Working Principle

The YMJN-O-11 measures oxygen concentration in a gas sample using its oxygen sensing system and digital processing electronics. The sensor responds to oxygen in the sample, and the instrument processes the resulting signal to calculate and display oxygen concentration.

The analyzer can transmit measurement data through its analog current output or a selectable RS232/RS485 interface. Configured upper- and lower-limit alarm outputs can be used to notify operators when oxygen concentration exceeds predefined thresholds.

The specific sensing technology is not provided in the supplied specifications. Sensor compatibility, sample conditioning requirements, and suitability for particular exhaust gas compositions should therefore be confirmed with the manufacturer.

Frequently Asked Questions (FAQ)

1. What is the YMJN-O-11 High Standard Exhaust Gas Oxygen Analyzer used for?

It is designed to measure oxygen concentration in industrial gas streams and laboratory samples, supporting combustion optimization, process monitoring, and gas analysis.

2. What is the oxygen measurement range?

The standard specified range is 0–100% oxygen. Alternative measurement ranges can be selected according to the application.

3. How accurate is the YMJN-O-11?

The specified accuracy is ≤ ±1% of full scale (FS). For a 0–100% FS range, this corresponds to ±1 percentage point of oxygen concentration.

4. How quickly does the analyzer respond?

The specified T90 response time is 15 seconds or less.

5. Does the analyzer support analog and digital outputs?

Yes. It supports a selectable 0–20 mA or 4–20 mA current output and an RS232 or RS485 communication interface.

6. Can the YMJN-O-11 be used for combustion control?

Yes. It is suitable for oxygen monitoring in combustion-related processes at thermal power plants, cement plants, and metallurgical facilities, provided the sample conditions meet the instrument requirements.

7. What are the installation requirements?

Install the analyzer horizontally in an environment with a temperature of 5–45°C and relative humidity of 0–85%. Avoid direct sunlight, vibration, shock, and strongly corrosive gases.

8. Does the analyzer have alarm functions?

Yes. It supports upper- and lower-limit passive relay outputs. Audible, visual, display, and message-based alerts depend on the supplied configuration.

9. Can it measure oxygen in any exhaust gas?

Not necessarily. Gas composition, corrosive components, moisture, pressure, temperature, and sample conditioning can affect sensor performance. Confirm compatibility with the manufacturer before measuring a specific exhaust gas.
