Homework Answers
Answer
OPTION 1 : It is correct as : PROPORTIONAL BAND = 100 / GAIN
OPTION 2 is incorrect as Gain is not a control mode but a control parameter
OPTION 3 is incorrect as : PROPORTIONAL BAND = 100 / GAIN , so they cannot be independently adjusted
OPTION 4 is incorrect as Gain is generally reported as dimensionless .
Add Answer to:
9. Gain and proportional bands are: 1) Reciprocally related 2) Two different control modes 3) Adjusted...
