Winpower manufactures ultrasonic and limiting current oxygen sensors for medical, industrial, and automotive applications. The portfolio covers seven application areas: PSA oxygen concentrators (stationary and portable), ventilators and HFNC high-flow therapy, oxygen chambers, gas analyzers (handheld and module), and particle counters.
Every sensor is manufactured by Winpower Technology Co., Ltd. in Shenzhen, China. Measurement ranges, output interfaces, and operating conditions differ between models — each product page lists its own specifications and datasheet.
Browse our oxygen sensor portfolioAn oxygen sensor measures the concentration of oxygen (O₂) in a gas mixture, or the partial pressure of oxygen in a process stream. Two sensing technologies are used across medical and industrial equipment: ultrasonic and limiting current (zirconia).
Ultrasonic sensors derive the oxygen concentration from the speed of sound travelling through the gas mixture, because sound velocity depends on gas composition. There is no consumable sensing element and no chemical reaction involved.
Limiting current sensors use a zirconia solid-electrolyte cell held at high temperature. Oxygen pumped through a diffusion barrier produces a current that saturates at the limiting value, which is approximately linear with the oxygen concentration of the measured gas.
Winpower manufactures both ultrasonic and limiting current oxygen sensors, covering medical, industrial, and laboratory applications.
The portfolio spans compact in-line sensors for concentrators and ventilators, handheld analyzers, and industrial-grade sensing modules.
OEM and ODM engineering support is available for firmware, connector, cable, housing, and logo customization.
Winpower operates under ISO 9001 and IATF 16949 quality management systems.
