What Is the Difference Between the Closed-Loop and Opened-Loop Methods in Power Sensors?
Frequently Asked Questions (FAQs)
Summary
In power sensors, the closed-loop method uses a bridge feedback of substituted DC power while the opened-loop method depends on the sensitivity or linearity of the sensing element.Question
What Is the Difference Between the Closed-Loop and Opened-Loop Methods in Power Sensors?Answer
In power sensors, the closed-loop method uses a bridge feedback of substituted DC power while the opened-loop method depends on the sensitivity or linearity of the sensing element.Only thermistor power measurements use the closed-loop method while all other thermocouple and diode type of sensing uses the opened-loop method.
