Latest Mechatronics Engineering Interview Questions
1.As a mechatronic supervisor in field,& as a graduate student of mechatronic, what we have to know? Mean topics, matters & other things?
Mechatronics engineer is like a joker, he can play many rules according to his wide knowledge fields he knows.
you should have basics of
1. Back ground of how some systems work
2. system components (Sensors, Actuators, Controllers)
3. Electronics
4. CNC Machines
5. MC & plc
2.Explain encoder definition?
An encoder is a device, circuit, transducer, software program,algorithm or person that converts information from one format or code to another, for the purposes of standardization,speed, secrecy, security, or saving space by shrinking size.
3.WHAT IS DIFFERENCE BETWEEN PRESSURE VESSEL & COLUMN?
The Pressure vessels (cylinder or tank) are used to store fluids under pressure.If the pressure vessel are design in the form of column to separate the gas at upper portion and liquid is collected at bottom so called column generally a pressure vessel (column)
4.Would you say me selecting Mechatronics Engineering will be useful to my career in this present society?
mechatronics engg will be usefull to compony because you may select machanical engg for mechanical
maintenance and u may select electronics engg for electronics maintenance .but mechatronics engg can handle both. so you may help your compony in this cost cutting timing.
5.What is difference between PLC and Logic Card?
there is no diffrence… technically Both are logic controller… used for so many applications and in PLC has it’s own internal memory ( compared to Logic card ) Logic card also called PCB and PLC is combined version of Logic card and memory
6.What is the meaning of certification cost?
Total costs depend on your specific product or service and the licensing package.
7.Why resistance has colour code?
it has colour code because there r so many resistance in circuit and if any one will be burn then after dis-soldering we can see the resistance value easily by color code. now a day in resistance it has writen its own value on it…..
8.What is the u value?
over all heat coeffiecent
9.What are your plans for your future?
i will be good experiences engineer in a field
10. What is the Expansion of SCADA, DCS & HMI?
SCADA- Supervisory Control And Data Acquisition
DCS- Distribution Control System and
HMI – Human Machine Interface
11. Method for Testing Light Emitting Diode ( LED )?
Give forward Bias voltage to the LED’s pin by using Multi meter,if it is ok then it will glow up or remains in off state.
12. What is principal work of “O ring”?
O rings are fitted to form a leak proof joints between two mating surfaces. O ring is like a Gasket which is made by rubber to protect the leakage of gas or vapour in-between two metal products.
13. What is the difference between Relay and Contactor?
Purpose of a relay is to protect a device or a circuit. Whereas purpose of a contactor is to make and break the circuit thereby extracting the required signals from their auxiliary contacts.
14. How to make various operations by Pressing a single push button
(at least for 2 operation) ?
It is simple by using contactors and auxiliary relays to do the operation. BMS (Building Management System ) and PLC (Programmable Logic Controller) are the latest versions but comparatively expensive.
15. What is the Difference Between SCADA and BMS?
SCADA is a control and data acquisition interface software, installed on computers (often PCs) and used with industrial automation controls (PLCs). They are generally developed by automation product manufacturers, (Rockwell, Siemens, Invensys, by some independents) (often bought by larger automation industries, look at wonder ware, Citect, In-touch), and sometimes by individuals who like their own interfaces in Visual C, Delphi… Communications are carried out over specialized buses such as Modbus, Profibus, Fieldbus, Industrial Ethernet… and the sensors, drives, motor controllers are designed to exchange with the PLCs over such links.
Building Management Systems are a parallel industry; components are different, manufacturers are HVAC and lighting industrials (Carrier, Trane, Honeywell) and standards are different. They use different communication protocols (BACNET, EIB, Lon Works) and different standards. Generally, industrial standards will use more power, control higher voltages, and use smaller gauge wire than building automation.
16. How to control Temperature (Electronics way)?
We can use 1 RTD ( Resistance Temperature Detector ) for temperature detection. When temperature change, resistance also changes in RTD. This RTD input can be given to a PLC and from the output of the PLC a valve can be controlled based on RTD input. This valve can in turn control the temperature of a container by the valve ON/OFF operation.
17. What is Mechatronics Engineering?
Mechatronics engineering is the design of computer-controlled electromechanical systems. It can be viewed as ‘modern mechanical engineering design’ in the sense that the design of the mechanical system must be performed together with that of the electrical/electronic and computer control aspects that will comprise the complete system.
Some examples of mechatronic systems include: a CD or DVD player; a computer hard disc drive; a video cassette recorder (VCR); a fly-by-wire aircraft control system; and an anti-lock braking system (ABS). Each of these products is essentially mechanical in nature, but could not function without the integral design of the electrical and computer control systems that are critical to their operation.
18. Why study mechatronics engineering?
Mechatronics engineers design or select sensors and actuators, develop control algorithms and use or develop advanced functional materials for the design of mechanical systems such as chassis stabilising systems, anti-lock brakes, engine control units, disk drives, cameras, service and surgical robots and artificial hearts.
Very often mechatronics engineers are generalists rather than specialists.
Mechatronics systems are used nearly everywhere in society. They range from CD and DVD players to computer hard disks, anti-lock braking systems, and “fly-by-wire” control systems for commercial jets. Each of these products is essentially mechanical in nature, but could not function without electrical and computer control systems.
Mechatronics engineering combines mechanical engineering, electronics, control engineering, and computer science to design systems such as those listed above.
19. What are the career opportunities?
Mechatronics engineering has become an internationally recognised discipline with degree programmes offered in Japan, the United States of America, Europe and Australia. There are many opportunities for mechatronics graduates.
The desire for a high-tech, knowledge-based economy that has recently been expressed. A recent survey of our mechatronics graduates and companies employing our graduates indicated strong support for the degree. Mechatronics engineers are employed in a wide range of jobs in design, improvement, implementation and maintenance of high-tech products, services and processes in mechanical, electronic and computer-related businesses.
With the multi-disciplinary nature of mechatronics engineering it is anticipated that mechatronics engineers will have excellent opportunities and progress quickly to jobs with greater responsibilities.
