pH Control – PLC On-Board
This bench top unit consists of a stirred reactor that is fed with an acid solution by a metering pump.
Controlling the flow rate of another metering pump that sends basic solution into the reactor will enable to control the pH inside the reactor.
The on-board PLC includes a PID algorithm block and is able to manage the unit through an Ethernet communications module.
This module allows the PLC to work together with an operator panel for the information exchange.
The panel has several graphic pages, with the unit synoptic diagram, the open and closed control loop main parameters, and the graphic of the system response according to the working situations.
This unit enables to develop and analyze the following subjects:
- Proportional, Integral and Derivative control
- Setup of controllers
- Response and characteristics of the process
- Determining dead time
- Tuning the controller
- Calibrating a pH-meter
Supplied with Theoretical – Experimental Handbook
