Alvim AS01S3 Biofilm Sensor
Hygienic biofilm sensor with VARIVENT connection and flat process-facing surface, suited to applications where hygiene is critical.
Alvim AS01S3 Biofilm Sensor
The Alvim AS01S3 is a hygienic biofilm sensor featuring a VARIVENT Type N connection and a flat process-facing surface for high resistance to chemical cleaning treatments. It delivers real-time detection of bacterial fouling in applications where hygiene standards are critical, such as food and beverage production. The sensor outputs data via 4-20 mA and RS485/MODBUS RTU for integration with plant monitoring systems.
Description
The Alvim AS01S3 is a hygienic biofilm sensor featuring a VARIVENT® Type N connection and a flat, stainless steel process-facing surface designed for high resistance to chemical cleaning treatments. It delivers real-time detection of bacterial fouling in applications where hygiene standards are critical, such as food and beverage production.
The VARIVENT® Type N connection fits pipes from DN 40 to DN 150. Materials in contact with the process include stainless steel (working electrode and connector), coated titanium (counter electrode), PEEK and an EPDM O-ring. The sensor operates from -10 to +150°C, supporting CIP sanitization cycles, at pressures below 10 bar and conductivity greater than 30 µS/cm. It is powered at 12/24V DC ±20%, 500 mA, and outputs data 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
Hygienic by Design
The flat, VARIVENT-connected stainless steel surface resists chemical treatments and avoids crevices where bacteria could otherwise collect.
CIP-Compatible
Rated to +150°C, the sensor withstands clean-in-place and sanitization cycles common in food and beverage production.
Real-Time Monitoring
Detects the first bacterial layer and reports continuously via 4-20 mA and RS485/MODBUS RTU for integration with plant control systems.
Applications
- Food production — hygienic biofilm monitoring in process lines
- Mineral water bottling — bacterial fouling detection in bottling process water
- Soft drinks production — real-time biofilm detection in hygienic process applications
- Other hygienic process applications — suited to plants using VARIVENT-standard fittings on DN 40 to DN 150 pipes
