Product Overview

The YOKOGAWA ZR22G-150-C-C-E-T-T-E-AF1SCTC-01 is an in-situ zirconia oxygen analyzer probe designed for continuous oxygen measurement in extreme high-temperature combustion processes. This model features a 1500mm (1.5 meter) extended insertion length, custom flange connection, HART communication, and ATEX hazardous area certification. The AF1SCTC-01 suffix specifies advanced calibration system hardware with traceable certification and enhanced documentation package for critical applications.

Applications

• Ultra-large utility boilers (coal, oil, gas-fired)

• Combined cycle gas turbine (CCGT) HRSG systems

• Very large cement and lime rotary kilns

• Glass melting furnaces with deep port requirements

• Metallurgical reheat furnaces and soaking pits

• Hazardous area installations requiring full ATEX/IECEx compliance

• Critical process applications requiring enhanced calibration traceability

Important Notes

1. Model Interpretation:​

   • 150​ = 1500mm insertion length

   • C-C​ = Special flange + calibration gas port

   • E​ = HART output

   • T-T​ = Titanium construction + ATEX certification

   • E​ = Enhanced electronics

   • AF1SCTC-01​ = Advanced flow system, 1-set calibration unit, special traceable certification

2. Requires a compatible converter​ (ZR402G, ZR202S) for signal processing and power supply.

3. AF1SCTC-01 calibration assembly​ includes solenoid valve unit, flowmeters, pressure regulators, and factory test report with traceability.

4. 1500mm insertion requires​ mechanical support brackets and guide rails to prevent vibration and stress.

5. Special flange rating​ must be verified against maximum process temperature and pressure.

6. Installation must follow​ YOKOGAWA guidelines for minimum straight duct length and safe probe retraction.

7. The zirconia cell is fragile​ — handle with extreme care during installation, operation, and maintenance.
