Flow Control Trainer- Engineering Lab Training Systems Description and Specifications for Lab Tenders
Flow 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 flow control.
A
pump transfers water from a storage tank through a piping system. The
flow rate is measured by a electromagnetic flowmeter, which permits
further processing of the measured value by outputting a standardised
current signal. A variable-area flowmeter indicates the flow. The
controller used is a state-of-the-art digital industrial controller. The
actuator in the control loop is a control valve with electric motor
operation. A ball valve in the outlet line enables defined disturbance
variables to be generated. 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.
