YOKOGAWA ZR22G-100-S-A-E-T-M-E-ACVCS2 analyzer specifications. In-situ zirconia oxygen probe, 1000mm insertion, HART output, ATEX certified.

Product Overview

The YOKOGAWA ZR22G-100-S-A-E-T-M-E-ACVCS2 is an in-situ zirconia oxygen analyzer probe designed for continuous measurement of oxygen concentration in high-temperature combustion gases. This model features a 1000mm (1 meter) insertion length, standard flange connection, analog output, HART communication, and ATEX hazardous area certification. The extended suffix "ACVCS2" defines specific options including calibration gas unit, materials, and approvals for demanding industrial applications.

Technical Specifications

Key Features

• Extended 1000mm Probe Length:​ Designed for large ducts and deep insertion requirements

• In-situ Direct Measurement:​ Eliminates extractive sampling systems, provides real-time O₂ data

• HART Communication:​ Remote configuration, diagnostics, and digital process variable access

• ATEX/IECEx Certified:​ Suitable for installation in potentially explosive atmospheres (Zone 1/2, 21/22)

• Integrated Calibration Gas Port:​ Enables automatic or manual on-site calibration

• High-Temperature Capability:​ Direct exposure to flue gases up to 700°C

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

• Advanced Diagnostics:​ Continuous monitoring of cell impedance, heater status, and calibration validity

• Corrosion-Resistant Construction:​ Suitable for aggressive flue gas environments

Applications

• Large utility boilers (coal, gas, oil-fired)

• Industrial furnaces and process heaters

• Cement and lime kilns (deep insertion required)

• Waste-to-energy and incineration plants

• Petrochemical and refinery fired heaters

• Hazardous area installations requiring ATEX/IECEx approval

Important Notes

1. The model code defines a complete, pre-configured assembly: ZR22G​ (probe), 100​ (1000mm length), S​ (standard flange), A​ (analog output), E​ (HART), T​ (standard titanium construction), M​ (ATEX/IECEx certified), E​ (enhanced options), ACVCS2​ (specific calibration certificate and option package).

2. A compatible converter/transmitter (e.g., ZR402G, ZR202S) is required for signal processing and loop power.

3. Automatic calibration requires external solenoid valve unit, zero/span gas cylinders, and regulators (sold separately).

4. Installation must follow YOKOGAWA guidelines for minimum straight duct length and proper probe support.

5. The zirconia cell is fragile; probe must be handled carefully, especially during insertion and removal.

6. For ATEX applications, ensure local wiring practices and cable entries meet Ex e or Ex d requirements per installation manual.
