Description

YOKOGAWA ZR22G-100-S-C-E-T-Q-E-A Split-type Zirconia Oxygen Analyzer Detector

Product Dimensions：

The Yokogawa ZR22G-100-S-C-E-T-Q-E-A is a separate-type Zirconia Oxygen Analyzer probe. It is part of the ADMAG ZR series, renowned for its durability and precision in monitoring oxygen concentration in combustion flue gases.

Below is a detailed breakdown of this specific model.

1. Product Description

The ZR22G is a general-purpose probe that uses a Zirconia sensor to measure oxygen concentration. It is designed to be inserted directly into a flue or furnace. This “separate-type” system means the probe is installed at the measurement point and connected via a cable to a remote converter (usually the ZR402G).

2. Product Parameters (Based on Model Code)

The suffix code -100-S-C-E-T-Q-E-A defines the specific configuration:

Technical Specifications:

• Measurement Range: 0.01% to 100% $O_2$

• Process Temperature: Up to 700°C (standard)

• Sample Gas Pressure: -5 to +5 kPa

• Repeatability: $\pm 0.5\%$ of maximum scale

• Response Time: 90% response within 5 seconds

3. Product Advantages

• In-situ Measurement: Eliminates the need for complex sampling systems, reducing maintenance and lag time.

• Field-Replaceable Sensor: The Zirconia cell can be replaced easily on-site without disposing of the entire probe.

• High Accuracy: Features a high-stability heater control to ensure precise readings even during process temperature fluctuations.

• Long Life: The heater and sensor assembly are built to withstand harsh, corrosive combustion environments.

4. Product Applications

This probe is primarily used for combustion control and environmental monitoring in:

• Power Plants: Optimizing fuel-to-air ratios in large boilers.

• Refineries: Monitoring process heaters and crackers.

• Iron & Steel: Reheating furnaces and soaking pits.

• Incinerators: Ensuring complete combustion and emission compliance.

5. Important Notes & Precautions

• Thermal Shock: Avoid rapid cooling of the sensor. Do not use water or wet air to clean a hot probe.

• Mounting Orientation: Ideally installed horizontally or vertically downward. Avoid upward installation where condensate can collect on the sensor.

• Calibration: Periodic calibration with “Standard Gas” is required to maintain accuracy. Ensure the calibration gas lines are leak-free.

• Safety: The probe operates at high temperatures (the internal heater reaches roughly 750°C). Use caution during handling and maintenance.
