CAT NO: DIDACTICNLE-Export-210019
Temperature Control Demonstration Unit- Engineering Lab Training Systems.
Technical Description
This training system provides
a comprehensive experimental introduction to the fundamentals of
process control using an example of temperature control.
All
components are clearly laid out on a vertical front panel. The
large-format process diagram provides an aid to understanding.
The
system comprises two water circuits. In the secondary circuit fresh
water is heated up by a heat exchanger. The temperature is measured by
an electronic temperature transducer at the fresh water outlet. The
outlet temperature of the fresh water is regulated by the flow rate of
warm water in the primary circuit. The primary circuit comprises an
electrically heated tank, a pump and an electromagnetic proportional
valve as the actuator. Both circuits include variable-area flowmeters.
The controller used is a state-of-the-art digital industrial controller.
A ball valve in the secondary circuit enables defined disturbance
variables to be generated. The controlled variable X and the
manipulating variable Y can be tapped as analogue signals at lab jacks.
This enables external recording equipment, such as a plotter or an
oscilloscope, to be connected.
An instrumentation and control
software with interface module (USB) is available as an accessory. This
enables the key process variables to 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.
