Temperature Control Trainer (Experimentation)

DESCRIPTION The Temperature control trainer is designed for teaching the basic temperature control principles study in chemical and instrumentation engineering. For ease of understanding, the product is described with its major components. INTRODUCTION Temperature control loops are usually moderately slow because of the sensor lags and the process heat transfer lags. PID controllers are often used. Proportional band settings are fairly low, depending on temperature transmitter spans and control valve sizes. The reset time is of the same order as the processing time constant i.e., the faster the process, the smaller T1 can be set. Derivative time is set as something like one-fourth the process is time constant, depending on noise in the transmitter signal. Aim To study the performance of Open loop/P/PI/PD/PID controllers on temperature process
