    Fast rise time

    AMADA Transistor-controlled welding power supplies have rise times 4.5 times faster than that of conventional* models. high quality welding can be accomplished in a short period of time on small work pieces.
    * Compared with conventional model MD-1500E

    No welding transformer needed

    The welding current is directly controlled with fast switching by transistor, so no welding transformer is required.

    Built-in pre-check function

    Applying current on the workpiece before the main current, it is possible to judge whether or not there is a workpiece set on the electrodes, and to evaluate the status of workpiece.

    Polarity switchable type

    This can eliminate the Peltier effect (polarity effect) and provide uniform nugget diameters on series welding.

    Two-channel type

    Two weld heads can be controlled by one power supply. It contributes to cost and space savings.

    S16 configured as an open channel showing flow over an elevated section of the bed with a hydraulic jump forming on the downstream slope. It demonstrates flow through both open channels and closed conduits when coupling this highly visual accessory with the F1-10 Hydraulics Bench. It has a unique elevating bed section and models of various hydraulic structures enable the difficult concepts of critical flow and energy changes to be clearly demonstrated and analysed. It also has a working section large enough for the various flow phenomena to be seen clearly by a group of students – enables a teacher to provide practical demonstrations at the same time as explaining the theory. The demonstrations can be set up quickly and easily, including varying the upstream and downstream flow conditions. It is ideal for student project work – user constructed models of different hydraulic structures can be evaluated.

  • Armfield – Desktop Learning Modules – DLMX Series

    ...

    The Armfield DLMX system is a practical education system aimed at teaching students the basics of fluid mechanics, heat exchange and other fundamental engineering principles. It is a unique combination of coursework and practical demonstration equipment and can be used to teach students of all ages. The equipment comprises a small battery operated base unit, into which one of seven different cartridges is plugged. The base unit contains a water reservoir, pump, controls and viewing panel. The cartridges contain an experimental representation of the topic, and the specific instrumentation required for the particular demonstration. Currently seven different cartridges are available covering fluid mechanics, thermofluids and heat transfer. The cartridges can be changed in seconds as they use a simple plug in mechanism. As the cartridges include their own microcontroller, the base unit automatically detects the cartridge that is fitted and displays the information accordingly. The equipment can be used by a single student, by small groups of students or by a teacher or technician demonstrating to the whole class. The academic content and coursework is provided by Washington State University. It includes classroom exercises, detailed theory of the processes and suggestions for further work. The base unit comprises a clear acrylic water reservoir, mounted on a robust vacuum formed ABS plastic plinth. Under the plinth is a pump with a variable speed control, flow meter, battery, level sensor and the electrical control circuitry with display. The units are battery powered; the internal rechargeable batteries provide more than enough for a long classroom session. The units can also be powered by mains electricity, recharging the batteries at the same time. The simple push fit cartridge interface, provides smartchip and self-sealing hose connections. This mechanism is common to all the DLM cartridges. The quick easy setup ensures that sensible investigations can be performed in less than ten minutes.

  • Armfield – Fluid Machines – FM Series CAPTURE

    ...

    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.

  • Armfield – Heat Transfer – HT10XC Computer Controlled Heat Transfer Teaching Equipment

    ...

    The Armfield HT10XC is a computer controlled service unit, which can be used in conjunction with a range of small-scale accessories for a wide range of demonstrations into the modes of heat transfer. The factors that affect heat transfer can be investigated and some of the practical problems associated with the transfer of heat can be clearly demonstrated. The heat transfer accessories may be individually connected to the HT10XC service unit, which provides the necessary electrical supplies and measurement facilities for investigation and comparison of the different heat transfer characteristics. A specific feature of the HT10XC is that it corporates the facilities and safety features to enable the accessories to be remotely controlled from an external computer, where this is appropriate. It will shut down safely in the event of a communications failure. With suitable (user provided) software, the equipment operated remotely, for instance over an intranet or even over the internet. All the facilities can also be accessed locally using the front panel controls and display.

    The service unit is housed in a robust steel enclosure and designed for use on a bench or table. It provides control outputs to the accessories, and instrumentation inputs from the accessories.

    Outputs:

    • A stabilised, variable DC supply to the heater of the heat transfer accessory under evaluation
    • Drive to flow-regulation valves on HT11C and HT12C
    • Drive to the variable-speed air blowers used on HT14C and HT16C

    Inputs and Instrumentation:

    • Temperatures: (up to 10 off, dependant on accessory being used)
    • Heater voltage: (All accessories except HT17)
    • Heater current: (All accessories except HT17)
    • Heat radiated: (HT13)
    • Light radiated: (HT13)
    • Air velocity: (HT14, HT14C, HT16, HT16C,HT19)
    • Cooling water flowrate: (HT11C, HT12C, HT18C)

    In manual mode, the outputs listed above are under control of potentiometers on the front panel of the unit. In remote mode the outputs to the accessories are controlled by the computer. A ‘Watchdog’ system is implemented in remote mode to ensure operator and equipment safety in event of a computer or communications failure.

    In both modes the signals from the accessory can be shown on the front panel displays. Selector switches are used to select the chosen signal onto one of the two displays. These signals are also available on the USB interface for datalogging on the computer (even if the computer is not controlling the equipment).
