Based on the fluorescence quenching principle, the sensor provides accurate and stable measurements without the need for frequent maintenance.
Operating Principle:
-
Blue light emitted by an LED irradiates the fluorescent material inside a special cap.
-
The fluorescent material is excited and emits red light.
-
The phase difference between the blue and red light is compared with internal calibration values.
-
Based on this data, the concentration of oxygen molecules is calculated.
-
The value is automatically adjusted for temperature and atmospheric pressure.
