dividing wall (2 x 25 l), and drainage in both compartments.

Transparent dual process tank (2 x 10 l), interconnected through

an orifice and a ball valve and an overflow in the dividing wall;

a graduate scale and a threaded drain of adjustable level with

bypass.

• Two centrifugal pumps, range: 0 – 10 l/min.

Two variable area flow meters (0.2 – 2 l/min, and 0.2 – 10 l/min)

and with a manual valve.

Line of on/off regulation valves (solenoid). Usually one is

normally opened, and the other two are normally closed, and

manual drainage valves of the upper tank.

• Pneumatic control valve:

Pneumatic valve with positioner regulator.

• Body in stainless steel connection G 1/2”, orifice 6 mm.

The I/P converter transforms the electric signal sent from the

computer into a proportional pressure that acts over the valve.

• Helix stirrer, max. speed: 330 rpm.
• Each required element will be supplied and installed in the Base Unit: ATENG 12662

Unit for ATENG 12662, “UCPCN-UB”, and ready for working.

• The complete unit includes as well:

Advanced Real-Time SCADA and PID Control.

Open Control + Multicontrol + Real-Time Control.

Specialized Control Software based on LabVIEW.

National Instruments Data Acquisition board (250 KS/s, kilo samples per second).

Calibration exercises, which are included, teach the user how to calibrate a sensor and the

importance of checking the accuracy of the sensors before taking measurements.

Projector and/or electronic whiteboard compatibility allows the unit to be explained and

demonstrated to an entire class at one time.

Capable of doing applied research, real industrial simulation, training courses, etc.

Remote operation and control by the user, as well as remote support from technical

support, are always included.

Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).

Designed and manufactured under several quality standards.

Optional ICAI software to create, edit and carry out practical exercises, tests, exams

calculations, etc. Apart from monitoring user's knowledge and progress reached.

This unit has been designed for future expansion and integration. A common expansion is

the Scada-Net (ESN) System which enables multiple students to simultaneously

operate many units in a network.

Complete Technical Specifications (for main items)

• UCPCN/CIB. Control Interface Box:

The Control Interface Box is part of the SCADA system.

Control interface box with process diagram in the front panel and with the same distribution that

the different elements located in the unit, for an easy understanding by the student.

• All sensors, with their respective signals, are properly manipulated from -10V. to +10V. computer output.

Sensors connectors in the interface have different pines numbers (from 2 to 16), to avoid

connection errors.

Single cable between the control interface box and computer.

The unit control elements are permanently computer controlled, without necessity of

changes or connections during the whole process test procedure.

Simultaneous visualization in the computer of all parameters involved in the process.

Calibration of all sensors involved in the process.

Real time curves representation about system responses.

Storage of all the process data and results in a file.

Graphic representation, in real time, of all the process/system responses.

All the actuators’ values can be changed at any time from the keyboard allowing the

analysis about curves and responses of the whole process.

All the actuators and sensors values and their responses are displayed on only one screen in the

computer.

Shield and filtered signals to avoid external interferences.

Real time PID control with flexibility of modifications from the computer keyboard of

the PID parameters, at any moment during the process. UCPCN/CIB

Real time PID and on/off control for pumps, compressors, heating elements, control valves, etc.

Real time PID control for parameters involved in the process simultaneously.

Proportional control, integral control and derivative control, based on the real PID mathematical

formula, by changing the values, at any time, of the three control constants (proportional, integral

and derivative constants).

Open control allowing modifications, at any moment and in real time, of parameters involved in the

process simultaneously.

Possibility of automatization of the actuators involved in the process.
