The Computer Controlled Process Control (Electronic Valve), "UCP", designed by EDIBON, allows the study of several types of automatic control and can be used to control different variables (flow, level, temperature, pressure, pH, conductivity and TDS) in several ways.
The control is done automatically by acting on an electronic valve.
The minimum supply consists of two main elements: the Base Unit for UCP, "UCP-UB", and at least one of the required elements described below.
The main elements of the Base Unit for UCP, "UCP-UB", are:
- Storage tank and collector at the top of the unit with hole in the central dividing wall and drainage in both compartments (methacrylate).
- Dual process tank, interconnected through an orifice and a ball valve and overflow in the dividing wall, preventing the complete flooding of the tank and allowing to modify its effective liquid volume.
- Hydraulic circuit composed by two centrifugal circulation pumps, two flow meters, three all/nothing solenoid valves and a motorized proportional valve (infinitely variable) for control.
- Helix stirrer, which guarantees a good uniformity of the variables to be controlled.
Required elements (at least one) (Not included):
- UCP-T. Set for Temperature Process Control for UCP.
- UCP-C. Set for Flow Process Control for UCP.
- UCP-N. Set for Level Process Control for UCP.
- UCP-PA. Set for Water Pressure Process Control for UCP.
- UCP-PH. Set for pH Process Control for UCP.
- UCP-CT. Set for Conductivity and TDS (Total dissolved Solids) for UCP.
All these required elements, designed by EDIBON, allow the user to perform different types of controls, and to study experimentally the different responses of the system. It will be possible to perform closed loop control by means of an all or nothing controller (ON/OFF), learn how to reach a desired value manually, perform control by means of a proportional controller (P), perform control by means of a proportional + Integral controller (PI), perform control by means of a proportional + Derivative controller (PD), study experimentally the characteristics of the integral, proportional or derivative component of a PID controller, adjust the components of a PID controller for the control of different variables, etc.
In addition, all our units are supplied with a process diagram explaining the location of all elements, valves, sensors, actuators, etc. found in the unit.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
