Transducers- Introduction, Classification and Application

The quantity under measurement in an instrumentation system is called ‘Measurand’ or ‘Information’. The primary sensing elements, called ‘Sensors’, sense the condition, state, or value of the measurand and convert the energy to an output of some other type of energy. The sensors are called ‘Primary Trunsducers’ or ‘Detectors’. Sometimes a ‘Secondary Transducer’ may be …

Semiconductor- Introduction, Types and Comparison

Conductors, semiconductors, and insulators are three types of materials. Semiconductors are those materials whose conductivity lies between that of conductors and insulators. Most electronic devices are based on semiconductors. At absolute zero(0°K) temperature, the semiconductors behave as insulators. As temperature increases, the conductivity increases. In the old days, only vacuum tubes were used. But nowadays …
