Data Managers & Data Loggers

Data Managers & Data Loggers

Data managers and data loggers are dedicated systems for organizing, visualizing, and safeguarding process values. They collect measured signals, present them clearly on a local display, log values securely, and support limit monitoring and analysis so deviations are captured as actionable events. Using common communication protocols, measured and calculated values can be shared with higher-level systems and used to interconnect modular plant skids and unit operations.

In practice, these devices replace paper charts and ad hoc PC logging with purpose-built, industrial-grade recording and monitoring. Endress+Hauser’s portfolio includes paperless data managers for recording, visualization, and monitoring, as well as simpler data loggers focused on display and storage of measured values. Because these systems operate without pens and paper, they reduce wear-related maintenance and simplify long-term retention of operating history.

Integration and accessibility are central strengths. Recorded information can be stored internally or on exchangeable media and, when required, transmitted to superior systems for long-term archiving and rapid retrieval. Options such as integrated web-server functionality enable remote access to device operation and visualization, reducing routine walkdowns and supporting faster troubleshooting. Connectivity can also extend to common fieldbus environments to streamline integration into diverse automation topologies.

Typical applications include continuous compliance and quality logging, batch documentation, utility and wastewater reporting, skid performance trending, alarm/event correlation, and validation support for critical steps such as CIP/SIP. When process incidents occur, time-aligned trends, alarms, and calculated channels accelerate root-cause analysis and help distinguish true process upsets from instrumentation or utility disturbances.

Selection and design work best when the logging strategy is defined up front: required inputs, scan rates, time synchronization, alarm philosophy, report needs, retention periods, and interface points to SCADA/DCS/historians. For regulated environments, capabilities such as fully traceable calibration documentation and tamper-proof data storage aligned with FDA 21 CFR Part 11 can be applied where appropriate to strengthen audit readiness.
