Oxygen sensor

High‑Precision Zirconia Oxygen Sensor – Ultra‑Fast Response & Wide Temperature Range

The sensor employs a platinum‑thin film over a zirconia electrolyte, providing a proportional voltage output that accurately reflects atmospheric oxygen concentration. Its built‑in hot‑film heating element maintains a stable temperature above 800 °C, ensuring linear behavior and reliable measurement over the entire measurement range. Designed for automotive, industrial, and laboratory applications, this sensor delivers exceptional stability, low drift, and compliance with rigorous automotive emission standards.

• Key Spec 1: Output – 0.5 V to 1.0 V (0–21 % oxygen), 4 V low‑power digital interface available
• Key Spec 2: Operating Temperature – –40 °C to +125 °C, −55 °C to +175 °C for high‑performance models
• Key Spec 3: Response Time – 5 ms start‑up, <30 ms for 10–90% rise, <10 ms for 90–10% fall
• Common Use Case: Catalyst monitoring and air‑fuel ratio control in automotive engine management systems
