YOKOGAWA ZR22G-070-S-C-E-T-T-E-A Oxygen Analyzer | In-situ, Zirconia, 700mm, HART

YOKOGAWA ZR22G-070-S-C-E-T-T-E-A analyzer specifications. In-situ zirconia oxygen probe, 700mm insertion, HART, high temperature.

Product Overview

The YOKOGAWA ZR22G-070-S-C-E-T-T-E-A is an in-situ zirconia oxygen analyzer probe designed for continuous measurement of oxygen concentration in high-temperature combustion gases. The model code defines a complete configuration including 700mm probe length, standard flange connection, internal heater, calibration gas port, and HART communication output. It is suitable for direct installation in boiler flue ducts, furnaces, and industrial kilns for combustion efficiency optimization.

Technical Specifications

Key Features

• In-situ Direct Measurement:​ Installs directly in flue gas duct; no sampling system required

• 700mm Probe Length:​ Suitable for medium to large ducts

• Internal Heater:​ Maintains zirconia cell at constant 750°C for stable measurement

• HART Communication:​ Remote configuration, calibration, and diagnostics

• Integrated Calibration Port:​ Allows automatic or manual span/zero calibration without probe removal

• High Temperature Capability:​ Process gas up to 700°C

• Robust Flanged Connection:​ Leak-tight installation with standard industrial flanges

• Self-Diagnostics:​ Continuous monitoring of cell impedance, heater, and calibration status

Applications

• Boiler flue gas oxygen measurement for combustion control

• Industrial furnace optimization (steel, glass, ceramics)

• Process heaters in refineries and petrochemical plants

• Waste incineration plants

• Kilns in cement and lime production

• Any combustion process requiring oxygen trim control

Important Notes

1. The long suffix defines a specific complete configuration: 070 = 700mm probe, S = standard flange, C = calibration gas port, E = HART output, T = titanium standard construction, etc.

2. A separate converter/transmitter unit (e.g., ZR402G, ZR202S) is required to process the probe signal and provide the 4-20mA output.

3. For automatic calibration, additional hardware (solenoid valves, regulators) and calibration gases are required.

4. Probe must be installed at a representative location with adequate straight duct length and minimum insertion depth as per manual.

5. The zirconia cell is fragile; handle with care during installation and maintenance.
