With the introduction of CAPTURE, machines that were once costly, cumbersome and difficult to use became affordable, space-saving and easy to use. Now CAPTURE MKII takes the concept forward into new realms of student understanding, adding superb visibility of the working of the bmachines and taking full advantage of the latest software and instrumentation techniques. All the CAPTURE units use standard PCs to display, record and manipulate the data. All Armfield CAPTURE units are now supplied with Armfield Armsoft LabVIEW™ based software to present and record the data in a way that is straightforward to use and understand for the student, yet offers a wide range of advanced features and capabilities. A common software format is used accross all machines. Similarly the machines all use a common interface unit, thus providing a cost-effective solution for laboratories requiring several machines.
The interface between the CAPTURE MKII units and the user's computer is provided by the Armfield IFD7 Interface Unit. The IFD7 is an essential accessory to the Armfield FM Series CAPTURE range of engineering education teaching equipment. This accessory conditions the raw data from the sensors of the equipment, digitises the data and transfers it to the computer using the USB interface. It also includes a sophisticated three phase inverter for providing accurate motor speed control, and a second motor drive output, all under software control.
The FM40 is a radial flow machine, which produces the necessary pressure to move gas by the centrifugal force built up inside the fan casing. The design of the fan blade has a primary influence on performance.
These types of fans are usually employed for ventilating duties requiring a somewhat higher delivery pressure than that available from axial fans.
Key Features
The FM41 produces gas flow by virtue of the momentum changes imparted across the rotary blades, parallel to the axis of rotation. Such fans are more suitable for higher flows at lower delivery pressures than their centrifugal counterparts.
Comparison of the performance characteristics of the FM41 Axial Fan with those of the FM40 Centrifugal Fan thus provides an instructional exercise of valuable practical application.
Key Features
The FM42 demonstrates, on a small scale, the use of a multi-stage centrifugal compressor, as used in industry for high pressure deliveries of gas flows or suction duties.
Multi-stage compressors are used industrially for high pressure deliveries of gas flows or suction duties. The kinetic energy imparted to the gas by the impeller rotation is converted into pressure energy, which progressively increases from stage to stage.
Key Features
The Armfield Industrial Division designs and manufactures research & development systems, primarily for the food, beverage, dairy, edible oil and pharmaceutical industries. Used by many of the world's leading corporations, Armfield systems enable researchers and product developers to replicate full-scale industrial manufacturing processes on a miniature-scale in the laboratory.
