1 Answer

Answer :

Transducer - It converts one form of signal into another form.

A transducer is a device that is used to convert a physical quantity into its corresponding electrical signal.

Selection factors

• Operating Principle : The transducers are selected on the basis of operating principle it may be resistive, inductive, capacitive, optical etc.

• Operating range : The range of transducer should be appropriate for measurement to get a good resolution.

• Accuracy : The accuracy should be as high as possible or as per the measurement.

• Range : The transducer can give good result within its specified range, so select transducer as per the operating range.

• Sensitivity : The transducer should be more sensitive to produce the output or sensitivity should be as per requirement.

• Loading effect : The transducer’s input impedance should be high and output impedance should be low to avoid loading effect.

• Errors : The error produced by the transducer should be low as possible.

• Environmental compatibility : The transducer should maintain input and output characteristic for the selected environmental condition.
