Amatrol's T-5554 (Analytical Process Control Learning System)
In the chemical industry, the necessity of control systems for analytical processes has always existed. Control systems allow the determination of process composition streams and the control of the output product, monitoring and controlling the complete process.
According to the American Chemical Society, analytical chemistry allows to obtain, process and communicate information about the composition and structure of matter, the processes perform qualitative and quantitative analysis and in order to obtain feasible information it is necessary to set error limits, validate and verify results through proper calibration and standardization. The precision of the measurements is very important because a correct analysis depends from it; therefore, many analytical methods have evolved from manual systems to automated control systems, reducing the percentage of error during the measurement and the calibration.
The growth of automated systems for chemical purposes has increased considerably in the past years, because of this, it is imperative to understand the operation method of these control systems not only from the chemical point of view, but with an automation approach. Figure 1 shows the system that will be used for the purpose of understanding automated processes; this system is located in the automation laboratories of the Instituto Tecnológico de Estudios Superiores de Monterrey Campus Estado de México. It is the Amatrol's T-5554 Analytical Process Control System, which has the function of controlling the pH of the mixture of two different chemical solutions. The following figures show the different elements of the system that are used for the process including the system control panel, equipment's power switch, the chemical storage tank and pump for the acidic solution, the agitation tank, the chemical storage tank and pump for the basic solution, the rotameter, pipes and valves, and an internal view of the control panel.

The main objective of the website is to present the work made in order to understand and use the Analytic System. The different tabs will contain information regarding the P&I diagram, tests performed, open loop diagrams, closed loop diagrams and the tuning of a PID controller using the pole placement technique.
