physics which deals with the properties,
motions and behavior of air”

Noise level
The exhaust air is loud.
The problem is largely solved
with silencers.
Costs
Compressed air is a relatively
expensive means of conveying
power.
The high energy costs are
partially compensated by
inexpensive components and
higher performance.
Compressed Air as a
Working Medium
Advantages:
•Air is available everywhere
•Compressed air is easily conveyed in pipelines over large
distances
•Compressed air need not be returned
•Compressed air is insensitive to temperature fluctuations
•Compressed air is explosion proof
•Compressed air is clean
•Compressed air is fast
Compressed Air as a
Working Medium
Disadvantages:
•Straight line movement can be produced directly.
•Compressed air is a relatively expensive means of
conveying energy
•Compressed air requires good conditioning
•It is only economical up to a certain force
expenditure.
•Air is compressible. Exhaust air is loud (reduced by
using silencers).
•The oil mist mixed with air for lubricating purposes

Block diagrams are more
easily understood by a
layman. No knowledge of
symbols is necessary.
They are faster and easier
to draw.
Corrections are also easier
to make.
A block diagram can be
easily converted into a
circuit diagram.
Individual blocks in a
diagram may represent a
single item, or multiple
items, performing a certain
function.

conversion of supply energy into useful
work. They can be described Into two

The Rodless Cylinder
•Conventional Double Acting Cylinders require
space to house the cylinder.
•Plus space to carry out the work.
•More effective use of the available space can be
made by using Rodless Cylinders.

Classification of Sensors
Sensors are further categorized as either :
Binary
Analogue.
Binary sensors convert a physical quantity
into a binary signal which means it has
two switching states. The most common
being an electrical signal ONor OFF.

Inductive Proximity Sensors
•The bigger the coil, the greater the
active switching gap.
•Inductive sensors can only detect
metals.
•Different switching distances for
different metals
Selection Criteria
•They can be selected according to the
material which they are to detect.
•Metals of any kind can be detected
easily and economically with inductive
sensors if short switching distances
only are required (eg. 0.4 …. 10 mm)
Uses of Inductive Proximity Sensors
Inductive sensors detect metals and operate
quickly, reliably and tirelessly. They are used
to:
•Count
•Identify
•Detect
•Switch
•Control
•Check
•Distinguish
•Sort
•Position

Capacitive Proximity
Sensors
•Almost similar to the inductive sensor.
•Able to detect most materials.
•Switching distance adjustable.
Selection Criteria
Capacitive proximity sensors are
suitable for the detection of a wide
range of materials, but again only
for relatively small distances,
similar to inductive proximity
sensors.
Target
Capacitive Proximity
Sensors
Detection of matt, black objects.
Optical Proximity Sensors
There are three different
types of optical
proximity sensors:
•Through beam optical
sensor
•Retro-reflective optical
sensor
•Diffuse optical sensor
Solenoid valves
The directional control valves used in
electro pneumatics are similar to those
used in pure pneumatics. The only
difference is that they are actuated by
solenoids.
