Process control acronyms

    • What are control process terms & definitions?

      The most common control process terms and definitions are: Process: Is the physical systems to control or measure. Examples: water filtration systems, steam boiler systems, oil refinery units, power generation units, molten metal casting systems, etc. Process Variable, or PV: Is the specific quantity measured in a process.

    • What are the different types of control systems?

      The most common classes of control systems are: the open loop control systems and the closed loop control systems. The open loop control systems mean there are no feedbacks from the con- trolled condition; in other words, no information is sent back from the process or system.

    • What is a process control switch?

      4. PROCESS CONTROL INSTRUMENTATION: Process Control Switches: Process switches generate an onor offoutput based on a change in variable phenomenon, commonly used in the process control industry to monitor physical quantities such as flow, speed, temperature and pressure.

    • What is a process control narrative?

      Process Control Narratives process control narrative, or PCN, is a functional statement describing how device-mounted controls, panel mounted controls, PLCs, HMIs, and other processor-based process control system components should be configured and programmed to control and monitor a particular process, process area or facility.

      The control devices usually take one of the following forms: Control valves (example, for throttling the flow rate of a fluid); Electric motors; Electric heaters. The measurement devices and the final control devices connect to some physical system which is called “the process”. To show this as a general block diagram: 2.
