RP-A02Ultrasonic Oxygen Sensor
Gas Analyzer
Ultrasonic oxygen analyzer module dedicated to pulse-mode testing of portable pulse-dose oxygen concentrators.
Product Introduction
RP-A02 pulse oxygen detector is developed by Winpower Technology Co., Ltd. on the basis of our ultrasonic oxygen sensor. In pulse measurement mode, it measures the single supply volume of the oxygen generator, and records the trigger times, the number of misjudgments, the trigger pressure, the maximum instantaneous flow rate, the volume of 1 minute, the temperature and the oxygen concentration. In direct supply oxygen detection mode, the flow rate of oxygen, air and air oxygen mixture can be measured, and the gas temperature and oxygen concentration of the gas can be detected. This product is suitable for portable oxygen generators and conventional oxygen generators.
Features
- Pulse measurement mode — measures single supply volume with trigger count and misjudgment tracking
- Direct supply detection mode — measures flow rate of oxygen, air, and air-oxygen mixtures
- Adjustable trigger frequency — supports respiratory rates of 10, 15, 20, 25, 30, 35, 40
- Adjustable trigger pressure — settable pressures of 30, 35, 40, 45, 50, 55, 60
- RS485 communication — serial data transmission at 115200 bps with relay support for up to 16 machines
- Built-in air pump — creates negative pressure process to trigger the oxygen generator automatically
Applications
Precautions for Use
- This product can detect the output gas of the PSA oxygen generator, pure oxygen, and pure oxygen mixed with air.
- This product is applicable within an atmospheric pressure range of 50 kPa to 150 kPa, corresponding to an altitude range of below 5500 meters.
- When in use, please empty the humidification bottle of the oxygen generator, or directly remove the humidification bottle, to avoid water entering the detector and damaging the instrument.
- Dust filtration is required and please stay away from fire during operation.
- If the instrument fails, do not disassemble or repair without permission; contact the manufacturer in time.
