Process controllers are a set of tools or instruments that measure different parameters like temperature, pressure and voltage of the process of forming a product. Process controllers control the process by comparing it against the standards and in case of deviation (or on reaching the set standard), alert the operator or, if programmed they rectify the deviation.

The tools for the measurement include sensors, cables, input terminals, software, control panels and output terminals. The process controllers are a necessary component in almost all the production processes in a modern industry.

Some important parameters you must consider before you select process control systems are:

1. The production process you are following or want to follow
2. Important parameters of the process
3. The choice of automated process controllers or human-machine linked process
