RP-A01Ultrasonic Oxygen Sensor
Gas Analyzer
Ultrasonic oxygen analyzer module with dual measurement modes for fixed PSA concentrators and portable pulse-dose concentrators.
Product Introduction
RP-A01 portable oxygen generator detector is developed by Winpower Technology Co., Ltd. on the basis of the company's ultrasonic oxygen sensor. It uses the ultrasonic principle to detect the oxygen concentration in the gas, uses the high-precision flow meter to detect the single discharge volume and continuous flow rate of the portable oxygen generator, and uses the high-precision pressure sensor to detect the pressure of the oxygen outlet. This applies to portable oxygen generators and conventional oxygen generators.
Features
- Ultrasonic oxygen detection — measures oxygen concentration using ultrasonic principle with ±1.5% accuracy
- High-precision flow meter — detects single discharge volume and continuous flow rate up to 50 slm
- High-precision pressure sensor — detects oxygen outlet pressure up to 180 kPa with ±0.3 kPa accuracy
- Dual detection modes — pulse detection mode and normal detection mode for versatile measurement
- RS485 & USB communication — supports serial data transmission at 115200 bps via Type-C or RS485 port
- Rechargeable lithium battery — 900mAh battery with 8–10 hours cruising ability and 2.5–3 hour charge time
Applications
Precautions for Use
- This product is only used to detect the output gas of PSA oxygen generator and must not be used for life support systems.
- 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.
- Handle gently to avoid collision with other objects so as not to affect the detection accuracy of the instrument.
- If the instrument fails, do not disassemble or repair without permission; contact the manufacturer in time.
