The GUNT Multivariable Control System for Vacuum Degassing enables practical learning of complex control engineering concepts using a real-world process engineering model. The system simulates degassing of dissolved gas in a vacuum tank and highlights the dynamic interaction between level and pressure control loops.
Product Features
- The experimental unit enables hands-on learning of complex multivariable control systems.
- Uses a process model based on vacuum degassing—a common application in process engineering.
- Gas (ambient air) is separated from liquid (water) in a vacuum tank via desorption.
- Water jet pump creates negative pressure in the vacuum tank to initiate gas separation.
- Negative pressure draws water from the collecting tank into the vacuum tank and mixes it with ambient air.
- Water/air mixing ratio is controlled via rotameters and valves.
- Degassed water is pumped from the vacuum tank back to the collecting tank.
- A control valve adjusts flow rate, influencing the water level in the vacuum tank.
- Separate circuit with pump and control valve controls flow to the water jet pump, adjusting the vacuum pressure.
- Negative pressure and water level are interdependent, forming a complex multivariable control scenario.
- Two industrial-grade digital controllers manage pressure and level loops independently.
- Controllers can be configured and parameterised using included software.
- PROFIBUS DP interface allows monitoring via optional RT 650.60 software.
- RT 650.60 enables PC-based process variable recording and controller configuration.
- Multiple trainers in the GUNT series can be interconnected through the PROFIBUS interface.
