A SCADA/HMI control system, originally intended only for vacuum brazing furnaces, has found much broader application. Developed by Specnow of Huntingdon, the company quickly realised that it could also control furnaces used in many sectors and that it was suitable for equipment such as electron beam welding systems Specnow has built a pair of identical, vacuum furnaces for an aerospace client, one of which will be installed in the UK, the other being destined for a sister plant in Mexico. They are used for brazing stainless steel assemblies that form the main bodies of linear sensors, used in aircraft for monitoring undercarriages. Knowing that the user operates to NADCAP (the National Aerospace and Defence Contractors Accreditation Program) standards, Specnow has used Movicon, a high functioning, but cost effective, SCADA/HMI control system.
