Alvim AS11S3 Biofilm Sensor
Hygienic clamp-connection biofilm sensor with flat process-facing surface, suited to applications where hygiene is critical.
Alvim AS11S3 Biofilm Sensor
The Alvim AS11S3 is a hygienic biofilm sensor with a tri-clamp connection (DIN 32676/ISO 2852) and a flat process-facing surface offering high resistance to chemical treatments. It provides real-time detection of bacterial fouling in hygienically sensitive processes such as food and beverage production. It is well suited to plants where a clamp fitting is preferred over a threaded connection.
Description
The Alvim AS11S3 is a hygienic biofilm sensor with a tri-clamp connection (DIN 32676/ISO 2852) and a flat, stainless steel process-facing surface offering high resistance to chemical treatments. It provides real-time detection of bacterial fouling in hygienically sensitive processes such as food and beverage production, and is well suited to plants where a clamp fitting is preferred over a threaded connection.
The 1″-1½” tri-clamp connection allows quick installation and removal for cleaning. Materials in contact with the process include stainless steel (working electrode and fitting), coated titanium (counter electrode) and PEEK. It operates from -10 to +150°C, supporting CIP sanitization cycles, with conductivity greater than 10 µS/cm and pressure determined by the clamp rating. Power is supplied at 12/24V DC ±20%, 500 mA, with data output via 4-20 mA and RS485/MODBUS RTU.
It is suited to food production, mineral water bottling, soft drinks and other hygienic process applications.
Why Use This
Easy Clamp Installation
The tri-clamp fitting (DIN 32676/ISO 2852) allows quick installation and removal for cleaning, without the need for threaded connections.
Hygienic Flat Surface
A flush stainless steel surface resists chemical treatments and avoids crevices that could harbor bacteria.
Real-Time Fouling Detection
Detects the first bacterial layer in hygienically sensitive processes, reporting continuously via 4-20 mA and RS485/MODBUS RTU.
Applications
- Food production — hygienic biofilm monitoring with a clamp-style fitting
- Mineral water bottling — bacterial fouling detection in bottling lines
- Soft drinks production — real-time biofilm detection in hygienic process applications
- Plants preferring clamp over threaded fittings — quick-install tri-clamp connection simplifies maintenance
FAQ
What type of connection does the AS11S3 use?
It uses a 1″-1½” tri-clamp connection (DIN 32676/ISO 2852), allowing quick installation and removal for cleaning.
How does the AS11S3 differ from the AS01S3?
The AS11S3 uses a tri-clamp fitting rather than the VARIVENT® Type N connection, for plants that prefer a clamp fitting over a threaded connection.
What temperature range does it support?
It operates from -10 to +150°C, supporting CIP sanitization cycles.
What materials contact the process fluid?
Stainless steel (working electrode and fitting), coated titanium (counter electrode) and PEEK.
