Industrial Recorder and Data Logger Operating Guide
Industrial recorders and data loggers provide permanent records of process parameters for quality assurance, regulatory compliance, and troubleshooting.
I. Types
- Strip Chart Recorders: Continuous pen recording on moving paper. Simple, reliable, and provide immediate visual trends.
- Circular Chart Recorders: Record on rotating circular charts. Common for applications requiring daily or weekly record changes.
- Paperless Recorders: Electronic data storage with digital display. Higher data density, easier data retrieval, and no consumables.
- Data Loggers: Compact, battery-powered devices for standalone data collection. Ideal for remote or temporary monitoring.
II. Configuration
- Set the correct input type for each channel: thermocouple, RTD, voltage, or current input
- Configure the chart speed appropriate for the process dynamics. Faster speeds for batch processes, slower for continuous monitoring.
- Set the recording range for each channel. Ensure the expected process values are within the recording range.
- Configure alarm setpoints and relay outputs if the recorder includes alarm functions.
III. Maintenance
- Chart Recorders: Replace charts and pens before they run out. Clean the pen mechanism and check for ink flow.
- Paperless Recorders: Periodically backup stored data. Check available memory and archive or purge old data as needed.
- All Types: Verify calibration against a reference standard quarterly. Clean the exterior and check connections.
