• Conditioning and interfacing circuits provide connection between the control circuits and the input/output devices. Mechatronics: Electronics in Products and Processes identifies the concepts which underpin the mechatronic approach to engineering design and brings together its principle components - sensors and transducers, embedded microprocessors, actuators and drives - to explore their interrelationships. 10 AWESOME GADGETS EVERY STUDENT SHOULD HAVE : 1. • The sensors detects the state of the system parameters, inputs and outputs. This usually involves digital to analog conversion and amplification. a rotary encoder. Usually the offset is specified in relation with the corresponding influence factor e.g. The transducers are classified as follows-, On the basis of the method used for transduction –. Sensors are also referred to as transducers. The signal processor performs filtering, amplification or other signal conditioning on the transducer output. Identify sensors for various mechatronics applications. ( Log Out / Cost: Cost of the sensor should be low. 1. Prof. @ Dr. Akhilesh Das Gupta Institute of Technology and Management, New Delhi. T… Passive transducers are defined as those transducers that require external or auxiliary power supply for their operation of conversion of physical quantity into electrical signal. Static characteristics refer to the characteristics of the system when the input is either held constant or varying very slowly. Find books The secondary transducer converts the output of primary transducer into electrical signal. For example, an instrument with input range -10 °C to +150 °C has a span of 150-(-10) = 160 °C. Mechatronics is a complete integration of electronic system, You can change your ad preferences anytime. They are the resistive type of transducers and the output voltage is proportional to the displacement and is given by: e o = ( x i /x i. At the end of the chapter student should be able to… Define sensors and transducers. 11. Even though real sensors and transducers can behave quite differently in practice, when developing a mechatronic system we should use the ideal behavior as a reference for the design speci cations. If you continue browsing the site, you agree to the use of cookies on this website. The sensor itself is the major component of the sensor, whereas the sensor and the signal conditioning are the major elements of the sensor. sensors and transducers. Drift should be as minimum as possible. Rise Time. Linearity: Sensor’s curve should linear. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. A position sensor is used to monitor the position of the throttle in an IC engine. Our focus will be on nonlinear sensors. Regtien (Auth.) The primary disciplines important in design of Mechatronics systems include mechanics, electronics, controls and computer engineering. A thermocouple is a transducer that converts temperature to a small voltage; the amplifier increases the magnitude of the voltage; the ADC (Analog to Digital Converter) is a device that changes the analog signal to a coded digital signal and the LEDs (Light Emitting Diodes) display the value of the temperature. Mechatronics is a multidisciplinary field combining Mechanical, Electronic, Computer, and other Engineering fields to develop intelligent processes and products. Introduction A sensor is defined as a device that produces an output signal for the purpose of sensing of a physical phenomenon. 2) What is meant by system in mechatronics? In this type of classification, the transducers are classified on the basis of principle of transduction, viz. The controller generates a control signal to achieve a desire level of output. The following are the key differences between the sensor and transducer. Response Time. MECHATRONICS,SENSORS AND TRANSDUCERS Mind Map by ultimate_saravan, updated more than 1 year ago More Less Created by ultimate_saravan over 5 years ago 29 3 0 Description. Sensors generate a proportional electrical signal (voltage, current etc) to the measured output. Successive readings may be close to each other, but far from the true value. 3 ME591 Mechatronics Thermal Sensors Thermometer measures absolute temperature … Mind Map on MECHATRONICS,SENSORS AND TRANSDUCERS, created by ultimate_saravan on … Sensors for Mechatronics | P.P.L. Looks like you’ve clipped this slide to already. The following main dynamic characteristic(s) is usually considered in Mechatronics application of sensors. Sensors for Mechatronics, Second Edition, offers an overview of the sensors and sensor systems required and applied in mechatronics. resistive, inductive, capacitive and so forth. Transducers or measurement systemsare not perfect systems. A fundamental part of many Mechatronics systems is a measurement system composed of three basic parts as illustrated in the figure below. when an electric charge or voltage is applied to the surface of piezo-electric crystals, the dimensions of the crystal change due to deformation. Introduction to Sensors & Actuators. The use of these elements and devices is not limited to measuring systems. The term Mechatronics is used to denote a rapidly developing interdisciplinary field of engineering dealing with the design of products whose function relies on the integration of mechanical and electronic components coordinated by a control architecture. Its main function is to collect the information on system status and to feed it to the micro-processor(s) for controlling the whole system. Definition – Mechatronics is synergetic integrartion of mechanical, electronics, controls and information technologies to obtain the best solution to a given technological problem. They are externally powered transducers, for example, a potentiometer. Now let us consider some dynamic performance characteristics of a transducer. A transducer is a device which converts the physical quantities into electrical signals. Change ), Example of Measurement system : Digital Thermometer, Static characteristics of measurement systems. These parameters are called as sensor … analog sensors and transducers; signal-conditioning devices; motion transducers; potentiometer; rotary potentiometers; displacement and performance rating; performance considerations of rotary potentiometers; optical potentiometer; optical potentiometer formulae; variable-inductance transducers; mutual-induction transducers Measurement is an important subsystem in any major system, whether it may be a mechanical system or an electronic system. ( Log Out / Hence, it should be easy to calibrate. The smallest change in a measured value that the instrument can detect is called the resolution of the instrument. ( Log Out / The sensor output signals are not suitable to be processed directly hence an input signal conditioning stage modifies the signals to desired state. See our User Agreement and Privacy Policy. Precision is the degree to which an instrument will repeat the same measurement over a period of time. Mechatronics design engineer must know the capability and shortcoming of a transducer or measurement system to properly assess its performance. C. Time Constant. • Final Examination – There will be a closed-book, closed-note, final exam Distinguish between position sensors and light sensors .

For example, for a temperature measuring instrument the input range may be 100-500 °C and the output range may be 4-20 mA. They are self-generating transducers. Hysteresis is the phenomenon in which the value of a physical property lags behind of changes in the effect causing it. The following figure shows an example of measurement system. Flow Instruments – Selection, Principle & Application. JSS Academy of Technical Education, Bangalore-560060 MECHATRONICS, SENSOR AND TRANSDUCERS (2 MARK QUESTIONS) 1) Define mechatronics? Based on thirty years of extensive work in industry and teaching, this book provides an overview of the sensors and sensor systems require… Mechatronics brings together the areas of technology involving sensors and measurement system, drive and actuation system, analysis of behavior of the system, control system and microprocessor system. 3. Sensors are the feedback elements which help sense the state of the controlled output. CHAPTER 1 MECHATRONICS, SENSORS AND TRANSDUCERS Introduction to Mechatronics systems Mechatronics is integration of mechanical engineering with electronics engineering and computer control in design and manufacturing of products and processes. Department of Mechanical Engineering Accuracy indicates the closeness of the measured value with the actual/true value and is usually expressed in percentage of full scale reading. A.
