• Optional items: 7, 8, 9, 10 and 11.

• Let us describe first the main items (1 to 6):

• 1 ATENG 11842. Unit:
  Bench-top unit.
  Anodized aluminum frame and panels made of painted
  steel.
  Main metallic elements made of stainless steel.
  Diagram in the front panel with distribution of the elements
  similar to the real one.
  Centrifugal fan with computer controlled speed, speed

• range: 0 – 3000 rpm.

• Aspiration transparent duct:

• Inner diameter: 114 mm.
  Includes a butterfly valve to regulate the air flow and an
  orifice plate with air flow measurement.

• Discharge transparent duct:

• Inner diameter: 144 mm.
  Includes a butterfly valve to regulate the air flow.
  The unit is supplied with a set of three interchangeable

• turbines:
  With the blades curved forwards.
  With the blades curved backwards.
  With perpendicular blades.

• Instrumentation:

• Speed sensor, range: 0 – 3000 rpm.
  Wattmeter.

• Three differential pressure sensors to measure:
  The differential pressure in the aspiration duct.

• Unit: ATENG 11842
  The differential pressure in the discharge duct.

• The air flow through the orifice plate; range: -25 – 25 mm H O.

• To know the inlet air conditions:
  “J” type temperature sensor.

• Pressure sensor, range: 0 – 1.1 atm.

• Humidity sensor, range: 0 – 100 %.

• The complete unit includes as well:
  Advanced Real-Time SCADA.
  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 and remote control for 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.
