Question

What is the relation between overall magnification and pneumatic sensitivity in pneumatic comparators?

(a) Independent of each other

(b) Overall magnification is directly dependent on the square of pneumatic sensitivity

(c) Overall magnification is inversely proportional to the pneumatic sensitivity

(d) Overall magnification is directly dependent on the pneumatic sensitivity

I got this question in quiz.

The above asked question is from Pneumatic Comparators topic in division Comparators of Engineering Metrology

Answer 1

Right option is (d) Overall magnification is directly dependent on the pneumatic sensitivity

Explanation: Overall magnification is the rate of change of linear movement of the pointer to the change in the dimension which produces it and represented as dR/dL. It is directly proportional to the pneumatic sensitivity.
