Product Details
O2S-FR-T2-18C O2S-FR-T2 Zirconia Oxygen Sensor Are For Combustion
Control Environmental Monitoring
Product Overview:
O2S-FR-T2 is a high-precision, long-life oxygen sensor using
zirconia (ZrO₂) technology, suitable for industrial process
control, combustion monitoring, environmental monitoring, and other
fields. It determines the oxygen concentration in the environment
by measuring oxygen partial pressure, featuring rapid response and
strong anti-interference capability.
Product Features:
- High Precision and Stability
- Adopts non-consumable zirconia sensing elements, requiring no
frequent calibration and ensuring long-term stability.
- No cross-interference with other gases (such as CO, CO₂, H₂, etc.).
- Rapid Response
- Built-in heating elements ensure the sensor reaches operating
temperature quickly, reducing warm-up time.
- Dynamic measurement technology adapts to rapidly changing oxygen
concentration environments.
- Wide Temperature Operation
- Can directly measure high-temperature gases (e.g., boiler exhaust)
without additional cooling.
- Digital Communication
- Supports Modbus RTU protocol for easy integration into industrial
control systems or PLCs.
- Parameters (e.g., measurement range, alarm thresholds) can be
configured via software.
- Low Maintenance Cost
- No need for regular replacement of electrolytes or consumables;
only periodic probe cleaning is required.
Application Fields:
- Combustion Control: Air-fuel ratio optimization for boilers,
furnaces, kilns, etc., to improve energy efficiency.
- Environmental Monitoring: Exhaust gas emission monitoring and flue
gas analysis.
- Industrial Processes: Inert gas protection (e.g., electronics
manufacturing, food packaging), fermentation process monitoring.
- Medical Equipment: Oxygen concentration monitoring in oxygen
generators, anesthesia machines, etc.
- Scientific Research: Oxygen control in enclosed environments (e.g.,
incubators, glove boxes).
