Why CIP Cannot Clean Threaded Pressure Taps
Pressure transmitter solutions for demanding industrial applications. The DR3413 series delivers reliable performance.
The Problem: Hidden Bacteria in Dead-Legs
A batch failed quality control after swab tests revealed bacteria post-CIP. The culprit? Pressure taps created dead-legs where product residue accumulated, evading cleaning cycles. Over time, this compromised hygiene standards.
The Solution: Flush Diaphragm Design
We replaced traditional threaded taps with the DR3413, a sanitary pressure transmitter featuring a flush diaphragm. This design eliminates dead-legs entirely, ensuring complete cleanability and reducing bacterial growth risk. The flush diaphragm allows the sensor face to be flush with the pipe wall, preventing residue traps.
Key Specifications
- Hygienic, flush diaphragm design
- Supports CIP (Clean-in-Place) and SIP (Sterilize-in-Place)
- Stainless steel wetted parts
- High accuracy for critical processes
- Food-grade compliant design (3A)
Why It Works: Physics of Cleanability
Dead-legs create stagnant zones where flow velocity drops below the threshold needed to remove biofilms. The DR3413’s flush diaphragm eliminates these zones, allowing turbulent flow to sweep the sensor face clean. This ensures CIP chemicals reach all surfaces, reducing bacterial survival.
The Result: Verified Cleanliness
Post-CIP swab tests now show zero bacterial growth. The 3A certified design gives confidence in compliance with dairy and food standards.
Reflect on Your Process
When was the last time you swabbed a pressure tap post-CIP to verify cleanliness? If you’re relying on traditional taps, you might be at risk. Learn more about the DR3413 hygienic pressure sensor and how it can improve your hygiene protocols.
