What is the primary purpose of an event recorder?

The primary purpose of an event recorder is to document specific events for future analysis. Event recorders play a crucial role in process control and instrumentation by capturing critical data points related to operational events, alarms, and system changes. This documentation allows operators and engineers to revisit situations that may require investigation, such as system failures, anomalies, or any deviations from normal operating conditions. By reviewing the recorded events, they can conduct detailed analyses to understand the cause and effect relationships, which ultimately aids in improving system performance and reliability.

While efficiency analysis, flow regulation, and temperature measurement are important aspects of process control, they are generally handled by other specialized instruments and systems. Event recorders specifically focus on capturing significant occurrences in a manner that supports further scrutiny and continuous improvement of the overall process.
