Gas Heat ESCO Practice Exam

How much current does a typical flame sensor produce?

1. 1-30 microamps

2. 30-60 microamps

3. 60-90 microamps

4. 90-120 microamps

The correct answer is: 1-30 microamps

Flame sensors are typically designed to produce a small electrical current when exposed to a flame. This current is measured in microamps (µA) and can range from 1-30 microamps. Option A is the most accurate answer, as it falls within the typical range for a flame sensor. Options B-D are incorrect because they either exceed or fall short of the expected range, making them less likely to be the correct answer. It is important to understand the expected range for a flame sensor in order to accurately troubleshoot and maintain the proper functioning of this component.
