Specifications

AFTC. Unit:
This unit allows the detailed study of fluid friction head losses which occur when a
fluid flows through pipes, fittings and flow metering elements.

AFTC/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 for -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. DMA channels=6.
Analog output:Number of channels=2. Resolution=16 bits, 1 in 65536. Max. 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.
AFTC/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. Student calibration system for all 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 to 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.
