Ultrasonic oxygen concentration sensor is developed for oxygen concentration level test and O2 flow rate monitor. Based our strong power in ultrasonic technology,our oxygen concentration sensor has been widely used for PSA type oxygen generator in home,hospital,military marine,etc.
PSA O2 generator can make oxygen by molecular sieve,and this method is physical process. Unlike chemistry method, it doesn't produce pollution or bad material.Thus, PSA oxygen technology has been widely used for oxygen generators. In the past, oxygen cell was used to monitor O2 concentration,but the oxygen cell belongs to chemistry method and have many disadvantages.Thus, ultrasonic O2 sensor has been an ideal solution.
Oxygen concentration is a very key factor for oxygen breathing and oxygen therapy. If oxygen concentration is not well adjusted, it won't bring healthy,instead, it will cause harmful to people body. Thus, a hard rule has been done to add oxygen level monitor to oxygen generator machine. In the past, oxygen cell was used to monitor oxygen concentration,but oxygen cell is a kind of consuming method.Its life would become short as its using and meanwhile,its accuracy may be degraded.
Thus, we decide to develop oxygen concentration sensor on advanced ultrasonic testing technology. Ultrasonic type has a longer life and better performance. Except O2 concentration, ultrasonic O2 sensor can also measure flow,temperature,pressure by different sensor models.
- Home and Hospital PSA type oxygen making machine,e.g. Oxygen concentrator, Portable oxygen generator
- Existing type oxygen machine without concentration monitor function
- Gas analyzer
- Concentration checking of mixed air
Ultrasonic Oxygen Concentration Sensor
The oxygen sensor is only used to test oxygen concentration and has a smaller body and lower price. Comparing with other type, this one has a small size and lower cost. If you don't require flow function and accept serial port TTL output, this is your better choice.

- Connect port: 2.54mm 4P
The oxygen sensor can be communicated by TTL serial port and for related communication protocol,please feel free to contact us.
Ultrasonic Oxygen Flow/Concentration Sensor
UOCF-200 can measure oxygen flow and concentration together.In order to get stable flow,its size is a little bigger than UOC-202. If select digital display module,it also has a LED output function which can indicate O2 concentration range by different color LED light.
The O2 sensors can support different styles of LCD or LED indication module. We can also support customization service for different display design.

Portable Oxygen Concentration Meter
Based on our ultrasonic oxygen concentration sensor, we can develop portable oxygen concentration meter which can be used to test O2 concentration,flow and pressure for PSA type O2 generator and oxygen concentrator. The portable O2 meter has been widely in home and medical. It is powered by battery and an ideal measurement tool to check and monitor oxygen flow/concentration rate at real-time.
- Concentration range:73%-96.0%
- Flow range:0.0-10.0L/min
- Pressure range: 0-100Kpa
- Net weight: 300g
- Oxygen measurement condition: O2/N2 binary,other should be less than 1%
Value-added to Your Oxygen Generator/Oxygen Concentrator
The ultrasonic oxygen concentration sensors can help to improve your competitiveness. You just add our ultrasonic O2 sensor to your oxygen concentrator and the adding cost is very low. The default output of the O2 sensor is TTL (UART) output,and with related communication protocol,it is easy to read real-time data of oxygen concentration,flow and temperature(decided by different models of O2 sensors).The O2 sensors have been widely used for portable and stationary type oxygen generators/O2 concentrators under PSA method.
We can also provide related controlling PCB or LCD module if you don't want to develop it. That can save you time cost and reduce your research time. If your existing oxygen machine is analog output,e.g.voltage,4-20mA,etc, we can specially make it as requirement.
With our oxygen concentration sensors, you can gain benefits as below:
- O2 concentration indication to make O2 breathing properly.
- Flow test function can reduce an variable area flow meter. This can reduce your material cost.
- Flow accuracy of O2 sensors is higher than variable area flow meter.
- Compact size design,more suitable for portable oxygen generator or reduce your machine size. After all,space in car or house is always crowded.
- Can also readout value of pressure or temperature.
- Longer using life than variable area flow meter or chemistry type O2 concentration sensors.
- Improving your product value with advance ultrasonic technology
