The FST 100-DO103A Dissolved Oxygen Sensor is an integrated online fluorescence dissolved oxygen sensor designed based on the quenching principle of excited fluorescence by specific substances in physics. When the excitation light shines on the fluorescent substance on the surface of the fluorescent membrane head, the fluorescent substance is excited and emits fluorescence. The extinguishing time of the fluorescence is affected by the concentration of oxygen molecules on the surface of the fluorescent membrane head.
The concentration of oxygen molecules can be calculated by detecting the phase difference between fluorescence and excitation light and comparing it with the internal calibration curve, and outputs the final value after temperature and salinity compensation.
Features :
- Fluorescence-based Detection: Uses the quenching principle of fluorescence to measure dissolved oxygen concentration.
- High Accuracy: Provides precise measurements with ±2% FS accuracy.
- Automatic Temperature Compensation: Adjusts measurements for temperature variations using a Pt1000 sensor.
- Submersible Design: Can be installed in tanks or pipes with 3/4″ NPT threads for both submersible and socket mounting.
- Low Power Consumption: Operates on 12-24V DC with only 0.2W power usage.
- Robust Construction: IP68-rated protection, making it suitable for harsh environmental conditions.
- Long Cable Length: Standard 5-meter cable, with customization options for longer lengths.
