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