Motion and Acceleration Measurement Systems Guide
Motion measurement systems combine position, speed, and acceleration sensors to provide comprehensive motion monitoring for machinery protection and process control.
I. System Integration
- Select sensors that cover the full range of motion parameters required for the application
- Integrate sensor signals into a unified monitoring or control system
- Ensure the measurement update rate is adequate for the fastest motion changes in the system
- Implement diagnostic functions to detect sensor failures or signal degradation
II. Key Measurements
- Position: For valve position feedback, actuator control, and displacement monitoring
- Speed: For rotational machinery, conveyor control, and overspeed protection
- Acceleration: For vibration monitoring, impact detection, and seismic monitoring
III. Maintenance Strategy
- Establish baseline measurements for all monitored parameters
- Set alarm and trip thresholds based on machinery protection standards
- Trend measurements over time to detect gradual changes before failure occurs
- Periodically verify sensor calibration using reference measurement devices
IV. Documentation
- Maintain a sensor inventory with installation dates, calibration records, and replacement history
- Document all alarm and trip setpoints with the rationale for each
- Keep wiring diagrams and configuration files current and accessible
- Review and update measurement system documentation after any modifications
