Electric parts

PLC-Control systems

According to your requirements, we provide extensive control systems based for centrifuge operation on our standards:
  • Programmable logic controler
  • Components, e.g. Siemens Simatic S7, Rockwell
  • Automatic and manual program sequence
  • Modular composition -> Upgrade can be easily realized
  • Optimized programming of application specific software

Local operator panel

  • Components certified according to ATEX (Ex II 2G Ex e q [ib] IIC T4 )
  • Visualization of prozess on TFT-panel PC 10, 4"
  • Connection with control system via Profibus interface -> no need of inherently safe cables

Drive technology

Frequency converter for continuous control of revolution or Star/Triangle Soft Starter System

Brake resistor or power feedback unit during shutdown of centrifuge
