Glossary

An electrical power supply in which current periodically reverses direction. Required for powering the cRIO and camera enclosures.

A measure of how quickly vibration velocity changes over time, commonly used in vibration analysis to assess fault severity in rotating machinery.

A sensor that measures vibration acceleration and is commonly used for monitoring high frequency machine faults such as bearing defects.

A machine‑learning or statistical modeling method that uses historical sensor data to detect abnormal asset behavior and predict developing failures. InsightCM can send feature data to plant historians for use in APR models.

A hierarchical representation of plant equipment inside InsightCM. Used for organizing devices, configuring monitoring, and associating data with specific assets.

A visualization showing vibration amplitude and phase relative to machine speed; used for diagnosing resonance, imbalance, and rotor dynamic behavior.

A damaging condition in pumps caused by vapor bubble formation and collapse, detectable through high‑frequency vibration patterns.

NI Compact Reconfigurable I/O Controller.

A vibration metric representing how far a component moves from its resting position; often used for low‑frequency machinery such as large turbines.

Local (in‑enclosure) computation that reduces network bandwidth and storage needs by filtering, compressing, or analyzing data before sending it to InsightCM™.

A specialized vibration analysis tool used for early detection of bearing faults by demodulating high‑frequency impacts.

The number of vibration cycles per second (Hz). Changes in frequency patterns help detect imbalance, misalignment, and structural resonance.

A frequency‑domain plot that includes both forward and reverse vibration components; essential for diagnosing rotating‑equipment issues such as unbalance or oil whirl.

A characteristic vibration frequency related to gear tooth engagement; deviations can signal gear wear or eccentricity.

A standardized classification that describes an enclosure’s resistance to dust and water.

A common rotating‑equipment fault where mass is unevenly distributed around a rotor, causing elevated vibration at running speed.

InsightCM™ is application software for condition monitoring with full access to waveforms, multiple sensor technology inputs, enterprise software connectivity, and analytics packages.

input/output

A fault occurring when coupled machine shafts are not properly aligned, causing elevated vibration at 1× and 2× running speed.

A North American standard classifying enclosure protection levels against environmental conditions.

A visualization showing the actual motion path of a rotating shaft using two orthogonal proximity probes; used for high‑end turbomachinery diagnostics.

A vibration measurement representing the total displacement between the maximum and minimum values of a waveform cycle.

A non‑contact sensor used to measure shaft position and displacement in rotating machinery such as turbines and generators.

A condition where machine natural frequencies amplify vibration response; often revealed through frequency sweeps and Bode plots.

A constant voltage applied to certain vibration sensors (e.g., IEPE accelerometers) to power internal circuitry.

The process of converting vibration waveforms into frequency‑domain plots to identify characteristic fault signatures.

A polar chart used to visualize shaft orbit movement relative to bearing clearance; critical for large rotating machinery diagnostics.

A raw, time‑domain vibration signal used to identify impacts, looseness, and transient machine behavior.

The process of recording and analyzing temperature changes over time to detect abnormal patterns or emerging failures.

A vibration measurement representing the speed of movement over time; commonly used to assess overall machine health and compliance with ISO 10816/20816 guidelines.
