MC Flashcards
Device that measures, monitors, and control process variables
INSTRUMENT
It refers to the regulation, command or direction of all aspects of the process
CONTROL
Branch of physics which deals with the measuring, monitoring and controlling variables in a process
INSTRUMENTATION AND CONTROL
refers to the methods of changing or refining raw materials to create end products
PROCESS
The regulation or manipulation of variables influencing the conduct of a process in such a way as to obtain a product of desired quality and quantity in an efficient manner.
PROCESS CONTROL
An arrangement of two or more instruments connected together to perform a unified task.
INSTRUMENT LOOP
A value for a process variable that is designed to be maintained.
SETPOINT
Output signal generated in response to a change of a process variable.
CONTROLLER OUTPUT
The determination of the magnitude of a variable.
MEASUREMENT
The determination of the existence or the presence of a variable.
DETECTION
The limit or extent of variation. The lower limit is called LRV & the upper limit is called URV.
RANGE
The number of units between two, the LRV and URV.
SPAN
A signal that has no discrete positions or states and changes value.
ANALOG SIGNAL
A mechanism or device used to alternate between different measurement processes or tasks within an instrument or a control system.
PROCESS SWITCH
Refers to the capability of the instrument to measure a variable.
