Linearity of transducer is ___________(a) Closeness of the transducer’s calibration curve to a special curved line within a given percentage of full scale output(b) Closeness of the transducer’s calibration curve to a special straight line within a given percentage of full scale output(c) Closeness of the transducer’s calibration curve to a special straight line within a given percentage of half scale output(d) Closeness of the transducer’s calibration curve to a special curved within a given percentage of half scale outputThe question was asked during an interview.This intriguing question originated from Classification of Transducers topic in portion Physiological Transducers of Biomedical Instrumentation

Answer» CORRECT option is (B) Closeness of the transducer’s calibration curve to a special straight line within a GIVEN percentage of full scale output

The best explanation: Linearity of transducer is closeness of the transducer’s calibration curve to a special straight line within a given percentage of full scale output. Basically, it reflects that the output is in some way proportional to the input. A LINEAR sensor produces an output value which is directly proportional to the input.
