1. What are the key elements of Mechatronics
and display devices
and data acquisition
2. Mention the
functions of a Mechatronics system.
It allows to integrate the mechanical systems with micro
electronics to obtain the process design automation
It ensue the higher efficiency and reliability for
the quality of products 3. What do you understand by signal conditioning?
A signal conditioning mans manipulating an analog
signal in such a way that it meet the requirement of the next stage for further
4. Give an example for a transducer and state
its transduction principle.
Transducers are device which
converts an input of one form of energy into an output of another form of
5. List any
four types of sensors and mention their features.
1.based on power
requirements passive and active
2.based on the type of output analog and digital
3.Based on sensing primary and secondary
6. State the
advantage of capacitive type proximity sensor.
capacitors are noiseless
high accuracy high sensitivity high resolution
7. What is
RTD? State its applications.
It is sensor used to measure the
temperature by correlating the resistance of the rtd element of temperature
process temperature control(textile, chemical ,food)
temperature control(test chamber , oven temperature)
down the type of proximity sensor . optical encoders
capacitive sensors proximity switches
9. Distinguish between position sensors and
light sensors .
A position sensor is used to monitor the position
of the throttle in an IC engine. Its located on the spindle so that it can
monitor the position of the throttle
The light sensors enables a robot to detect light
. Its uses cadmium sulfosolenide (cds)photoconductive photocell. The light
sensor can give the robot vision and make it easier for it to operate
are the elements of the closed loop control system?
The various elements of a closed loop control
system are, a. Comparison element b. Control element c. Correction element d.
Process element e. Measurement element
are the two types of feedback loop?
The two types of feed back loop are, a. Positive
feed back loop b. Negative feed back loop. "The feedback is said to be
negative/positive feedback when the signal; which is feed back, subtracts/adds
from the input value. It is required to control a system. The control elements
decide what action to take when it receives an error signal"
are the types of control elements?
two types of control elements. They are
are the main applications of mechatronics?
Washing machines, dish washers, micro ovens,
cameras, camcorders, robots, automatic conveyors, computer-controlled machines
Obtain the basic functions of control systems.
minimize the error between the actual and desired output
the time response to load changes in the system
What are the types of control system?
down the requirements of control systems.
Give an example for open loop system and closed
loop systems. 1. Closed loop system – Automatic water level controller
2. open loop system - Electric fire
Compare open loop control system and closed loop
control system. Open loop systems

about the Mechatronics approach in a micro-processor – controlled washing
In the microprocessor-controlled washing machine,
a mechanical system has become integrated with electronic controls. As a
consequence, a bulky mechanical system is replaced by a much more compact
microprocessor system, which is readily adjustable to give a greater variety of
is the larger scale application of Mechatronics?
A larger scale application of Mechatronics is a
Flexible Manufacturing engineering System (FMS) involving computer – controlled
machines, robots, automatic material conveying and overall supervisory control.
List some of the applications of Mechatronics?
Appliances: Washing machine, Bread machines etc
Automobile: Electrical fuel injection, Antilock brake system
Aircraft: Flight control, Navigation system
