  • PCI Interface Design Trainer

    The PCI application is now widely used and has replaced the ISA system. PC-based interfacing and I/O experimentation had been based on the ISA (Industry Standard Architecture) bus, however, the PCI (Peripheral Component Interconnect) bus, makes it much more difficult for users to interface their own circuits directly to the PC. The PCIDT rectifies this situation enabling the experiments to be carried out via the PCI bus.

    The PCIDT provides a solution for teaching PC-based interfacing to various I/O devices on modern PCs using the PCI bus. Pre-written experiments cover I/O devices from switches and 7-segment displays and A/D and D/A conversion to the optional DC and stepper motors. A complete introduction to PC interfacing covering PC interfaces and how to connect a range of common I/O devices is provides along with twelve experiments, with their program listings in assembly language and C, based on the PCIDT’s pre-wired circuits. Using the exercises in the textbooks and tools, users are able to learn quickly in controlling I/O under Windows through a PCI interface card. Users can develop and learn PCI I/O control, in addition experiments with C or VB language. The system contains two main units: the interface card and the experiment platform. The design ensures that none of the experiments require soldering. The unit is enclosed in a strong and durable case.

  • Transducer Trainer

    The TRT is a collection of four transducer trainers which include Optical, Temperature, Strain gauge and LVDT. The four different trainers help teach students an introduction into various elements of transducers. The strain gauge trainer uses a cantilever beam arrangement to produce strain on the strain gauge with weights placed on the free end of the cantilever. The seven-segment LED display shows strain in micro strain units. Different weights are provided to perform linearity and sensitivity experiments.

    The Optical Transducer comprises of various sensors and transducers which provides the basic knowledge for sensing light and signal conditioning of the signals received from the sensors and transducers. The Temperature Transducer trainer covers four different types of transducers. Experiments covering fundamental characteristics of transducers and the study of transducer controlled switching/alarm systems can be performed.

    The LVDT (Linear Variable Differential Transformer) is the most widely used inductive transducer for displacement measurement. LVDT is a secondary transducer which converts the displacement directly into an electrical output proportional to the displacement. The trainers seven-segment LED display shows displacement in mm with a sensitivity of 10mV/mm in the range of 10mm.
