Galvanic oxygen sensors play a vital role within diving ensuring the safety and well-being of divers in critical underwater environments. These sensors are essential components of diving equipment, where stability, accuracy, and reliability are very important.
To avoid serious risks to health, the levels of moisture, oxygen and CO in scuba tanks need reliable and accurate control. The safety and quality of the breathing air or specialist gas mixtures used by industrial or leisure divers is essential. The analyzers and sensors are designed to meet the demands of rebreather and scuba diving equipment and tested to the most exacting standards in the industry.
Diving O2 sensors are crucial components of diving rebreathers, sophisticated devices that allow divers to breathe underwater by recycling exhaled air. These sensors monitor the oxygen concentration within the rebreather, ensuring that divers receive the correct amount of oxygen.
Given the extreme pressures and challenging conditions underwater, the stability, accuracy, and reliability of these sensors are non-negotiable. A malfunctioning sensor could render a $7,000 rebreather useless, jeopardizing the diver's life. This critical need for dependable performance is why there is a high demand for expedited shipping options for these sensors, ensuring that divers receive timely replacements or spares for their planned trips.
How do they work?
At the heart of the galvanic fuel cell sensor is a simple yet innovative mechanism. When oxygen from the sample gas comes into contact with the sensor, it diffuses through a front-sensing membrane. This membrane is crucial because it selectively allows oxygen to pass through while blocking other gases and impurities, ensuring an accurate measurement.
The Electrochemical Process
Once the oxygen molecules penetrate the membrane, they reach the cathode, a vital component of the sensor. Here, a reduction reaction occurs, where oxygen molecules gain electrons. These electrons are provided by the simultaneous oxidation of the anode, another essential part of the sensor's design.
The fascinating part of this process is the flow of electrons from the anode to the cathode. This movement of electrons generates a current, which can be measured externally. What makes the galvanic fuel cell sensor particularly valuable is that this current is both proportional and linear to the partial pressure of oxygen (PO2) in the sample gas. In other words, the higher the concentration of oxygen, the greater the current produced.
Measuring Oxygen Levels
The generated current, measured in microamperes (μA), provides a direct indication of the oxygen levels in the sample gas. This linear relationship simplifies the interpretation of results, making it easy to determine the exact partial pressure of oxygen present.
