COMPUTERIZED TEMPERATURE CONTROL TRAINER
MODEL NO-IM-013
DESCRIPTION
The ”LabTek” Trainer provides a comprehensive experimental introduction to the fundamentals of control engineering using an example of temperature control.
A circulating pump delivers water within a closed circuit. A hand-operated valve can adjust the flow rate of water. 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.
Process control software is optionally available.
