Sensors & Transducers Questions and Answers<\/strong><\/h2>\n

\"Sensors<\/p>\n

1) What is instrument?<\/strong><\/span><\/h2>\n

It is a device for determining the value or magnitude of a quantity or variable.<\/p>\n

2) Add 826 <\/strong>\u00b1 <\/strong>5 to 628 <\/strong>\u00b1 <\/strong><\/span>3.<\/span><\/strong><\/h2>\n

N1 = 826 \u00b1 5 ( = \u00b1 0.605%)<\/p>\n

N2 = 628 \u00b1 3 ( = \u00b1 0.477%)<\/p>\n

Sum = 1,454 \u00b1 8 (=\u00b1 0.55%)<\/p>\n

3) Subtract 628 <\/strong>\u00b1 <\/strong>3 from 826 <\/strong>\u00b1 <\/strong>5.<\/strong><\/span><\/h2>\n

N1 = 826 \u00b1 5 ( = \u00b1 0.605%) N2 = 628 \u00b1 3 ( = \u00b1 0.477%)<\/p>\n

Difference = 198 \u00b1 8 (= \u00b1 4.04%)<\/p>\n

4) List three sources of possible errors in instruments.<\/span><\/strong><\/h2>\n
    \n
  1. Gross Error<\/li>\n
  2. Systematic<\/li>\n
  3. Random errors.<\/li>\n<\/ol>\n

    5) Define Instrumental error.<\/strong><\/span><\/h2>\n

    These are the errors inherent in measuring instrument because of their mechanical structure.<\/p>\n

    6) Define limiting error.<\/strong><\/span><\/h2>\n

    Components are guaranteed to be within a certain percentage of rated value.<\/p>\n

    Thus the\u00a0manufacturer has to specify the deviations from the nominal value of a particular quantity.<\/p>\n

    7) Define probable error.<\/strong><\/span><\/h2>\n

    It is defined as r = <\/strong>\u00b1 0.6745s where s is standard deviation.Probable error has been used in experimental work to some extent in past, but standard deviation is more convenient in statistical work.<\/p>\n

    8) Define Environmental error<\/strong><\/span><\/h2>\n

    These are due to conditions in the measuring device, including conditions in the area surrounding\u00a0the instrument, such as the effects of changes in temperature,humidity.<\/p>\n

    9) Define arithmetic mean.<\/strong><\/span><\/h2>\n

    The best approximation method will be made when the number of readings would give the best\u00a0result.<\/p>\n

    10) Define average deviation.<\/strong><\/span><\/h2>\n

    By definition, average deviation is the sum of \u00a0absolute values of the \u00a0value deviations divided by the number of reading.<\/p>\n

    11) Define units.<\/strong><\/span><\/h2>\n

    It is necessary to define a physical quantity both in kind and magnitude in order to use this\u00a0information for further proceedings. The standard measure of each kind of physical quantity is named as the unit.<\/p>\n

    12) Define Standards<\/strong><\/span><\/h2>\n

    The physical embodiment of a unit of measurement is a standard.<\/p>\n

    For example,the fundamental\u00a0unit of mass in the international system is the kilogram and defined as the mass of a cubic decimeter of water at its temperature of maximum density of 4\u00b0c.<\/p>\n

    13) Draw the functional block diagram of a measurement system.<\/strong><\/span><\/h2>\n

    \"block-diagram-of-a-measurement-system\"<\/p>\n

    14) Mention the purpose of the measurement.<\/strong><\/span><\/h2>\n
