The following setup uses a light sensor to measure the speed and produces a digital signal. Strain gauge, LVDT and thermocouple are examples of a) Active transducers b) Passive transducers c) Analog transducers d) Primary transducers Ans : (c) 6. The transducer is of many types, and they can be classified by the following criteria. An inverse transducer … Common examples include microphones, loudspeakers, thermometers, position and pressure sensors, and antenna.Although not generally thought of as transducers, photocells, LEDs (light-emitting diodes), and even common light bulbs are transducers. What is the input of the data acquisition system (DAQ) to which a transducer is connected called? Let us consider the non-electrical quantities such as pressure, illumination of light and temperature. The change in input (temperature, pressure, etc.) Q. • Example: a digital voltmeter with resolution of 0.1V is used to measure the output of a sensor. For example, a photocell (LDR) is a passive transducer … Function of transducer is to convert A. By transduction used. Example of digital transducer is a Shaft Encoder, Limit Switch, Digital Tachometer etc. Channel. c) Digital transducer d) Pulse transducer Ans : (d) 4. Control element. The matching layer between the piezoelectric element and the tissue is designed to: These pulses are counted by the counter and final output is displayed on the numeric display. The light sensor captures the presence or absence of the light and sends logic 1 or logic 0 signal accordingly to the counter. The figure-2 depicts digital sensor operation. Transducers which require an external power source for their operation is called as a passive transducer. In digital sensors, the signal measured is directly converted into digital signal output inside the digital sensor itself. that will provide a change of 0.1V on the voltmeter is the resolution of the sensor/voltmeter system. Shaft Encoder is used to measure the angular position & velocity and its output is digital in nature. Which of the following is a digital transducer? The shape corresponding to the image created by a phased array transducer most closely corresponds to which of the following? Interface. Transducer - MCQs with answers Q1. Hence, we will get the following three active transducers depending on the non-electrical quantity that we choose. a) Strain gauge b) Encoder c) Thermistor d) LVDT Ans : (b) 5. 1. answer choices . answer choices … A transducer is an electronic device that converts energy from one form to another. • In digital systems generally , resolution may be specified as 1/ 2 N (N is the number … And this digital signal is transmitted through cable digitally. This set of Instrumentation Transducers Multiple Choice Questions & Answers (MCQs) focuses on “Analog to Digital Converters”. as a primary and secondary transducer; as a passive and active transducer; as analogue and digital transducer; as the transducer and inverse transducer; The transducer receives the measurand and gives a … Non electrical quantity into electrical signal C. Electrical signal into mechanical quantity D. All of these View Answer / … Limit Switch is the simplest example of digital transducer. Example of digital sensor: Digital Light sensor which uses rotating disc to generate output pulse with logic 0 and logic 1. Digital sensor has greater resolution and high accuracy compare to analog sensor … There are different types of digital sensors that overcome disadvantages of analog sensors. Digital Accelerometers. Reduce the acoustic impedance mismatch between the element and tissue. Electrical signal into non electrical quantity B.

Modified and converted into a digital format for processing

... Report an issue . Typical conversion speed of ADC is _____ a) Less than 1µs b) Less than 100 µs c) Less than 500 µs d) Greater than 1000 µs View Answer They produce an output signal in the form of some variation in resistance, capacitance or any other electrical parameter, which than has to be converted to an equivalent current or voltage signal. Following is not an example of transducer. Active transducer is a transducer, which converts the non-electrical quantity into an electrical quantity. In the above setup, the rotating disc is connected to the shaft of a motor and has number of transparent slots.
