a) Precession View Answer, 10. Uploaded By curlymusk97. c) Hall effect sensor A transducer that converts measurand into the form of pulse is called a) Active transducer b) Analog transducer c) Digital transducer d) Pulse transducer Ans : (d) 4. The transduction medium may be resistive, inductive or capacitive depends on the conversion process that how input transducer converts the input signal into resistance, inductance and capacitancerespectively. b) Accuracy In general, the process of transduction involves the conversion of one form of energy into another form. here is complete set of 1000+ Multiple Choice Questions and Answers, Prev - Mechatronics Questions and Answers – Transducers – Static Characteristics, Next - Mechatronics Questions and Answers – Displacement Sensors, Mechatronics Questions and Answers – Transducers – Static Characteristics, Mechatronics Questions and Answers – Displacement Sensors, Aircraft Maintenance Questions and Answers, Geotechnical Engineering II Questions and Answers, Engineering Metrology Questions and Answers, Mechatronics Engineering Questions and Answers, Electrical Measurements Questions and Answers, Dynamic Programming Problems and Solutions, Instrumentation Transducers Questions and Answers, Instrumentation Transducers Questions and Answers – Measurement and Callibration, Electrical Measurements Questions and Answers – Classification of Transducers, Mechatronics Questions and Answers – Measurement Systems, Instrumentation Transducers Questions and Answers – Filtering and Dynamic Compensation, Instrumentation Transducers Questions and Answers – Inverse Transducers, Biomedical Instrumentation Questions and Answers – Classification of Transducers, Instrumentation Transducers Questions and Answers – Pressure Measurement, Instrumentation Transducers Questions and Answers – Measurement of Errors, Instrumentation Transducers Questions and Answers – Digital Transducers, Instrumentation Transducers Questions and Answers – Photo Electric Transducers. A primary transducer is used to change the physical quantity to the mechanical signal whereas a secondary transducer is used to convert a mechanical signal to an electrical signal. For example, for a transducer used for temperature measurement, sensitivity will be expressed in mV/’ C. A high sensitivity is always desirable for a given transducer. 8. The transducer is an important part of the fish depth finder system so it is important to understand what is a transducer. In reality, however, anything that converts energy can be considered a transducer. Ungraded . ON is logic 1 and OFF is logic 0. A transducer is a device which, when actuated transforms energy from one form to another. View Answer, 3. Passive transducer requires external power supply. Amplify the input signal. Which one of the following … View Answer, 13. a)Loudspeaker. A foam like material, having a resistance that varies depending on how much it is compressed, is known as are examples of transducers. One example is a speaker, which converts an amplifier's electrical energy into sound waves or mechanical energy. Example of transducers are: thermocouple; microphones ; The transducer consists of a sensor and signals conditioning circuits and finds application in communication systems to convert the electricity to electromagnetic waves. Operating range : The range of transducer should be appropriate for measurement to get a good resolution. Which among the following is not a dynamic characteristic? Strain Gauge is a passive transducer that converts a mechanical elongation or displacement produced due to a force into its corresponding change in resistance R, inductance L, or capacitance C. A strain gauge is basically used to measure the strain in a work piece. It can perform in an industrial environment. As shown in the figure, passive transducer will produce variation in the passive element in accordance with the variation in the non-electrical input quantity (or signal). b) triode 13. Although not generally thought of as transducers, photocells, LEDs (light-emitting diodes), and even common light bulbs are transducers. b) Thermoelectric transducer A thermocouple is used to generate a voltage corresponding to the heat that is generated at the junction of two dissimilar metals. Selection of Transducer. The use of these elements and devices is not limited to measuring systems.
