Test Stand for Level Pressure Control- Engineering Lab Training Systems

Technical Description  This high quality test stand enables to perform complex experiments on a multivariable system often used in practice. In this particular case, a vacuum degassing model is used as an example of an interacting two-variable control system. Vacuum and level are the two variables to be controlled in a process tank. Pressure and level are interdependent variables.  The system has a closed water circuit. The vacuum is generated by a waterjet pump with its own water circuit. Two pneumatic control valves control vacuum generation and discharge from the tank. The test stand contains high quality instrumentation. The controllers have a Profibus DP interface. This interface allows the test stand to be monitored by optional process control software . This software can also be used to record process variables and to tune controller parameters via PC.
