CAT NO: DIDACTICNLE-Export-210018
Pressure 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 pressure control.
All
components are clearly laid out on a vertical front panel. The
large-format process diagram provides an aid to understanding.
The
controlled system is operated by compressed air, which must be provided
by the laboratory. The use of two in-line pressure vessels permits a 2nd
order control system to be constructed. Disturbances can be generated
by alternate air tapping by way of a hand-operated valve. Both pressure
vessels are fitted with manometers. An electronic pressure transducer
measures the pressure. The controller used is a state-of-the-art digital
industrial controller. The actuator in the control loop is an
electro-pneumatic control valve. 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.
