Application Fields & Cases
- Oil Refinery Catalytic Cracking Unit: A major oil refinery deployed HONEYWELL CC-TAIX51 modules in its TDC 3000 system to monitor reactor and regenerator temperatures (K-type thermocouples) in a catalytic cracking unit. The module’s cold-junction compensation ensured accurate temperature readings, while diagnostics detected a failing thermocouple before it caused process instability.
- Chemical Plant Polymerization Reactor: A petrochemical plant integrated HONEYWELL CC-TAIX51 into its TPS system to measure polymerization reactor temperatures (Pt100 RTDs). The module’s 4-wire RTD support eliminated lead wire resistance errors, delivering precise data for controlling reaction rates and preventing product degradation.
- Power Plant Boiler Temperature Monitoring: A coal-fired power plant used HONEYWELL CC-TAIX51 to monitor boiler tube metal temperatures (R-type thermocouples) in its TDC 3000 system. The module’s high-temperature accuracy and diagnostic capabilities enabled early detection of overheating, preventing tube failures and unplanned outages.

Selection Suggestions & Precautions
- Selection Suggestions: HONEYWELL CC-TAIX51 is ideal for Honeywell TDC 3000/TPS users requiring specialized temperature measurement with high accuracy (e.g., refineries, chemical plants with legacy control systems). For Emerson DeltaV users, Emerson’s Temperature AI Module is preferred; Siemens S7-400 Temperature AI Modules suit TIA ecosystem users with modern systems.
- Precautions:
- Select the correct sensor type (thermocouple/RTD) and configuration (wire count for RTD) via the engineering workstation to ensure accurate temperature conversion.
- Use shielded thermocouple/RTD extension cables to minimize EMI interference and cold-junction errors (critical for thermocouple measurements).
- Calibrate cold-junction compensation annually (per Honeywell recommendations) to maintain thermocouple accuracy, especially in extreme temperature environments.
- Ensure proper grounding of RTD sensors (3/4-wire configurations) to eliminate common-mode noise and lead wire resistance errors.
- Verify module compatibility with Experion PKS (requires adapter) if integrating into modern Honeywell systems—avoid direct installation without proper hardware.
