In control theory, a process variable (PV; also process value or process parameter) is the current measured value of a particular part of a process which is being monitored or controlled.

Apr 9, 2019 · In almost all industrial process applications, control of process variables is critical to the safe and efficient operation of the process. The most common variables controlled are pressure, …

Manipulated Variable: a variable that we can control in the process and directly affects the output of the process. Process Variable: the variable in the system or process that we desire to control.

ifference between success and failure. Process control begins w h understanding your process variables. In manufacturing, a wide number of variables from temperature to flow to ressure can be …

The controlled quantities (or controlled variables) are those streams or conditions that the practitioner wishes to control or to maintain at some desired level. These may be flow rates, levels, pressures, …

Mar 1, 2024 · In conclusion, these four major process variables – pressure, temperature, flow, and level – form the cornerstone of industrial instrumentation. Their accurate measurement and control are …

Control the process by monitoring and adjusting key variables. But what are these process variables, and why are they so crucial? This article explores the top five process variables most commonly …

Common process variables include temperature, pressure, flow rate, and liquid level, which vary depending on the specific production process in a chemical plant.

Basic process control elements include flow meters, pressure and temperature sensors, control valves, and other tools that measure process parameters or directly affect the process. Process control …
