Application Scenarios
2) Product features
- Optical, maintenance?free digital DO sensor with special long-life light source; fast and precise readings.
- Measurement ranges: DO 0–20.00 mg/L (0–200.00%), temperature ?10.0–100.0 °C; accuracy ±1% FS for DO, ±0.5 °C for temperature.
- Communications: RS485 Modbus RTU. Outputs: two isolated 4–20 mA channels (DO and temperature).
- Built?in datalogging and history-curve review; three relays (two for high/low alarms, one for cleaning control).
- Protection rating IP65; compact dimensions (144 × 144 × 104 mm, panel cutout 138 × 138 mm).
3) Product value
- Enables reliable, continuous online monitoring of oxygen levels to protect processes and ensure water quality (including seawater supply).
- Reduces operating costs via maintenance?free optical sensing and long sensor lifetime.
- Facilitates process control and remote integration with 4–20 mA and Modbus outputs plus alarm relays.
- Historical data logging supports troubleshooting, compliance reporting and trend analysis.
4) Product advantages
- Optical sensing avoids frequent membrane/electrolyte maintenance required by electrochemical probes, improving uptime.
- High precision and fast response suitable for demanding and harsh environments (saltwater, industrial effluent).
- Flexible integration options (isolated analog outputs + RS485) and alarm/control relays for automated systems.
- Robust IP65 housing and multiple mounting options for easy installation and protection in field conditions.
5) Application scenarios
- Sea water supply monitoring and seawater treatment systems.
- Industrial wastewater and effluent monitoring and control.
- Drinking water systems and environmental water quality monitoring.
- Process control in pulp & paper, chemical industry, aquaculture and other water/wastewater treatment applications.
