Function
The four controlled systems can be operated individually. The level and flow control system can be configured as cascade control with a corresponding controller (FluidLab-PA multi-loop required). The design of the sensors and actuators allows both continuous (e.g. P, I, PI, PID) and discontinuous controller types (e.g. 2-point controller). The pump can be directly controlled or speed-controlled
.
In the flow and pressure control sections, the control variable of the controller can also be used to control a proportional directional control valve. A 2-way ball valve with pneumatic rotary actuator is installed in the return flow between the elevated tank and the lower storage tank. This simulates a "consumer" in order to switch on a disturbance variable in the level control system.
The workstation has IO-Link components (level, temperature and magnetic flow sensors) for digital communication between devices.
The MPS PA Compact Workstation Basic contains the mechanical and electrical components, sensors and drives that together form the process line.
The MPS PA Compact Workstation Process Instrumentation is equipped with parameterizable sensors that can be used to familiarize yourself with the functions of typical control devices and the HART communication protocol down to the smallest detail.
The MPS PA Compact Workstation Energy is equipped with current and power meters to analyze energy consumption and efficiency.
Each MPS PA Compact Workstation learning system contains the following control unit variant:
