Detect biofilm before it becomes a problem

The ALVIM Biofilm Sensor delivers the early detection that operators and quality managers need. By continuously measuring electrochemical changes within fluid-handling systems, the sensor signals when a biofilm begins to develop, allowing you to catch bacterial settlement from its very first phases.

Smarter biofilm control in your facility

When it comes to managing fluid-handling systems, relying on reactive measures leaves your process vulnerable to contamination. These patented in-line sensors provide a proactive alternative by sending a 4–20 mA or Modbus signal directly to your monitoring system in real time. This allows facilities to take corrective action at the exact right time, which reduces chemical overuse, optimizes cleaning schedules, and completely protects process integrity.

Note: The sensor is primarily for water-use applications (plant water lines, CIP lines, for example) due to its requiring stable minimum conductivity and oxygen levels for it to operate properly; the sensor is not used in direct contact with milk/product.

Reliability and precision for food manufacturers

If your food manufacturing facility requires process confidence in tough industrial environments, the ALVIM Biofilm Sensor delivers exceptional reliability and precision.

Sensitivity: Unmatched accuracy capable of detecting the very first bacterial layer.
Operating Temperature: Built to withstand -10°C to 150°C (with active biofilm monitoring between 2°C to 40°C).
Durable Construction: Wetted materials include 316Lss (fitting and working electrode), Coated Titanium (counter electrode), and PEEK.
Data Communication: Configurable for 4-20 mA or RS485/MODBUS RTU data transmission.
System Requirements: Requires >1 ppm oxygen levels and >10 µS/cm conductivity levels for optimal monitoring.
