The Industrial Processes Control Workstation, "AE-PLC-CPI", designed by EDIBON, is a unit that integrates different technologies to implement four closed-loop control loops: flow, level, temperature, and pressure. The different control loops are quickly and easily configured using a flexible system of ball valves and pipe connections.
The workstation features different types of digital and analog sensors and actuators to implement four closed-loop control loops: flow, level, pressure, and temperature.
PID control is performed through a proportional valve, which responds to variations indicated by the analog sensors corresponding to each control loop. Additionally, there are elements to generate disturbances in the system and observe the resulting response to the control.
It consists of three integrated circuits or stations:
- Cold water circuit.
- Hot water circuit.
- Water accumulator circuit.
The main components are:
- Workstation: composed of real industrial components, implemented to implement different PID controls, using analog and digital sensors, manual valves, solenoid valves, proportional valves, heat exchangers, radiators, and fans, etc.
- Pneumatic system: composed of a pneumatic ball actuator and an air filtration system.
- Control panel: with a Start/Stop button, emergency stop button, and indicator light to display the system status.
- Cold water circuit: composed of a proportional valve, flow meter, pressure sensor, pressure switch, plate heat exchanger, radiator, and fan. The pump circulates the water throughout the entire circuit. It has thermocouples to monitor the temperature.
- Hot water circuit: composed of thermocouples, a pump, and a plate heat exchanger. It is an independent circuit that transmits energy through the heat exchanger to the cold water circuit.
- Accumulator circuit: This circuit is derived from the cold water circuit and has a pneumatic ball actuator for draining. A solenoid valve directs the water pumped by the cold water circuit into the accumulator.
