Answer :

* 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.
