NS-DO106 Fluorescence Dissolved Oxygen Sensor Introduction: The fluorescence dissolved oxygen digital sensor NS-DO106 integrated online fluorescence dissolved oxygen sensor is designed and manufactured based on the quenching principle of excitation fluorescence by specific substances in physics. The blue light emitted by light emitting diodes (LEDs) shines on the fluorescent substance on the inner surface of the fluorescent cap, which is excited and emits red light. By detecting the phase difference between red and blue light and comparing it with the internal calibration value, the concentration of oxygen molecules is calculated, and the final value is automatically compensated by temperature. Features: 1. No electrolyte required, no polarization 2. No oxygen consumption required, unaffected by flow rate 3. Built in temperature sensor, automatic temperature compensation 4. Not affected by chemical substances such as sulfides 5. Small drift, fast response, and more accurate measurement 6. Maintenance free, long service life, and lower usage cost 7. Easy replacement of fluorescent caps 8. RS-485 interface, Modbus RTU protocol Technical parameters: Model: NS-DO106 Measurement principle: fluorescence method Range range: 0-20.00mg/L (0-200% saturation, 25 ℃) Resolution: 0.01mg/L, 0.1 ℃ Accuracy: ± 2% F.S. ± 0.5 ℃ Temperature compensation: Automatic temperature compensation (Pt1000) Output method: RS-485 (Modbus/RTU) Working conditions: 0-45 ℃,<0.2MPa Storage temperature: -5~65 ℃ Installation method: immersion installation Cable length: 5 meters, other lengths can be customized Power consumption: 0.1W@12V Power supply: 12-24VDC Protection level: IP68 Calibration: Two point calibration Fluorescent cap lifespan: Guaranteed for one year of use (under normal use) Sensor housing material: POM and 316L stainless steel
