Product Description

Product Description

 

The O2-C2 is a high-performance oxygen sensor developed by Alphasense Ltd., specifically designed for high-precision gas detection applications. This sensor is ideal for oxygen concentration monitoring in various industrial environments and is widely used in gas alarm systems, environmental monitoring, respiratory protection devices, and other applications requiring oxygen detection. The O2-C2 sensor employs advanced electrochemical technology to ensure long-term stability and reliability in operation.

Key Features:

• High Output Sensitivity: At 20.9% O2, the sensor output current is between 80 and 120 μA, ensuring high sensitivity and accurate oxygen detection.
• Fast Response Time: The response time from 20.9% O2 to 0% O2 is less than 15 seconds, making it suitable for gas detection systems that require quick responses.
• Excellent Zero Current Performance: The zero current in nitrogen (N2) is less than 2.5 μA, ensuring high precision and low noise operation.
• Superior Linearity: At 10% O2 concentration, the oxygen deviation is less than 0.6%, ensuring a linear relationship for precise measurements.
• Long-term Stability: The output drift after 3 months is less than 1%, and the sensor has an operating life of over 24 months in 20.9% O2, until the output drops to 85% of the original value.
• Wide Environmental Compatibility: The sensor operates in temperatures from -30°C to +55°C, making it suitable for a variety of harsh environments. The humidity range is 5% to 95% RH (non-condensing), ensuring stable performance in diverse climatic conditions.

Performance Advantages:

• Low Humidity Sensitivity: At 40°C, the humidity effect on oxygen readings is less than 0.7%, ensuring stable performance in humid environments.
• Low CO2 Sensitivity: The effect of CO2 concentration changes on the oxygen output is minimal, at just 0.1%, ensuring accurate O2 measurements even in the presence of CO2.
• Low Pressure Sensitivity: At a pressure of 20 kPa, the output change is less than 0.1%, ensuring precise measurements even in low-pressure environments.

Dimensions & Installation:

• Dimensions: The sensor has a diameter of 20.0 mm and a height of 17.4 mm, including the label and foam ring, with a weight of less than 16 grams, making it compact and easy to integrate into various devices.
• Load Resistor: A load resistor of 47 to 100 Ω is recommended for optimal performance.
• Storage Period: When stored in a sealed container at temperatures between 3°C and 20°C, the sensor can be stored for up to 6 months, ensuring long-term storage stability.

Reliability & Temperature Performance:

• Temperature Dependence: The sensor's sensitivity varies with temperature, but within a predictable range, maintaining consistency and repeatability. Temperature compensation can be applied to ensure precise oxygen measurements.
• Thermal Conductivity: After thermal shock testing from 20°C to -30°C, the sensor maintains stable performance without thermal spikes, which helps avoid false alarms.

Use and Maintenance:

• Storage & Disposal: After the sensor reaches the end of its life, do not dispose of it with regular waste. It is recommended to contact Alphasense or its authorized distributor for proper disposal instructions.
• Testing & Verification: All sensors are tested under standard environmental conditions. It is recommended that customers verify the sensor's suitability and accuracy under their specific application conditions.

The O2-C2 oxygen sensor, with its exceptional performance, stable output, and strong environmental adaptability, is an ideal choice for industrial gas detection applications. Whether in high-temperature, high-humidity, low-pressure environments, or in everyday use, it provides reliable and accurate oxygen concentration data, making it a critical component for ensuring safety.
