wire liquid analyzer FLXA202, GS 12A01A02-01E for 2-wire liquid analyzer FLXA21 and GS 12J05C02-00E for holders DO Sensor • DO30G Select pin terminal of DO30G sensor for DO402G, DO202. Accessories • DOX8A Holder, Holder with Cleaner • Guide pipe PH8HG DO Converter • Floating ball holder PB350G PB360G • DO402G, DO202 or FLXA202/FLXA21 Jet cleaner • WTB10-DO3, -DO4 • Submersion type holder DOX8HS Without cleaner Terminal Box • Suspension holder HH350G Note: “DO” of DO sensor means dissolved oxygen. CAUTION Installation Location of Holders (Guide Pipe, Submersion Type, etc) The holder should be used in a place that is as vibration free as possible. Using the holder in a place where it is affected by vibration, may result in damage to the holder.
