Units of measurement

In measuring a quantity, we always compare it with some established reference standard. Such standard is called a unit of a quantity. Measurement implies a comparison with a standard value. To say that a rope is 30 m long is to say that is 30 times as long as an object whose length has been defined to be 1 meter.


Fundamental Units

Basic units of mass (M), Length (L), time (T) are known as fundamental units. These are also known as the primary fundamental unit.

Physical variables and transducer

unit 3 Physical Variables and transducers  Sensor Sensors are electrical devices that have the capability of sensing different physical variables. The sensor may be classified on different bases one of them is a physical quantity. Hence on the basis of a physical quantity or physical vibration involved the sensors are classified as: Resistive sensor  The input being measured is transformed into a change in resistance. examples: potentiometer, resistance thermometer, strain gauge, etc. Inductive sensor The input being measured is transformed into a change in resistance. example LVDT. Capacitive Sensor The input being measured is transformed into a change in capacitance. example: capacitive Displacement sensor. On the basis of power supply required: Active Sensor Active sensors are those which do not require an external power supply.  example: thermo-couple Passive Sensor Passive Sensors are those which require a power supply. example: Potentiometer. Physical variables and ...
