Pharmaceutical Industry -- Autoclave Sterilization Control

✅ Transmitters Used:

• Gauge Pressure Transmitters: Monitor autoclave chamber pressure.
• Absolute Pressure Transmitters: Ensure accuracy in vacuum sterilization processes.

✅ Configuration:

• Material: 316L stainless steel with electropolished surfaces for hygienic applications.
• Mounting: Hygienic tri-clamp or threaded connections in sterilization chambers.
• Temperature Compensation: Up to 150°C with built-in compensation algorithms.

✅ Communication Protocols:

• HART and Foundation Fieldbus: Integrated into SCADA and DCS systems.
• Profibus PA: Supports multi-device integration in pharmaceutical plants.
• EtherNet/IP: Ensures high-speed communication for fast-response cycles.

✅ Failure Modes & Mitigation:

• Sensor Contamination: CIP (Clean-In-Place) protocols reduce sensor fouling.
• Signal Drift: Routine verification with calibrated reference standards.
• Pressure Spikes: Surge protection implemented during high-pressure autoclave cycles.

✅ Results:

• Sterilization process efficiency increased by 18%.
• Regulatory compliance with GMP and FDA standards maintained.
