Fluorescent Oxygen Sensor, 0-25%/0-300mbar/500-1200mbar

Purchase industrial fluorescent oxygen sensors utilizing non-contact optical principles to effectively prevent electrochemical drift. The oxygen sensor detects oxygen concentrations from 0 to 25%, partial pressure ranges from 0 to 300 mbar, and atmospheric pressure ranges from 500 to 1200 mbar. It maintains stable operation across a wide temperature and humidity range (-30°C to 60°C, 0% to 95% RH).

Feature

• The gas sensor incorporates an integrated barometric pressure sensor, making it impervious to atmospheric pressure fluctuations. It directly outputs readings for ambient atmospheric pressure (measuring range: 500–1200 mbar), oxygen partial pressure (measuring range: 0–300 mbar), and oxygen concentration (measuring range: 0–25%), facilitating easy user interpretation.
• Compared to electrochemical sensors, this optical oxygen sensor utilizes non-depleting oxygen-sensitive materials, offering a longer service life with a design lifespan of no less than 10 years.
• The fluorescence oxygen sensor operates at 4.75–5.25V with an average current of 7.5mA, featuring low power consumption, exceptional stability, and environmental friendliness. It contains no lead or other hazardous substances.
• Due to the high selectivity of oxygen-induced luminescence quenching, cross-sensitivity with other gases is minimal, making it virtually immune to interference from other gases.

Working Principle

When the oxygen-sensitive membrane is excited by incident light, it emits light. The presence of molecular oxygen causes this emitted light to be quenched, with the quenching period being proportional to the oxygen concentration. Higher oxygen concentrations result in shorter quenching times, and vice versa, enabling the calculation of oxygen concentration. This SUCH fluorescent oxygen sensor offers excellent stability and extremely fast response speed.
