Temperature Control Trainer- Engineering Lab Training Systems Description and Specifications for Lab Tenders
Temperature Control Trainer- Engineering Lab Training Systems.
Technical Description
This teaching and training
system provides a comprehensive experimental introduction to the
fundamentals of process control using an example of temperature
control.
A circulating pump transfers water within a closed
circuit. The flow of water can be regulated by a hand-operated valve.
The loop also contains a screw-in heater, a heat exchanger with fan, and
three integrated thermocouples for temperature measurement. Dead times
can be represented by the use of different lengths of process delay. A
thyristor power controller is used as the actuator. The controller used
is a state-of-the-art digital industrial controller. It can be
configured as a continuous or a switching device, and can activate the
heater via the actuator and / or the fan.
The controlled variable X
and the manipulating variable Y are plotted directly on an integrated
2-channel line recorder. Alternatively, the variables can be tapped as
analogue signals at lab jacks on the switch cabinet. This enables
external recording equipment, such as an oscilloscope or a flatbed
plotter, to be connected.
A process control software is
optionally available. The software permits the construction of a
complete networked system comprising multiple trainers from the series.
The key process variables can also be represented, and control functions
executed.
The well-structured instructional material outlines the
technological fundamentals and provides a step-by-step guide through the
experiments.
