Question

Which of the following sensor is not a part of the fermenter?

(a) On-line

(b) In-line

(c) Off-line

(d) Out-line

This question was addressed to me in my homework.

I need to ask this question from Instrumentation and Control topic in chapter Instrumentation and Control of Fermentation Technology

Answer 1

The correct answer is (c) Off-line

The best I can explain: Offline sensors are the sensors that are not an integral part of the fermenter. The measured value must be entered for data collection. The on-line and in-line sensors are the integral parts of the fermenter.
