KGZ-NGL-096-273 Zirconia Oxygen Sensor

1. Overview:

• A flange-mounted zirconia oxygen sensor from UK-based SST, designed for sampling chambers. Favored by aerospace clients and applications requiring high-temperature and high-pressure operations.

2. Operating Conditions:

• Working Voltage: 4.35VDC ± 0.1VDC (1.85A)
• Standby Voltage: 2VDC (0.85A)
• Permissible Gas Temperature: -100°C to +250°C
• Gas Flow Rate: 0–10 m/s

3. Electrical Characteristics:

• Pump Impedance at 700°C: <6 kΩ
• Output Signal: Oxygen partial pressure measurement range: 2 mbar–3 bar, accuracy: ≤5 mbar
• Calibration-free design: No reference gas required; simple single-point calibration feasible in any known gas (including fresh air).

4. Temperature Characteristics:

• Internal Operating Temperature: 700°C
• Recommended Preheating Time: 60–100 seconds before sensor operation
• Output Stability Time: Stabilizes within 180 seconds after startup

5. Mechanical Characteristics:

• Repeated Allowable Acceleration: 5g
• Incidental Allowable Acceleration: 30g
• Termination: 0.4m cable with Molex connector

6. Other Features:

• Response Time (T90): <4 seconds
• Measurement Technology: Closed-loop measurement system. The sensor generates a "heartbeat" signal during continuous O₂ level monitoring, providing immediate fault warnings.
• Service Life: Up to 10 years (application-dependent), using non-depletable sensor cell technology.
• Structure: Zirconia (ZrO₂) sensing element, full stainless steel construction, flange-mounted, pin terminal.
• Environmental Adaptability: Operable in high-temperature, humid, and pressurized environments. Its robust structure allows use in harsh conditions, with no need to replace electronics at the end of the sensor's life.

Applications:

• Aerospace oxygen monitoring
• High-temperature industrial furnaces
• Combustion efficiency optimization systems
• Pressure vessel environment detection
