SPECIFICATIONS

PBCC. Unit:
Anodized aluminium structure and panels in painted steel.
Main metallic element in stainless steel.
Diagram in the front panel with similar distribution to the elements in the real unit.

Centrifugal pump, computer controlled:

  • Maximum flow: 80 l/min.
  • Maximum height (approx.): 20 mwc (meter of water column).
  • Pump-and-engine-set coupled to an AC motor.
  • Pump speed adjustable from the computer (PC).
  • Regulating valves.
  • Torque measurement and speed measurement.
  • Discharge pressure sensor (0 to 2.5 bar).
  • Admission pressure sensor (-1 to 0 bar).
  • Flow sensor (0-150 l./min).

By the previous sensors we can make the measurement of the most representative
parameters of the pump:

 

  • Speed.
  • Torque.
  • Total impelled flow.
  • The admission and discharge pressure.
  • Water transparent tank, capacity: 60 l.

 


PBCC/CIB. Control Interface Box :
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.
Simultaneously 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 placed in only one computer screen.
Shield and filtered signals to avoid external interferences.
Real time computer control with flexibility of modifications from the computer keyboard of the
parameters, at any moment during the process.
Real time computer control for pumps, compressors, resistances, control valves, etc.
Open control allowing modifications, at any time and in a real time , of parameters involved in the process
simultaneously.
Three safety levels, one mechanical in the unit, other electronic in control interface and the third
one in the control software.


DAB. Data Acquisition Board:
PCI Data acquisition board (National Instruments) to be placed in a computer slot. Bus PCI.
Analog input:

  • Number of channels= 16 single-ended or 8 differential.
  • Resolution=16 bits, 1 in 65536.
  • Sampling rate up to: 250 KS/s (Kilo samples per second).
  • Input range (V)= 10V.
  • Data transfers=DMA, interrupts, programmed I/0. Number of DMA channels=6.

Analog output:

  • Number of channels=2.
  • Resolution=16 bits, 1 in 65536.
  • Maximum output rate up to: 833 KS/s.
  • Output range(V)= 10V.
  • Data transfers=DMA, interrupts, programmed I/0.
  • Digital Input/Output:
  • Number of channels=24 inputs/outputs.
  • D0 or DI Sample Clock frequency: 0 to 1 MHz.
  • Timing:Counter/timers=2. Resolution: Counter/timers: 32 bits.

 

PBCC/CCSOF.Computer Control+Data Acquisition+Data Management Software:
Compatible with actual Windows operating systems. Graphic and intuitive simulation of the process in screen.
Compatible with the industry standards.
Registration and visualization of all process variables in an automatic and simultaneously way.
Flexible, open and multicontrol software, developed with actual windows graphic systems, acting
simultaneously on all process parameters.
Management, processing, comparison and storage of data.
Sampling velocity up to 250,000 data per second guaranteed.
Calibration system for the sensors involved in the process.
It allows the registration of the alarms state and the graphic representation in real time.
Comparative analysis of the obtained data, after the process and modification of the conditions during the process.
Open software, allowing to the teacher to modify texts, instructions. Teacher’s and student’s
passwords to facilitate the teacher’s control on the student, and allowing the access at different work levels.
This unit allows that the 30 students of the classroom can visualize simultaneously all results and
manipulation of the unit, during the process, by using a projector.
Cables and Accessories, for normal operation.
 

Manuals:
This unit is supplied with 8 manuals: Required Services, Assembly and Installation, Interface and Control
Software, Starting-up, Safety, Maintenance, Calibration & Practices Manuals.
