Industrial Process Controllers & Monitors

alpha-DO2000 Wall Mount Dissolved Oxygen Analyzer/Controller

  • Employs the Galvanic Measurement Principle

  • Programmable for On/Off, Proportional, or PI (Proportional integral CONTROL) - ideal for most demanding precision process control applications

  • Calibration is quick and easy using the atmospheric air as the calibration media for 100% air saturation

  • User-Customization through Advanced Setup Menu offers flexibility in matching the controller's functions to suit individual's specific requirement

  • Includes Barometer pressure, Salinity, Temperature Compensation

  • 0 to 2000 Second Time Delay Adjustment on control and alarm delays

  • Non-Volatile Memory retains all stored parameters and calibration data even if power fails

  • Backlit 14 segments display with symbols for status information and On/Off selectable with four levels of brightness control

  • Adjustable Hysteresis (Dead Band) prevents rapid contact switching near set point

  • Two Level Password Protection prevents unauthorized tampering with settings

  • Wash Contact Relay controls electrodes cleaning systems at desired duration and frequency

  • Universal Power Supply Input from 85 to 250 VAC/DC allows use at multiple sites and withstands voltage fluctuations

  • Choice of Temperature Sensor Pt100/Pt1000 with 2-wire or 3-wire temperature input selection

  • Dual Display shows Dissolved Oxygen value with temperature simultaneously - features clear multiple icons, set points, and status messages

  • Rugged NEMA 4X housing protects controller from the elements and dirty industrial applications

  • Easy Installation and Wiring with detachable plug-in connectors

Applications

General: Useful for monitoring temperature and control of DO in wastewater treatment and aquaculture applications. Use with valves, blowers or aerators to ensure proper system operation.
