Overview
The Sartorius Combics Intrinsically Safe Platform Scale is an engineered weighing solution designed explicitly for operation in hazardous environments governed by ATEX and IECEx directives. Built upon intrinsically safe (IS) principles, the Combics platform functions as a certified load cell-based weighing module—capable of precise mass determination without introducing ignition energy into explosive atmospheres. Its core architecture complies with Ex ia IIC T4 Ga (gas) and Ex ia IIIC T135°C Da (dust) protection levels, enabling deployment in Zone 1 (gas) and Zone 21 (dust) without additional barrier enclosures. When integrated with the CIXS3 intrinsically safe indicator—installed within the hazardous area—the system extends operational capability to Zone 20 (dust), meeting stringent requirements for continuous bulk handling in combustible dust environments. The platform’s modular topology supports seamless integration into larger process systems, including formulation, batching, filling, and transfer applications where regulatory traceability and functional safety are mandated.
Key Features
- Intrinsically safe design certified to ATEX 2014/34/EU and IEC 60079-0, -11, -26 for Zones 1, 21, and (with CIXS3) Zone 20
- 11 standardized platform dimensions supporting capacities from 0.1 g to 3,000 kg, ensuring scalability across laboratory, pilot, and industrial weighing tasks
- Modular interoperability with Sartorius hazardous-area peripherals: CIXS3 display unit, FCT01-X field controller, PR1710/6 and PR1710/7 analog transmitters, PR1711/6 digital transmitter, and PR1626/60 IS safety barriers
- Stainless steel pan and lifting hardware options—electropolished and weld-seam free—to meet hygienic process standards (EHEDG, FDA 21 CFR Part 11–compatible configurations available)
- Integrated documentation support for ATEX conformity assessment, including EC-Type Examination Certificates, Declaration of Conformity, and risk assessment templates aligned with EN 60079-32-1
- Rugged aluminum or stainless steel housing variants rated IP65/IP67, resistant to chemical exposure and mechanical impact in demanding production settings
Sample Compatibility & Compliance
The Combics platform accommodates diverse sample forms—including powders, granules, liquids in containers, and packaged goods—without compromising intrinsic safety integrity. Its load cell interface maintains metrological stability under dynamic loading conditions typical in conveyor-fed or automated dispensing systems. All components undergo rigorous electromagnetic compatibility (EMC) testing per EN 61326-1 and environmental stress screening per EN 60068-2 series. The system supports compliance workflows required under GMP Annex 11 (for electronic records), ISO/IEC 17025 (for calibration traceability), and USP / (for balance performance verification). Full audit trails, user access control, and electronic signature capabilities are enabled when paired with CIXS3 firmware v3.2+ and validated Sartorius LabX software.
Software & Data Management
Data acquisition and configuration are managed via the CIXS3 indicator’s embedded web server or through Sartorius’ LabX Balance Software—deployed on secure internal networks. LabX provides role-based user management, configurable SOP-driven workflows, automatic calibration logging, and raw data export in CSV, PDF, or XML formats compliant with ALCOA+ principles. When connected to enterprise MES or SCADA systems via Modbus TCP or Ethernet/IP, the Combics platform delivers real-time weight values with timestamped metadata, including operator ID, environmental sensor readings (optional), and certificate-of-conformance flags. All firmware updates follow IEC 62443-2-4 change control protocols, and electronic records retain immutable timestamps aligned with NIST-traceable time servers.
Applications
- Pharmaceutical ingredient dispensing in classified cleanrooms (ISO Class 5–8) where solvent vapors or API dusts pose explosion hazards
- Chemical catalyst dosing in reactor feed systems requiring Zone 1-certified weighing nodes
- Food-grade powder blending lines operating under NFPA 652-compliant dust hazard analysis (DHA)
- Explosives manufacturing facilities subject to strict DoD MIL-STD-130 and ATF 27 CFR Part 555 requirements
- Biotech fermentation media preparation using flammable solvents (e.g., ethanol, acetone) in controlled atmosphere bioreactors
FAQ
Can the Combics platform be used in Zone 20 without the CIXS3 indicator?
No. Zone 20 operation requires full system certification with the CIXS3 intrinsically safe display installed within the hazardous area. Standalone Combics platforms are certified only for Zones 1 and 21.
Is calibration traceable to national standards?
Yes. Each platform is supplied with a factory calibration certificate traceable to PTB (Physikalisch-Technische Bundesanstalt) and NIST, with optional UKAS-accredited calibration services available.
Does the system support 21 CFR Part 11 compliance?
When configured with LabX Balance Software and CIXS3 firmware v3.2+, the system supports electronic signatures, audit trails, and role-based access controls required for Part 11 adherence.
What materials are available for the load platform surface?
Standard options include anodized aluminum; stainless steel (AISI 304 or 316L) is available as an option for enhanced corrosion resistance and cleanability.
How is hazardous area documentation provided?
Sartorius supplies a complete ATEX Technical Construction File (TCF), including risk assessments, circuit diagrams, test reports, and installation instructions—formatted for submission to notified bodies during site certification audits.
