February 4, 2017 The words sensors and transducers are widely used in association with measurement systems. But a transducer is a more definite concept. Multiple Choice Questions on Sensors & Transducers. This is an accelerometer for measurement of accelerometer for measurement of acceleration in the range ± 4g. So it is called primary transducer. It measures temperature, pressure, displacement, force, vibrations, etc. The gauge factor is unit resistance change per unit strain, which is due to three factors as revealed by the above equation.

The sensor is a device, that senses a physical quantity and converts it into an analogue quantity which can be measured electrically such as voltage, capacitance, inductance and ohmic resistance.The output needs to be operated, interfaced & regulated by the system designer. By definition, average deviation is the sum of  absolute values of the  value deviations divided by the number of reading.

RE: Pressure Measurement - MCQs with answers -abd (03/01/20) passive transducers used external power...active not RE: Pressure Measurement - MCQs with answers -Anonymous (04/30/19) In these transducers self-inductance or the mutual of a couple of coils is changed when the quantity to be measured is varied. Well-designed resistance thermometers have excellent stability. A device which converts an electrical quantity into a non-electrical quantity. Frequency response is thus defined as the steady – state output of a transducer when it is excited with sinusoidal input. Save my name, email, and website in this browser for the next time I comment. In this case output deviates from the correct value by a constant factor over the entire range of transducer. Another common version of the variable reluctance principle. Electrical device can act as a secondary transducer. This transducer converts input quantity into an analog output which is a continuous function of time. It is used avoid the fluctuation, we need dynamic compensation circuits for the hotwire anemometer. ANSWER: C. Thermography . Introduction to Sensors and Transducers Differences. Shielded against the effect of external electric stray fields. The sensor is a device, that senses a physical quantity and converts it into an analogue quantity which can be measured electrically such as voltage, capacitance, inductance and ohmic resistance.The output needs to be operated, interfaced & regulated by the system designer. A. Cardiovascular system B. Sanfoundry. Commonly used for measurement of level, density, weight. Since these errors remain even after the systematic errors are taken care of,they are called residual errors. This minimum value of the input is defined as the threshold of the transducer. D) Transient, A) Photo diode Since the force required accelerating a mass is proportional to the acceleration.. To detect motion on both sides of zero, a fairly involved phase- sensitive demodulator would be required. Iron , nickel, 68 permalloy and ferroxcube ect . This increment is defined as the resolution. The number of tracks must be increased and the length of each coded should be reduced, which would require fine brushes. In general anemometers are devices used for measurement of velocity of flow. Click on the below button to launch the Quiz. (A) Have to be machined and fit with other mating components ... Answer A. MCQ No - 2. a) Noise figure of 0 db. An ideal amplifier has. The following are the major functional physiological systems of the body except? Which consists, as already mentioned above, and of the sensor as well. It is a ratio of stress and strain, dR/R / dl/l. C) Probable error 1. The primary is excited with alternating current. MCQ No - 1.

Save my name, email, and website in this browser for the next time I comment. The permeability can increase or decrease depending upon the material, type of stress , and the magnetic flux density in the sample. It is necessary to define a physical quantity both in kind and magnitude in order to use this information for further proceedings. It is a device for determining the value or magnitude of a quantity or variable. Scale factor is inverse of sensitivity The amplitude of this output voltage varies with the mutual inductance between the two coils and this varies with the angle of rotation. Fiber optic cable consists of outer core and inner cladding. There are errors due to self-heating and thermoelectric effect of theresistive element and connecting leads (dissimilar metal junctions).
