Dissolved oxygen sensors and controllers for aeration and treatment processes
Online dissolved oxygen monitoring helps operators understand oxygen conditions continuously instead of relying only on manual sampling. It is commonly used where aeration, biological treatment or water-quality conditions need to be observed and adjusted over time.
Typical Applications
Wastewater aeration, biological treatment, environmental water monitoring and industrial process-water projects.
Selection Information
Provide the expected measuring range, water conditions, installation depth or method, temperature, cable length and maintenance requirements.
Control-System Integration
The controller output and alarm requirements should be confirmed according to the plant control system. Tenber can review the project conditions before recommending a controller and sensor combination.
Review industrial applications, learn about technical service, or send your process conditions for model selection.
Complete Measuring System
Match the controller, sensor and installation
Reliable online measurement depends on the complete configuration, not only the controller model.
Controller & Sensor Pairing
Choose the controller together with a membrane or optical dissolved-oxygen sensor according to response, maintenance, installation depth, cable length and water conditions.
Recommended Project Fit
Best suited to aeration basins, biological wastewater treatment, environmental water and projects that need continuous oxygen monitoring.
See application solutions or send your process conditions for a controller and sensor recommendation.
Selection Guide
Information needed for an accurate recommendation
A controller should be selected together with the sensor, installation and signal requirements. Send the following information so the configuration can be reviewed before quotation.
- Measurement parameter and required range
- Liquid type and chemical composition
- Process temperature and pressure
- Sensor installation and cable length
- 4–20mA, relay or RS485 requirements
- Expected purchase quantity
Frequently Asked Questions
Can the controller connect to a PLC?
Selected models provide 4–20mA and RS485 Modbus RTU outputs. Confirm the exact interface when requesting a quotation.
Can Tenber recommend a matching sensor?
Yes. Send the liquid, range, temperature, pressure and installation method so the controller and sensor can be selected together.
Do you support batch and OEM supply?
Tenber supports distributor and project enquiries. OEM details are confirmed according to the model and order quantity.
