Module 7Module 7Unit 23 – Instrumentation and Control Drawings

Learning ObjectivesLearning Objectives• Describe the types of control diagrams.• Identify symbols used on fluid power

diagrams.• Recognize supplementary information

accompanying circuit diagrams.• Read a graphic diagram.• Interpret graphic diagrams for fluid control

devices.

Graphic DiagramGraphic Diagram• Components and piping are shown as

schematic symbols

Pictorial DiagramsPictorial Diagrams• Components are shown in a pictorial form

and piping shown as lines

Cutaway DiagramsCutaway Diagrams• Components are shown in a cutaway form• Emphasizes the internal functions and

connections

Instrumentation andInstrumentation andControl Diagram Control Diagram TerminologyTerminology• Accumulator: Container in which fluid is

stored under pressure as a source of fluid power

• Actuator: Device for converting fluid power energy into mechanical energy (i.e., motors and cylinders)

• Circuit: Complete path of flow in a fluid power system

Instrumentation andInstrumentation andControl Diagram Control Diagram TerminologyTerminology• Component: Single hydraulic or pneumatic

unit• Control: Device used to regulate the

function of a component• Enclosure: Housing for components

– Indicated by a phantom line rectangle in diagrams

• Fluid: A liquid or gas

Instrumentation andInstrumentation andControl Diagram Control Diagram TerminologyTerminology• Port: End of a passage in a component• Reservoir: Container for storage of liquid

in a fluid power system not under pressure• Restriction: Area in a line or passage with

a reduced cross section that produces a pressure drop

Fluid Power Diagram Fluid Power Diagram SymbolsSymbols• In a diagram, lines can be solid or dashed

and may include dots or arrows to assist the print reader with interpreting the circuit

Fluid Power Diagram Fluid Power Diagram SymbolsSymbols• In a diagram, there are various symbols

for units such as motors, heaters, coolers, accumulators, etc.

Fluid Power Diagram Fluid Power Diagram SymbolsSymbols• In a diagram, there are various symbols

for springs, switches, and other operating buttons

Fluid Power Diagram Fluid Power Diagram SymbolsSymbols• In a diagram, there are various symbols

for valves and other flow-control devices

Pneumatic Diagram Pneumatic Diagram ExampleExample• Refer to the sequence of operations on

pages 403–405 of text for this circuit
