Instrumentation And Control Engineering Basics |verified| -

The quantity of fluid moving per unit time (liters/minute or kg/hour).

The primary goal of I&C is to minimize the error between a process's actual output and its desired set point. This is achieved through two main types of control loops:

A separate, independent control system whose only job is to shut things down safely when the main control system fails. instrumentation and control engineering basics

Unlike a simple on/off tap (like a light switch), a control valve can be 25% open, 62% open, or fully open.

Unlike software engineering, where a bug crashes an app, an instrument failure can kill people or cause an environmental disaster (e.g., Bhopal, Deepwater Horizon). The quantity of fluid moving per unit time

. The controller compares this data against a desired "Setpoint." Correction (Act):

Process the raw sensor signal and convert it into a standardized transmission signal (e.g., , 0–10 V, or digital fieldbus protocols like HART, Modbus, Foundation Fieldbus). The 4–20 mA standard is preferred because 4 mA indicates zero (allowing open-circuit detection) and current is immune to voltage drops over long cable runs. Unlike a simple on/off tap (like a light
