Difference Between Transducer and Sensor

What are Transducers?

Transducers are elements that convert the input physical variable into a usable form. In most cases, the output signal is in the form of an electrical signal. The advantages of an electrical signal is that inertial and frictional effects are absent as in transducers with mechanical output, amplification can be achieved in a relatively easier manner and distant indication and recording is also facilitated. There is a wide range of transducers classified based on the operating principle, output signal, etc. Various types of transducers are discussed as follows....

Parts of Transducer

Working Principles of Transducers

The basic principle of working of transducers is to convert one form of energy to another. These devices take input of physical quantities such as pressure, temperature, light, or sound, and convert it into a corresponding output signal for measurement and control purposes. A brief explanation of different principles involved behind working of transducers is discussed as under....
