Pyxis ST-772T Luminescent Dissolved Oxygen + Temperature Sensor
Optical/luminescent dissolved oxygen sensor with integrated temperature measurement, standard body. Isolated 4-20mA + RS-485.
Pyxis ST-772T Luminescent Dissolved Oxygen + Temperature Sensor
The Pyxis ST-772T uses luminescent (optical) dissolved oxygen detection, avoiding the membrane replacement and electrolyte refill required by older galvanic and polarographic DO sensors. This variant includes an integrated temperature sensor alongside dissolved oxygen measurement in a standard body construction. Isolated 4-20mA analog and RS-485 Modbus outputs support direct integration with a PLC, SCADA, or third-party controller.
Description
The Pyxis ST-772T uses luminescent (optical) dissolved oxygen detection, avoiding the membrane replacement and electrolyte refill required by older galvanic and polarographic DO sensors. This variant includes an integrated temperature sensor alongside dissolved oxygen measurement, in a standard body construction.
Combining DO and temperature readings in a single probe simplifies installation where both parameters need tracking at the same process point, without adding a second sensor.
Isolated 4-20mA analog and RS-485 Modbus outputs support direct integration with a PLC, SCADA, or third-party controller.
Why Use This
Two measurements from one probe
Integrated temperature sensing alongside dissolved oxygen reduces the number of separate probes needed in a monitoring point.
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 DO and temperature monitoring — combined readings from a single probe
- Wastewater treatment monitoring — DO and temperature tracking without membrane or electrolyte maintenance
FAQ
Does this sensor measure temperature as well as dissolved oxygen?
Yes. The ST-772T includes an integrated temperature sensor alongside dissolved oxygen measurement, in a standard body construction.
How does the DO detection method compare to older sensors?
It uses luminescent (optical) dissolved oxygen detection, avoiding the membrane replacement and electrolyte refill required by older galvanic and polarographic DO sensors.
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.
