Control some variable to some particular value, e.g., a central heating system where, the temperature is controlled to a particular value, 2. This might, for, example, be a pointer moving across a scale or a digital readout, Control system, A control system can be thought of as a system which can be used to:, 1. A display system displays the output from the signal conditioner. ![]() and might be fed through an amplifier to obtain a bigger signal., 3. Thus, for example, the output from a thermocouple is a rather, small e.m.f. A signal conditioner takes the signal from the sensor and manipulates it into a, condition which is suitable either for display or, in the case of a control system, for use, to exercise control. For example, a thermocouple is a temperature sensor., The input to the sensor is a temperature and the output is an e.m.f., which is related to, the temperature value., 2. A sensor responds to the quantity being measured by giving as its output a signal, which is related to the quantity. Mechatronics (15ME54T), Elements of Measurement system,, 1. ![]() It has as its input the quantity being measured and its output the value, of that quantity., For example, a temperature measurement system, i.e., a thermometer, has an input of, temperature and an output of a number on a scale,, Sandur Polytechnic,, ,, Department of Mechanical Engineering A measurement system can be thought of as a box which is used for making, measurements. A Motor can be considered as a system to have an input Electric power P and an, output of Rotation RPM.,, 3. A spring can be considered as a system to have an input of a force F and an output of, an extension x., 2. Such, models involve drawing block diagrams to represent systems., Definition: A system can be thought of as a box or block diagram which has an input, and an output and where we are concerned not with what goes on inside the box but with only, the relationship between the output and the input., Example:, 1. ![]() Mechatronics (15ME54T), The basic elements of a mechatronic system,, System, In designing mechatronic systems, one of the steps involved is the creation of a model, of the system so that predictions can be made regarding its behaviour when inputs occur. It makes the system cheaper,, Sandur Polytechnic,, ,, Department of Mechanical Engineering ![]() Mechatronics technology, helps on lowering development costs, reduce risk, produce high quality products., In the design of cars, robots, machine tools, washing machines, cameras and very, many other machines, such an integrated and interdisciplinary approach to engineering design, is increasingly being adopted., Mechatronics brings together areas of technology involving sensors and measurement, systems, drive and actuation systems, and microprocessor., 1. Therefore, Mechatronics is also, called as electromechanical systems or control automotive Engg. As situation became competitive, it, was necessary to combine electronics & mechanical Engg. This results in much greater flexibility, easy redesign and reprogramming, and the ability to carry out automated data collection and reporting., Definition of Mechatronics, Mechatronics can be defined as an interdisciplinary approach to engineering design, through an integration of mechanical engineering, electrical engineering, computer, technology, electronics and control engineering, Examples:, Truck smart suspension system-Its suspension adjusts to uneven loading conditions, camera, robots, auto guided vehicle, fax machines, printers, washers, dryers etc., Importance, The manufacturing industries totally depend on integration of, computer science, electronics technologies for better products and processes. The word now has a, wider meaning, being used to describe a philosophy in engineering technology in which there, is a coordinated, and concurrently developed, integration of mechanical engineering with, electronics and intelligent computer control in the design and manufacture of products and, processes., As a result, Mechatronic products have many mechanical functions replaced with, electronic ones. Mechatronics (15ME54T),, UNIT 1, MECHATRONICS, SENSORS AND TRANSDUCERS, Introduction to Mechatronics Systems - Measurement Systems - Control Systems –Sensors and, Transducers - Performance Terminology - Sensors for-Displacement, Velocity, Force, Fluid, Pressure, Liquid Flow, Liquid Level, Temperature, Light Sensors, Selection of Sensors., Course outcome: Discuss the importance of mechatronics systems and know the, usage of Sensors and Transducers for automation applications, Introduction to Mechatronics Systems, The term Mechatronics was ‘invented’ by a Japanese engineer in 1969, as a, combination of ‘mecha’ from mechanisms and ‘tronics’ from electronics.
