Catalog excerpts

An oxygen sensor is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. Oxygen sensors are used in oxygen analyzers which find a lot of use in medical applications such as anesthesia monitors, respirators and oxygen concentrators. Ultrasonic oxygen sensor uses the ultrasonic velocity difference between upstream and downstream to detect the gas flow and also the oxygen purity for oxygen concentrator. And the biggest advantage of ultrasonic technology is no need of routine calibration and long life span. Principle of ultrasonic technology Ultrasonic flow detection theory: When the ultrasonic wave transmits in the fluid, it will carry flow velocity under the influence of fluid velocity. Fluid velocity can be measured by detecting the received ultrasonic signal to obtain the fluid flow rate. The feature of ultrasonic flow measurement is no obstructing fluid flow, etc. Ultrasonic concentration detection theory: when the binary gas mixture composition has molecular weight difference, sound travel speed varies from different gas composition. Main applications • PSA oxygen concentrator • Anesthesia machine • Medical ventilator • Oxygen analyzers Main features • Cutting-edge ultrasonic technology adopted • Small size, stable, high accuracy, low cost • No need of routine calibration • Long life span (>5 years) • Customized available
