Process control System

A process control system is a set of tools and techniques that are used to monitor and control industrial processes. It involves the use of hardware and software components that work together to collect data, analyze it, and make adjustments to the process as needed. Here are some key components of a process control system:

Sensors and actuators – these are physical devices that are used to measure variables such as temperature, pressure, flow rate, and level. Actuators are used to control variables such as valves, pumps, and motors.

Programmable Logic Controllers (PLCs) – these are specialized computers that are used to automate industrial processes. They receive input from sensors and use logic to make decisions about how to control the process.

Human-Machine Interface (HMI) – this is a graphical user interface that allows operators to monitor and control the process. It typically displays data from sensors and provides controls for adjusting variables such as setpoints and alarms.
