Training System Temperature Control

Model HV-EXP4455

Technical Description:-

This compact teaching / training  unit offers every opportunity to learn the fundamentals of process control through experimentation on a temperature control system. The  experimentation set-up is mounted on a solid housing which accommodates  all the electronics. A metal bar, which is thermally insulatedwith  cladding,is heated or cooled at one end by a Peltier element. Three  temperature transducers along the axis of the bar allow the variation in temperature along the length of the bar, and hence the associated  thermal lags,to be obtained for differing operating conditions. A  dial-gauge thermometer offers the advantage that the temperature can be  read off directly at any time. The temperature ismeasured using a  thermal resistor (PTC). The transducer output signal is sent to the  software controller. Theoutput signal from the controllerinfluences  the operating voltage of the Peltier element andhence the heating  power. A fan that dissipates part of the heating energy can be activated by the software to investigate the influence of disturbance variables.   The powerful state-of-the-art software is an integral part of the training  system, embodying the principle of hardware/software integration (HSI).  It enables the experiments to be conducted and evaluated in a  user-friendly manner. The software has network capability. The link  between the practice system and the PC is made via a USB port.  The  clearly structured instructional material sets out the technological  fundamentals and provides a step-by-step guide through the experiments.
