Measurement is an important subsystem in any major system, whether it may be a mechanical system or an electronic system. PPT – ECE5320 - Mechatronics Assignment 1: Literature Survey on Sensors and Actuators Topic: DC Motors (Actuators) PowerPoint presentation | free to view - id: 43a028-YzM5Y. Sensors need frequent calibration for many reasons. Sensors and transducers Measurement is an important subsystem of a mechatronics system.

For example grocery shop automatic doors: Step 1: The sensor will identify the person if anyone is standing in front of the door and it will create signal. Sensors are considered as transducers that convert input energy of one form into output energy of another form. Flow Instruments – Selection, Principle & Application. Tag: mechatronics sensors and transducers ppt. Definitions: Transducer and sensors • Transducer – a device that converts a primary form of energy in to a corresponding signal with a different energy form Primary Energy Forms: mechanical, thermal, electromagnetic, optical, chemical, etc. 10. 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. For digital sensors, it is related to number of bits used For analog sensors, it is limited by low-level electrical noise Sensitivity 12. Sensors and transducers; Displacement and position sensors ; Displacement, position and proximity sensors; Velocity, motion, force and pressure sensors ; Temperature and light sensors; Signal Conditioning Devices; Protection, conversion and pulse width modulation Drift should be as minimum as possible.

Based on thirty years of extensive work in industry and teaching, this book provides an overview of the sensors and sensor systems required and applied in mechatronics with an emphasis on understanding the physical principles and possible configurations of sensors rather than simply a discussion of particular types of sensors.

The nature of output required from the sensor whether the digital or analog has to be considered while selecting a sensor. Module 1-Introduction Sensors and Transducers: Static and dynamic Characteristics of Sensor, Potentiometers – LVDT- Capacitance sensors – Strain gauges – Eddy current sensor – Hall effect sensor – Temperature sensors – Light sensors. Get the plugin now No transducer is sensitive to one physical energy only Consider a small volume dV in which transducer is placed The energy content dW in this volume contains the summation of all possible energies Ii - intensive quantity (can carry power, e.g., force, pressure, voltage) If you continue browsing the site, you agree to the use of cookies on this website. Sensors and transducers . Sensors for Mechatronics, Second Edition, offers an overview of the sensors and sensor systems required and applied in mechatronics. Classify sensors in various categories. Advanced Mechatronics, Georgia Tech fME8843 Ultrasonic transducer (piezoelectric transducer) is device that converts electrical energy into ultrasound Upon receiving sound echo (pressure wave) back from surface, ultrasound transducer will turn sound waves into electrical energy which can be …
