In a control system, what function does the 'Sensor' perform?

The function of the 'Sensor' in a control system is to measure the output of the system. Sensors play a crucial role in providing real-time data about the performance and status of various components within the system. By measuring specific variables, such as temperature, pressure, or speed, sensors collect the necessary information that helps in assessing how well the system is functioning in relation to its intended objectives.

This information is essential because it allows other components of the control system to interpret how the actual output compares to the desired output or targets. The accuracy and reliability of the sensor data are fundamental for making informed decisions regarding system adjustments and ensuring overall efficiency. Therefore, the sensor is key to monitoring performance and ensuring that the control processes can respond appropriately based on the measured outputs.
