Sanitary pressure transmitters serve as critical sensors for bioprocess control in fermentation systems, primarily used for real-time pressure monitoring and regulation. These transmitters feature a fully welded 316L stainless steel construction with a surface roughness of Ra≤0.8μm, complying with 3-A Sanitary Standards and EHEDG certification to ensure reliable operation in sterile environments.
During fermentation processes, the pressure transmitter accurately measures vessel pressure (typical range: -0.1 to 0.5 MPa) with ±0.1% high precision, supporting key process controls such as:
Dissolved Oxygen (DO) Control – Optimizes aeration via precise pressure compensation.
Foam Detection – Early foam formation alerts through pressure fluctuation analysis.
Sterilization Validation – Ensures proper SIP (Steam-in-Place) conditions (e.g., 121°C/0.15 MPa for 30 min).
The specially designed diaphragm isolation system prevents media adhesion, supporting 200+ CIP (Clean-in-Place) cycles. Integrated with PROFIBUS-PA or WirelessHART protocols, pressure data is directly fed into the Bioprocess Control System (BPC), enabling closed-loop control of agitation speed and aeration. Field applications demonstrate 15% improved batch-to-batch consistency and 30% reduced contamination risk.
