OEM / ODM
OEM/ODM Solutions
Winpower works with oxygen equipment manufacturers on sensor selection, mechanical integration and output configuration.
Custom Sensing Solutions
Sensor selection follows the application area. PSA concentrators, ventilator and HFNC gas mixing, oxygen chambers, gas analyzers and particle counters each map to specific models, and some models share a name across two firmware variants — the ordering firmware must be specified.
Co-Development Support
Whether you are designing a 1.5 kg shoulder-bag POC, a backpack-mounted system, or a wearable oxygen patch, our engineering team can co-develop a sensor solution tailored to your size, weight, and power (SWaP) targets.
Flexible Output Interfaces
From 3 L homecare units to 10 L clinical systems, our sensor portfolio covers the full stationary range with consistent form factors. Standard output is UART; RS-485 and 4–20 mA are available when paired with an adapter board. Only OCS-3F2.1 and OCS-3FRL2.0 provide a direct 0–2.5V analog output.
