Introduction. SAMA is an acronym
standing for Scientific Apparatus Makers Association
, referring to a unique form of diagram used primary in the power generation industry to document control strategies.
What is SAMA symbols?
SAMA symbols are
used to develop and convey the complex functional interworking of boiler control loops
. The four most common control loops used in industry are temperature, pressure, level, and flow loops. Each of these loops is comprised of just three devices: a transmitter, controller, and control valve.
What is a SAMA diagram?
SAMA is an
acronym of Scientific Apparatus Makers Association
, in some plants, there has been greater adoption of SAMA diagrams which provide more detailed process diagrams which constitute various process symbols. SAMA drawings are sometimes referred to as “control functional diagrams”.
What is Sama symbology and ISA symbology?
The SAMA and ISA versions also use different symbols to
represent the flow control valve (FCV-xxx)
. A SAMA diagram uses various types of enclosure symbols to represent the various elements or functions of the control system, see Table 1. Enclosure symbols are tied together by continuation symbols, see Table 2.
What is ISA symbology?
The Instrumentation, Systems, and Automation Society (ISA) is one
of the leading process control trade and standards organizations
. The ISA has developed a set of symbols for use in engineering drawings and designs of control loops (ISA S5. 1 instrumentation symbol specification).
What is a SAMA?
Introduction. SAMA is an acronym standing for
Scientific Apparatus Makers Association
, referring to a unique form of diagram used primary in the power generation industry to document control strategies. … SAMA diagrams may show varying degrees of detail about the control strategies they document.
What is logic diagram in instrumentation?
Control Logic Diagram – A diagram that
provides easy to read graphic representation of the operation of individual system equipment controls using basic digital logic symbols
. These symbols functionally relate manual and process input action to the process control and operator display output actions.
What is a loop sheet?
Instrument loop diagrams are also called instrument loop drawings or loop sheets. These set of drawings are more detailed than process and instrument diagrams (P&IDs). Loop diagrams are
the most detailed form of diagrams for a control system
and thus it must contain all details omitted by PFDs and P&IDs alike.
What is difference between P&ID and PFD?
Generally, a Process Flow Diagram shows only the major equipment and doesn’t show details. PFDs are used for visitor information and new employee training.
A Process and Instrument Drawing (P&ID) includes more details than a PFD
. It includes major and minor flows, control loops and instrumentation.
What is a Ice symbol of?
It is a symbol of
rigidity, frigidity, the waters of the earth
as opposed to the fresh and living WATER of the fountain of Paradise. It is coldness, absence of love, difficult and unexplored territory not conducive to human life and life in general.
What are P&ID symbols?
P&ID is an abbreviation meaning ‘
Piping and Instrumentation Diagram
‘. Piping and Instrumentation Diagrams are graphical representations of a process system. These are fundamental to every standardized engineering project. These two-dimensional diagrams function as a blueprint for the engineering system’s design.
What does Sama mean in Persian?
Sama (Turkish: Sema, Persian, Urdu and Arabic: سَمَاع – samā’
un
) is a Sufi ceremony performed as dhikr. Sama means
“listening”
, while dhikr means “remembrance”.

What are the logic diagram?
logic diagram A
diagram that displays graphically
, by interconnection of logic symbols, the digital design of a logic circuit or system.
What is the purpose of a logic diagram?
The use of logic symbology results in a diagram that
allows the user to determine the operation of a given component or system as the various input signals change
. To read and interpret logic diagrams, the reader must understand what each of the specialized symbols represent.
