YOKOGAWA ZR22G-150-C-C-E-T-T-E-AF1SCTC analyzer specifications. In-situ zirconia oxygen probe, 1500mm insertion, HART, ATEX, high temperature.

Product Overview

The YOKOGAWA ZR22G-150-C-C-E-T-T-E-AF1SCTC is an in-situ zirconia oxygen analyzer probe designed for continuous measurement of oxygen concentration in high-temperature combustion gases. This model features a 1500mm (1.5 meter) extended insertion length, specialized flange connection, HART communication, and ATEX hazardous area certification. The AF1SCTC suffix defines specific advanced options including calibration unit configuration, special materials, and customized certifications for extreme process conditions.

Technical Specifications

Key Features

• Ultra-Long 1500mm Probe Length:​ Designed for very large ducts, deep insertion requirements, and special process penetrations

• Specialized Flange Connection:​ Custom flange configuration for non-standard or high-temperature applications

• Dual HART & Analog Output:​ 4-20mA analog signal with superimposed HART digital communication

• ATEX/IECEx Certified:​ Certified for hazardous area installation (Zone 1/2, 21/22)

• Enhanced Corrosion Resistance:​ Titanium/Ta construction for aggressive flue gas environments

• Advanced Calibration System:​ AF1SCTC suffix specifies integrated automatic calibration with solenoid valve manifold

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

• **​ Comprehensive Diagnostics:​ Real-time monitoring of cell impedance, heater status, sensor drift, and calibration validity

Applications

• Very large utility boilers (ultra-supercritical coal, combined cycle gas turbines)

• Extreme temperature industrial furnaces and process heaters

• Large cement and lime rotary kilns requiring deep insertion

• Glass melting furnaces

• Metallurgical processes (steel reheat furnaces)

• Hazardous area installations requiring full ATEX/IECEx compliance

• Flue gas desulfurization (FGD) upstream/downstream monitoring

Important Notes

1. The 150​ suffix designates 1500mm insertion length; C-C​ indicates special flange and calibration port configuration; E-T-T-E​ defines HART output, titanium construction, ATEX certification, and enhanced electronics; AF1SCTC​ denotes advanced flow system with 1-set calibration gas unit and special traceable certification.

2. This is a complete high-spec probe assembly​ requiring a compatible ZR402G or ZR202S converter/transmitter.

3. The AF1SCTC calibration system​ includes pre-configured solenoid valves, flowmeters, and gas regulators for fully automatic zero/span calibration sequences.

4. Special flange material and facing​ are matched to extreme process temperatures and pressures; verify compatibility.

5. Probe support brackets and guide rails​ are strongly recommended for 1500mm insertion length to prevent mechanical stress.

6. For SIL applications, verify safety manual and functional safety assessment availability.

7. Installation must ensure​ adequate clearance for probe retraction and maintenance.
