The Computer Controlled Process Control Unit for the Study of Pressure (Air), "UCP-P", consists of a compressed air duct whose flow is controlled by a pneumatic valve (the compressed air or gas source is not included).
The air is supplied through the air inlet and it can be diverted with two pressure regulators toward the circuit which controls the valve or the circuit where the pressure and flow will be controlled.
The valve control circuit is composed by an I/P converter, which transforms the electrical signal send by the computer in a pneumatic signal, and a manometer placed between the I/P converter and the valve.
The main circuit, whereby the flow and pressure will be controlled, is composed by an absolute pressure sensor and a manometer to control the pressure, an orifice plate with a differential pressure sensor and a flowmeter to control the flow and four manual valves to introduce disturbances in the system and to change its configuration adding an air tank to the duct for the study of the volume effect in the control system.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
