Pyxis ST-772 Luminescent Dissolved Oxygen Sensor

Model:
ST-772
Brand:
Pyxis

The Pyxis ST-772 uses luminescent (optical) dissolved oxygen detection, avoiding the membrane replacement and electrolyte refill required by older galvanic and polarographic DO sensors. This standard-body variant is suited to process and wastewater dissolved oxygen monitoring. Isolated 4-20mA analog and RS-485 Modbus outputs support direct integration with a PLC, SCADA, or third-party controller.

Description

The Pyxis ST-772 uses luminescent (optical) dissolved oxygen detection, avoiding the membrane replacement and electrolyte refill required by older galvanic and polarographic DO sensors. This standard-body variant is suited to process and wastewater dissolved oxygen monitoring.

Because it relies on optical rather than chemical detection, the sensor removes a recurring maintenance task from DO monitoring programmes, letting operators focus on readings rather than consumable replacement.

Isolated 4-20mA analog and RS-485 Modbus outputs support direct integration with a PLC, SCADA, or third-party controller.

Why Use This

Lower maintenance dissolved oxygen monitoring

Luminescent optical detection eliminates the membrane replacement and electrolyte refill needed by older galvanic and polarographic DO sensors.

Straightforward controller integration

Isolated 4-20mA analog and RS-485 Modbus outputs connect directly to a PLC, SCADA, or third-party controller.

Applications

  • Process water dissolved oxygen monitoring — continuous optical DO tracking
  • Wastewater treatment monitoring — DO measurement without membrane or electrolyte maintenance

FAQ

How does this DO sensor differ from a galvanic or polarographic sensor?

It uses luminescent (optical) dissolved oxygen detection, avoiding the membrane replacement and electrolyte refill required by older galvanic and polarographic DO sensors.

What applications is it suited to?

Process and wastewater dissolved oxygen monitoring, in a standard sensor body configuration.

How does it integrate with a control system?

Via isolated 4-20mA analog and RS-485 Modbus outputs, for direct integration with a PLC, SCADA, or third-party controller.
