A '''process variable''' is the current status of a process under control. An example of this would be the temperature of a furnace. The current temperature is called the process variable, while the desired temperature is known as the [[setpointset-point (control system)|setpointset-point]].

Measurement of Process Variables are important in [[controlling]] a process. The Process Variable is a dynamic data which changes rapidly. So it becomes necessary to measure process variables for the maintenance of accuracy in a process.Generally three type of variables are there Pressure,Temperature,Composition Which affects the Chemical or Physical Process Which also called Process Parameter.
