Electronic Measurements & Instrumentation [EMI] Unit-I Basics of Measurements : 1) The measurement of a given parameter or quality is the act or result of a quantities comparison between a predefined standard and an unknown quantity to be Measured. 2) The major problem with any measuring instrument is ERROR. 3) The measuring instrument may be defined as a device for determining the Value or Magnitude of a Quantity or Variable. 4) An electronic instrument is the one which is based on Electric or Electrical principles for its measurement functions. The measurement of any Electronic or Electrical quantity or variable is termed as an Electric Measurement. 5) For any measurement, a well-defined set of Standards and Calibration Units is essential. 6) The Physical, Chemical, Electrical Quantity, Property Process, Variable or a Condition to be measured is referred as “ Measurand” 7) The various Physical Measurands are Pressure, Level Force, Strain, Velocity etc., 8) While the Electrical Measurands are Voltage, Current, Power and Frequency. Fundamental Elements of an Instrument : The Elements present are a. Primary Sensing Element. b. Data Conditioning Element. c. Data Presentation Element.
