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 …

Zeroth Law Of Thermodynamics

Thermal Equilibrium and Zeroth Law Of Thermodynamics Explained With 5 Real-Life Examples

Thermal Equilibrium: By the touch of our hand, we can roughly determine which is the hottest or coldest object. The hotness or coldness of an object was called temperature. If two objects give the same feeling of being equally hot (or cold), they are said to have the same temperature, and objects are said to …
