Ultrasonic Oxygen Sensor for PSA Oxygen Concentrator Application PSA oxygen concentrator general introduction PSA Oxygen concentrator has been widely used in personal and medical treatment for oxygen supply. It adopts PSA technology to separate the O2 and N2 in air for continuous O2 supply. During the oxygen supply, PSA oxygen concentrator needs oxygen sensor to detect the concentration and flow range. Ultrasonic oxygen sensor has been widely used in PSA oxygen concentrator to measure the oxygen concentration and flow. Normally, the purity of oxygen concentrator is less than 95%, because during the air separation, there is also gas like Ar, CO2 apart from O2 and N2. It is different from oxygen cylinder and has no 100% pure oxygen environment. Oxygen concentration measurement in oxygen concentrator 1. Collect the air from outdoor 2. Filter screen and air compressor 3. Molecular sieves separate the O2 and N2. 4. Gasboard7500E detects O2 Concentration and send digital reading of O2 concentration. Why we should use ultrasonic oxygen sensor Ultrasonic oxygen sensor Gasboard7500E uses the ultrasonic velocity difference between upstream and downstream to detect the gas flow and also the oxygen purity for oxygen concentrator. It is generally used for testing the oxygen concentration of binary mixture such as A (oxygen) In A+B ( A and B have different density and different travel speed). A is oxygen, and B is usually N2 or air.
