Data acquisition systems form the basis for transparent, documented, and standards-compliant monitoring of thermal processes. In industrial heat treatment, they are used to reliably record and archive measured values such as temperature profiles, hold times, and atmospheric conditions. In combination with Demig process controllers and the Prosys process control system, an integrated solution is created for seamless in-process control and digital production documentation.
The Role of Data Acquisition in Heat Treatment
Processes such as hardening, annealing, or brazing are subject to strict requirements regarding compliance with tolerances and industry-specific standards (e.g., CQI-9, AMS 2750). Demig’s data acquisition systems enable complete and automated traceability of all process steps—from the start of the batch to the final inspection. This ensures compliance with both internal quality standards and external audit requirements.
Demig combines traditional data acquisition with modern automation technology:
- Real-time acquisition of measured values directly from the process controllers
- Centralized visualization and storage in the prosys/2 process control system
- Batch-specific data archiving for traceability and reporting
Integration with process controllers and the control system
The performance of a data acquisition system depends largely on the depth of its integration. With the controller families DE-CP 3XX and DE-CP 5XX controller families, as well as the prosys/2 SCADA system, Demig offers a perfectly coordinated comprehensive solution:
- Direct connection of controllers via Ethernet or serial interfaces
- Automatic assignment of process data to job and batch information
- Long-term archiving with backup management and data export functionality
Thanks to its modular architecture, the solution can be scaled to any plant size and industry requirement—whether a single furnace or a fully networked production line.
Added value for production, quality, and compliance
Data acquisition is far more than just a documentation tool—it is increasingly becoming a decisive factor for cost-effective and safe production. With Demig systems, users benefit from:
- Reduced susceptibility to errors and greater process reliability
- Clear chain of evidence for quality inspections and customer requirements
- Greater transparency and predictability through systematic data analysis
In addition, Demig’s systems support all common industry standards and are thus future-proof for audits and certifications.
Conclusion
Data acquisition systems ensure safety, transparency, and compliance with standards in industrial heat treatment. In combination with high-performance process controllers and the prosys/2 process control system, Demig offers a highly integrated, scalable, and audit-ready solution for seamless in-process control—a decisive advantage for manufacturing companies on their path to digitalized production.
