The "BS5-PLC" has been designed to study the temperature measurement techniques inside a sealed place, such as an oven and how to perform a temperature control through a PLC. This unit is equipped with an oven that contains a heating element and a changeable speed fan than enables to modify the oven time constant. The oven has four equal thermocouples placed on different heights, a platinum heating element thermometer, a thermistor and a semiconducting mechanism sensitive to temperature. One of the temperature sensors output signals is conditioned to be connected to the PLC. The temperature inside the oven can be controlled with a PLC through the signal obtained from a sensor.
*Available PLC models of different manufacturers: PANASONIC, SIEMENS, OMRON, MITSUBISHI, ALLEN BRADLEY, etc.
