Envitec Oxygen Sensor OOA101

The Envitec Oxygen Sensor OOA101, developed by Honeywell, is engineered for precise oxygen measurement in automotive applications. Below are its key specifications:

• Measurement Range: 0% to 100% oxygen at atmospheric pressure.

• Output in Ambient Air: 7 mV to 13 mV.

• Electrical Interface: 3-pin Molex® connector (Molex® 22-04-1031).

• Accuracy:

  • 0% to 3.3% oxygen: ±0.1% absolute.
  • 3.4% to 100% oxygen: ±3% relative.

• Linearity Error: Less than 3% relative.

• Response Time:

  • Less than 5 seconds to 90% of final value.
  • Less than 40 seconds fall time from 20.95% to 0.1% oxygen when 100% nitrogen is applied.

• Zero Offset Voltage: Less than 40 µV in 100% nitrogen.

• Cross Interference: Less than 0.1% oxygen response to 15% CO₂, 10% CO, 3000 ppm NO, 3000 ppm C₃H₈, 500 ppm H₂S, 500 ppm SO₂, and 1000 ppm benzene in nitrogen.

• Influence of Humidity: -0.03% relative per % RH at 25°C.

• Pressure Range: 0.6 bar to 2 bar (ppO₂ 0 to 1250 mbar O₂).

• Influence of Pressure: Proportional to change in oxygen partial pressure.

• Influence of Mechanical Shock: Less than 1% relative after a fall from 1 meter.

• Operating Temperature: 0°C to +50°C.

• Temperature Compensation: Built-in NTC compensation.

• Effect of Temperature Compensation (steady state):

  • Between +25°C and +40°C: 3% relative error.
  • Between 0°C and +50°C: 8% relative error.

• Nominal Sensor Lifetime: Greater than or equal to 500,000% volume oxygen hours.

• Recommended Load: Greater than or equal to 10 kΩ.

• Warm-Up Time: Less than 30 minutes after sensor replacement.

• Weight: Approximately 28 grams.

This sensor is PTB-A 18.10 approved and meets BAR 97 requirements, ensuring compliance with stringent automotive standards.
