What function do sensors perform in control systems?

Sensors play a critical role in control systems by collecting data from the environment. They measure physical phenomena such as temperature, pressure, flow, and level, converting these measurements into electrical signals that can be interpreted by the control system. This data is vital for the system to understand the current state of the environment it is controlling or monitoring.

By providing accurate and real-time information about the conditions being controlled, sensors enable the control algorithm to make informed decisions and adjust the operation of actuators accordingly. Thus, their function is foundational to the proper functioning of automation systems, as they ensure that the system has the necessary information to maintain desired performance levels.

Understanding the role of sensors emphasizes the importance of accurate and reliable data collection in effectively managing control processes.
