Production Description:
RDO-200 Fluorescence Dissolved Oxygen Sensor
Application
Widely used in online dissolved oxygen monitoring for power plant, chemical, industrial wastewater, pharmaceutical, biochemical and water treatment industry.
Feature
0-20mg/L or 0-200% saturation
0 ~ 50 ; IP68 protection rating
No film, no electrolyte, not polarization
No consumption of oxygen, the flow rate is not affected
Built-in temperature sensor, automatic temperature compensation
Chemical interference from sulfide
In drift, fast response, more accurate measurements
Maintenance-free longer applicable period, lower cost
Fluorescent cap replacement is simple
Supports RS-485, MODBUS protocol
Measuring principle:
luminescent dissolved oxygen sensor is based on a specific matter physics quench the fluorescence of the active principle. From a light-emitting diode Blue light (LED) in the fluorescence emitted by the phosphor surface of the cap, the inner surface of the fluorescent substance is excited, emit red light, by detecting the phase difference between the red and blue, and with internal calibration values and compared to calculate the concentration of molecular oxygen, temperature and pressure through the automatic compensation output a final value.
