Sensor and Transducer

Question 1

Explain Sensor and Transducer

Answer 1

Sensor –> This is an element that senses a variation in input energy to produce a variation in same form of energy.

Transducer –> This device converts and strengthens a non electric signal into usually an electric signal.

Question 2

Explain Active and Passive Transducers

Answer 2

Active –> For this transducer to work, no external energy source is applied. Works on the principle of energy conversion.

Passive –> No External energy source is applied. Works on the principle of control of already provided voltage.

Question 3

What is a Resistive Transducer

Answer 3

It’s a type of transducer that changes it’s resistance / resistive element is sensitive towards the physical variable that we need to measure.

Question 4

What is an Inductive Transducer

Answer 4

It’s a type of transducer that changes it’s Inductance / inductive element is sensitive towards the physical variable that we need to measure.

Question 5

What is an Capacitive Transducer

Answer 5

It’s a type of transducer that changes it’s Capacitance / capacitive element is sensitive towards the physical variable that we need to measure.
