4X Diagnostics has written many training courses and technical papers. We have given presentations at national conferences, Vibration Institute meetings and we teach classes for CSI and Mobius Institute.
Vibration Testing & Analysis
Used to determine the mechanical health of machines. Typical measurements include vibration testing to identify mechanical and electrical issues and Stress Wave measurements to identify bearing and gear faults. Including Route Database Creation & Tune-ups.
Motion Amplification
Motion Amplification is a revolutionary video process that detects subtle motion and amplifies that motion to a level visible with the naked eye.Spectrum and waveform data can be calculated from the video images. 4X Diagnostics is Trained & Certified to complete testing for you.
Remote Data Analysis
Remote analysis and reporting of route based data, online data or any diagnostic measurements.
Operational Deflection Shape
Time or frequency based Operational Deflection Shape (ODS) is used to analyze the motion of rotating equipment and structures. An ODS animates a computer generated model of the machine with phase and magnitude data or simultaneously measured time waveform captures.
Modal Analysis
An experimental method of determining the natural frequencies, damping values and mode shapes of a structure. Modal analysis is needed when machine vibration is amplified due to resonance.
Resonance Testing
Resonant amplification (Resonance) results whenever forced vibration, from mechanical faults, coincides with a natural frequency. A natural frequency is the frequency or frequencies that a machine “likes” to vibrate or “ring”.
Seismic Vibration Studies
Floor vibration, structure or ground vibration monitoring and analysis. Used for vibration sensitive equipment and slow speed equipment.
Short & Long Term Monitoring
Short or long-term monitoring of vibration or process signals. Monitoring instrumentation is 24 channels and is capable of measuring and storing long time waveform captures, trends, spectrums, waveforms.
Sound/Noise
Airborne noise measurement used to diagnose vibration on rotating machines or to investigate neighborhood noise complaints, or document fence-line noise and human exposure levels.
Ultrasonic Thickness/Inspection
Used to determine the thickness of metal castings, metal components and concrete structures.
Fan/Rotor Balancing
Dynamic balancing of rotating equipment in-situ or in a balance stand.
Phase Studies
Relative or absolute phase studies to diagnose or confirm the source of vibration issues.
Turbine Startups
Multi-channel measurement and data analysis of turbine startups and shutdowns. Including Speed, Orbits, Shaft Centerline, and Shaft Position measurements.
Acceptance Testing
To test and evaluate components for compliance & acceptability related to vibration and/or sound.
Transient Capture Analysis
Long time waveform captures used to study periodic or non-periodic signals. Transient capture analysis is commonly used when impacting or randomly occurring signals are present.
Vibration Sensor Installs
Typical installations include spot face/surface prep, epoxy/drill and tap, and connector/junction box wiring.

Operational Deflection Shape (ODS) Sample
An Operational Deflection Shape (ODS) test was made on a BowTech Liberty compound bow. The purpose of the test was to observe the deformation shape of the bow during and after firing the arrow. ODS testing is a
diagnostic measurement technique used on motors, fans, pumps and other rotating machines to reveal the vibratory shape of the machine during normal operation. ODS testing identifies vibration problems resulting
from mechanical defects. Twenty-nine vibration accelerometers were attached to the BowTech Liberty compound bow. Vibration was measured in the “X”, “Y” and “Z” directions. As the arrow was released, all sensor
signals were simultaneously acquired using a Computational Systems, Inc. XP-32 Machinery Health Expert analyzer. The XP-32 is a 32-channel data acquisition system.
