Key Features
- High Operational Safety: The transmitter continuously validates sensor and process data, with user-customizable alarms and calibration integrity checks. This reduces measurement errors in critical applications like wastewater treatment.
- Flexible Communication: Integrated HART and Profibus protocols enable seamless integration into control systems. Optional relays support advanced functions such as limit alarms or timer controls for automated processes.
- Simple Maintenance: A dedicated calibration button and guided menu streamline sensor calibration in air, oxygen-saturated water, or process media. The plug-in design allows rapid module replacement without rewiring.
- Rugged Design: The IP65-rated housing protects against dust and water ingress, ensuring reliability in outdoor or humid environments. The compact form factor simplifies mounting in space-constrained panels.
- Sensor Compatibility: Optimized for use with Endress+Hauser's COS41/COS61 optical or amperometric DO sensors, ensuring accurate data across varying temperatures and media conditions.
Application Scenarios
- Wastewater Aeration Control: Monitors dissolved oxygen in activated sludge tanks to optimize blower efficiency and reduce energy consumption in municipal plants.
- Drinking Water Monitoring: Ensures oxygen levels remain within safe limits for public water supplies, with compliance reporting via digital interfaces.
- Aquaculture Management: Maintains optimal oxygen concentrations in fish farms to support aquatic health and growth, using reliable probes resistant to biofouling.
- Surface Water Analysis: Deployed in rivers or lakes for environmental monitoring, with robust construction enduring long-term exposure to elements.
