Computerized Temperature Control Trainer
Product Code : EL-MAILE-10804
Quick Answer: The Computerized Temperature Control Trainer is a closed-loop process control trainer that demonstrates industrial temperature control using real control-engineering components. A 3-stage circulating pump (70W, 3,6m3/h, 4m head) circulates water within a closed circuit past a screw-in heater (2kW) and a heat exchanger with fan (approx. surface area 2,8m2; fan 250W, 780m3/h, 430Pa, 2880min-1), with three integrated thermocouples (type J, 0…200°C) providing temperature measurement and a hand-operated valve available to adjust the flow rate of water; dead times can be represented by using different lengths of process delay. A thyristor power controller (max. load current 25A) acts as the actuator, driven by a state-of-the-art digital industrial controller that can be configured as a continuous or a switching device to activate the heater via the actuator and/or the fan, with the controlled variable X and manipulating variable Y plotted on an integrated 2-channel line recorder or tapped as analogue signals at switch-cabinet lab jacks for connecting external recording equipment such as an oscilloscope or flatbed plotter; process control software is optionally available.
A circulating pump delivers water within a closed circuit, and a hand-operated valve can adjust the flow rate of water; dead times can be represented by the use of different lengths of process delay. A thyristor power controller is used as the actuator, and the controller used is a state-of-the-art digital industrial controller, which 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; the loop also contains a screw-in heater, a heat exchanger with fan, and three integrated thermocouples for temperature measurement. Alternatively, the variables can be tapped as analogue signals at lab jacks on the switch cabinet, which enables external recording equipment, such as an oscilloscope or a flatbed plotter, to be connected; process control software is optionally available.
