What type of recorder incorporates a bourdon tube?

The correct answer involves understanding the function and design of specific types of recorders within the context of power engineering. A bourdon tube is a mechanical device used to measure pressure. It works by converting the pressure exerted on it into a movement that can be recorded.

The circular chart recorder, which is the correct choice, utilizes the principles of the bourdon tube to produce a continuous graphical representation of pressure over time on a circular chart. The pressure within the system causes the bourdon tube to flex, and this movement is then translated into a trace on the chart, providing a real-time record of the system’s pressure variation.

In contrast, an analog chart recorder typically utilizes different mechanisms to convert various types of measurements into visual data. A digital multimeter measures electrical parameters like voltage, current, and resistance but does not record data on a chart and, therefore, does not incorporate a bourdon tube. A strip chart recorder, meanwhile, is designed for various types of measurements and often employs different recording technologies or systems rather than solely relying on mechanical pressure measurement such as a bourdon tube.

Understanding these distinctions clarifies why the circular chart recorder is the most appropriate answer, as it directly employs the working principles of a bourdon tube in its operation and
