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. Our focus will be on nonlinear sensors. Linearity: Sensor’s curve should linear. Accuracy indicates the closeness of the measured value with the actual/true value and is usually expressed in percentage of full scale reading. ( Log Out /  There are different kinds of sensors available and transducers to choose from such as analog, digital, input and output. Change ), You are commenting using your Twitter account. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. Successive readings may be close to each other, but far from the true value. The signal processor performs filtering, amplification or other signal conditioning on the transducer output. Change ), You are commenting using your Facebook account. The sensor output signals are not suitable to be processed directly hence an input signal conditioning stage modifies the signals to desired state. a rotary encoder. Sensors are also referred to as transducers. 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. Drift should be as minimum as possible. A fundamental part of many Mechatronics systems is a measurement system composed of three basic parts as illustrated in the figure below.

The secondary transducer converts the output of primary transducer into electrical signal. Clipping is a handy way to collect important slides you want to go back to later. D. All of The … 2) What is meant by system in mechatronics? Zero drift is defined as the change in output (∆y) without any corresponding change in input. Suitable for practicing engineers and those wanting to learn more about sensors in mechatronics; Whatever we discussed till now is all about static characteristics of a transducer. 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. The primary function of the sensor is to sense the physical changes, whereas the transducer converts the physical quantities into an electrical signal. 2. ( Log Out /  10. Now let us consider some dynamic performance characteristics of a transducer. Prof. @ Dr. Akhilesh Das Gupta Institute of Technology and Management, New Delhi. Range defines the maximum and minimum values of the inputs or the outputs for which the instrument is recommended to use. Identify sensors for various mechatronics applications. For example, an instrument with input range -10 °C to +150 °C has a span of 150-(-10) = 160 °C. INTRODUCTION Basic Elements in Mechatronics system • The actuators produce motion. Its located on the spindle so that it can monitor the position of the throttle . S Bharadwaj Reddy December 31, 2016 August 14, 2019. There are many types of sensors; Thermal, Mechanical, Electrical, Chemical, Optical, Acoustic, Resistive, Capacitive, Inductive, etc. (Course Code:18ME36B). Introduction to Sensors & Actuators. Signal filtering, amplification and analog to digital conversion are the most common input conditioning operations. 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. 3. Mechatronics design engineer must know the capability and shortcoming of a transducer or measurement system to properly assess its performance. Precision means repetition of successive readings, but it does not guarantees accuracy. Differentiate between sensors and transducers. The transducers are classified as follows-, On the basis of the method used for transduction –. An output signal conditioning stage converts this control signal into a convenient signal for actuator operation and display units. ( Log Out /  The light sensors enables a robot to detect light . These are a number of performance related parameters of a transducer or measurement system. The type of transducer I / p or o / p used depends on the type of signal that is sensed or regulated. For example, a piezo-electric crystal transducer, being an active transducer, converts pressure into e.m.f. MECHATRONICS, SENSOR AND TRANSDUCERS (2 MARK QUESTIONS) 1) Define mechatronics? Following are static characteristics of a measurement system. 10 µV/°C in case of a voltmeter affected by ambient temperature change. Distinguish between position sensors and light sensors . The controller generates a control signal to achieve a desire level of output.

Introduction A sensor is defined as a device that produces an output signal for the purpose of sensing of a physical phenomenon. They are self-generating transducers. capacitive sensors proximity switches . A digital transducer converts the input physical quantity into digital form, i.e. Response Time. Sensors need frequent calibration for many reasons. Static characteristics of a transducer are those characteristics when the output signal is in the steady state in response to an input. | download | B–OK. Measurement system comprises of sensors, transducers and signal processing devices. 10 AWESOME GADGETS EVERY STUDENT SHOULD HAVE : 1.
