What does an Analyzer do?

• A. Provides an analysis of a sample from the process.
• B. Converts current to pressure.
• C. National Institute of Standards and Technology paper trail.
• D. Terminals 1-3.

Answer: (A)

The job of an Analyzer is to determine what is in a sample taken from the process. It analyzes the composition or quality of that sample and provides measured values—such as concentrations of components, impurities, moisture, or other key parameters—that feed into control systems or quality checks. This real-time or near-real-time data lets operators adjust the process, optimize performance, and ensure products meet specifications. Analyzers use techniques like spectroscopy, electrochemical sensing, chromatography, or other analytical methods depending on what needs to be measured.

Converting current to pressure describes a transducer or transmitter function, not analysis. A National Institute of Standards and Technology paper trail isn’t a device function, and terminals refer to wiring connections, not analyzing samples.
