Supervision and control Axron CARBOBELL

Jan. 17, 2012 - PRLog -- With their intuitive graphics interface, AXRON products are easy to use. Clear functions with texts and alarms in the client’s language, facilitate familiarisation, the wide opening simplifies integration and their extensive modular system guarantees they will evolve over time.

FUNCTIONALITIES
Temperature-controlled by PID (cascade).
%C controlled with O2 probe and CO-CO2 analyzer.
On-line calculation of the part’s carbon distribution profile, effective depth and surface carbon.
Flexible programming of processing profiles with recipe library; stop-start on weekly schedule and deferred start to processing.
Management of peripherals: coolers, analyzers, quenching tank. Loading and unloading system control, automation of the quenching system, with secured manual control systems.
Calibration of the measuring instrument and sensors (AT) and calibration of the heating chamber (TUS).
Specific screens for capturing production monitoring information.
“T” models provide process value archiving (.CSV format) on detachable storage medium (USB) and on a network drive; PC software for graphic display of files generated can be supplied with the device.

SERVICES AND ADD-ONS
On-site electrical and mechanical integration.
On-site commissioning and training.
Risk analysis, compliance.
Thermal mapping (TUS), analysis of the reactor’s atmosphere.
Remote access, maintenance agreements.
Back-up and remote data archiving.
Optimisation of heat rating.
Automation of the quenching sequence.
Integration with ERP or SCADA, centralisation of recipes and/or archive data.
Installation of Remote Viewers (TCP/IP).
Can be connected to bar code readers.
