Alvim AX03S3 ATEX Biofilm Sensor
ATEX-certified biofilm sensor for classified explosive atmosphere zones, suited to Oil & Gas applications.
Alvim AX03S3 ATEX Biofilm Sensor
The Alvim AX03S3 is an ATEX-certified biofilm sensor built for classified hazardous areas such as Oil & Gas facilities. It provides the same real-time bacterial fouling detection as Alvim's standard sensor range, housed to meet Ex II 2G Ex mb IIB T6 Gb ratings for use in explosive atmospheres.
Description
The Alvim AX03S3 is Alvim’s ATEX-certified biofilm sensor, built for use in classified areas where there is a risk of explosion, such as Oil & Gas facilities. It provides the same real-time bacterial fouling detection as Alvim’s standard sensor range, housed to meet an Ex II 2G Ex mb IIB T6 Gb rating for use in explosive atmospheres.
It connects via a 1″ BSPP thread and is constructed with titanium (working electrode), zinc (counter electrode), POM-C, and a stainless steel threaded connector. Sensitivity covers 1-100% of surface covered by biofilm, detecting the first bacterial layer. Operating temperature is -10 to +50°C, at pressures below 10 bar, with conductivity greater than 10 µS/cm and oxygen levels above 1 ppm at maximum sensitivity. Power supply is 12/24V DC ±20%, 500 mA, with 4-20 mA and RS485/MODBUS RTU data communication.
It is suited to Oil & Gas water treatment and other classified hazardous-area applications requiring biofilm monitoring.
Why Use This
Certified for Hazardous Areas
The Ex II 2G Ex mb IIB T6 Gb ATEX rating allows safe deployment in classified Oil & Gas and other explosive-atmosphere zones.
Same Reliable Detection
Delivers the same real-time biofilm fouling detection as Alvim’s standard sensor range, so hazardous-area sites don’t sacrifice monitoring capability.
Applications
- Oil & Gas water treatment — biofilm monitoring in classified hazardous-area process water systems
- Classified hazardous zones — ATEX-rated housing (Ex II 2G Ex mb IIB T6 Gb) for use where explosive atmospheres are a risk
- Industrial process water monitoring — same 1-100% biofilm sensitivity as Alvim’s standard sensor range
FAQ
What is the AX03S3’s ATEX rating?
It is rated Ex II 2G Ex mb IIB T6 Gb, certifying it for classified hazardous zones.
How does the AX03S3 differ from the standard A001S3 sensor?
It provides the same real-time bacterial fouling detection as the standard range, but in a housing rated for explosive atmospheres, and uses POM-C and stainless steel in its threaded connector construction rather than PVC.
What temperature range does the AX03S3 operate in?
It operates from -10 to +50°C, with biofilm growth monitoring effective from +2 to +40°C.
Where is the AX03S3 intended to be used?
It is suited to Oil & Gas water treatment and other classified hazardous-area applications requiring biofilm monitoring.
