Product Description:
YJJ DM-OFC-B0 Ultrasonic Oxygen Concentration & Flow Sensor O2 Purity Module for PSA Oxygen Concentrator
Features:
Basic Information
- Model: DM-OFC-B0
- Detection principle: Ultrasonic flight time TOF, using the time difference of the forward and reverse flow of ultrasonic waves to simultaneously measure oxygen concentration and flow rate
- Measuring medium: Binary mixture of oxygen and nitrogen (output gas from a molecular sieve oxygen generator)
- Application: Integrated into **medical oxygen generators and industrial oxygen equipment**, for real-time online monitoring of oxygen purity and output flow rate; equipment comes with a replacement sensing module
- Core advantages: No consumable components, no issue of electrolyte depletion in electrochemical oxygen sensors, long-term stability, no need for frequent calibration
Core measurement parameters
- O₂ concentration range: **20.5% ~ 95.6% VOL**
- Concentration resolution: 0.1% VOL
- Concentration accuracy: ±1.5% FS (5~45℃)
- Flow rate range: **0 ~ 10 L/min**
- Flow rate resolution: 0.1 L/min
- Flow rate accuracy: ±0.2 L/min
- Response time T90: ≤ 1s
- Preheating: Ready to work upon power-on, reaches full precision indicators within 3-5 minutes
Electrical parameters
- Supply voltage: DC 5V ~ 12V (typical DC 12V)
- Average working current: ≤ 40mA
- Communication output: UART TTL 3.3V (9600 baud rate), can be selected with analog voltage output as needed
- Built-in: **Temperature compensation algorithm**, reduces environmental temperature drift
Environmental conditions
- Working temperature: 5℃ ~ 50℃
- Working humidity: 5~85% RH, **no condensation**
- Maximum tolerance pressure: 150kPa
- Sample gas requirements: Gas needs pre-filtering, no condensate water, no large amount of dust
- Service life: ≥ 10 years
Physical specifications
- Dimensions: 120.5 × 22 × 22 mm
- Weight: 25g
- Gas path: No direction restrictions for inlet and outlet gas, direct-through gas path, minimal pressure loss
Product selling points (for self-built stations)
1. Ultrasonic TOF technology, simultaneously collecting two parameters of oxygen concentration and flow rate, single module replaces 2 sensors
2. No consumable materials, long lifespan, no drift over long-term use, reduces maintenance and calibration costs
3. Built-in temperature compensation, stable and reliable measurement under oxygen generator conditions
4. UART digital serial port output, convenient for integration into embedded motherboards, compatible with medical / industrial PSA oxygen generation equipment
5. Direct-through gas path, low pressure loss, easy installation, suitable for ODM of complete machines and maintenance replacement
