Winpower OCS-3F_3.0 Ultrasonic Oxygen Sensor

The OCS-3F_3.0 employs ultrasonic technology to provide accurate and stable measurements of oxygen concentration ranging from 21% to 95.6%, with a resolution of 0.1% and an accuracy of ±1.5% FS within a temperature range of 5 to 55°C. It also measures flow rates between 0 to 10 L/min, offering a resolution of 0.1 L/min and an accuracy of ±0.2 L/min or 5% of the reading, whichever is greater, at 25°C. The sensor features a UART digital output compatible with 5V TTL or 3.3V CMOS levels, and provides LED indicators to display oxygen concentration levels: green for concentrations above 82%, yellow for concentrations between 50% and 82%, and red for concentrations below 50%. Operating on a DC 6.5-12V power supply with a typical current consumption of 50mA, the sensor is factory-calibrated, ensuring long-term stability and a lifespan of up to 5 years.
