EDI maintains a full range of instrumentation for use in diagnostic studies.
EDI maintains a large inventory of instrumentation including accelerometers, proximity probes, pressure transducers and torsiographs, all of which are essential to the analysis of rotating equipment.
- Piezoelectric Accelerometers – provide vibration levels in acceleration (g’s), velocity (IPS), or displacement (mils). Useful over a broad frequency range (0.5 Hz -15kHz).
- Linear Variable Displacement Transducers – useful for very low frequency or large displacement vibration. Also useful as a static position indicator.
- Strain Gages – can be installed to directly measure dynamic & static stress levels.
- Proximity Probes (Non-Contacting) – inductive device to measure displacement.
- Operating Deflection Shape (ODS) – EDI routinely obtains ODS and Mode Shape measurements on all types of equipment and structures.
- Motion Amplification Camera
- Impact Test Data – Impact Tests are used to determine mechanical natural frequencies of various components (vessels, pipe spans, etc.).
- EDI Data Acquisition System – EDI’s proprietary software combined with the latest instrumentation enables us to simultaneously acquire and evaluate over 128 channels of data.
- Custom Shakers
Strain measurements are used for both static and dynamic diagnostics for shafting, piping, bolted joints, etc. Some of the applications for strain gages include:
- Evaluation of fatigue and field.
- Natural frequency testing (impact testing).
- Shaker Testing
- Pulsation measurement in high pressure systems.
- Bolt-up strain.
- Torsional vibration testing (with telemetry).
Both “glue-on” and “weld-on” gages for high temperature applications are available.
