Glossary
The terms used across this knowledge base, in plain language. Links point to the fuller explanation.
Acceleration RMS
The overall energy of the acceleration signal; emphasises higher-frequency content and often rises first for early bearing or gear problems. A core KPI.
AI anomaly detection
Per-machine anomaly detection that learns a machine's own normal vibration (a Gaussian Mixture Model built from combined velocity RMS) and flags deviations, with no thresholds to set. Raises an event once 4 of 6 consecutive measurements are anomalous. See AI anomaly detection.
Alert
The more severe event level — vibration (or another KPI) high enough to warrant action. Contrast with Warning.
Asset
A machine you monitor (pump, motor, conveyor, gearbox). A device is attached to an asset as a measurement point. See Assets.
Bluetooth
The wireless link used by Treon Industrial Node C (Treon Flow) to reach a gateway, typically within 20–40 m.
Class (classification)
A named set of Warning/Alert thresholds applied to an asset — either a built-in ISO 20816 class or a custom one. See classifications.
Cloud-to-cloud (C2C)
An integration that forwards an instance's data (events, KPI data, metadata; FFT/waveform on Make) to another system over MQTT or HTTP POST. See Cloud-to-cloud.
Crest factor
The ratio of peak to RMS — how "peaky" a signal is relative to its average energy; an early-warning indicator for developing impulsive faults. A KPI.
Device
A physical Treon sensor or gateway. Devices appear in the Devices application and are attached to assets as measurement points.
Event
Something Treon Connect flags about a machine — a threshold breach, an ISO-class breach, or an AI anomaly — at Warning or Alert severity. See Events.
FFT
See Spectrum.
Gateway
The Treon Gateway connects sensors to Treon Connect. One product in two wireless variants: Wirepas (for Treon Industrial Node X) and Bluetooth (for Treon Industrial Node C).
Group
A node in your site hierarchy (region → plant → line). Assets and devices belong to groups, and roles grant access per group. See group hierarchy.
ISO 20816
The international standard for evaluating machine vibration. Its classes define velocity-RMS Good / Warning / Alert zones by machine type, size and mounting. See ISO 20816 classes.
KPI
A key performance indicator — a single number a sensor computes from a measurement to summarise a machine's condition (e.g. velocity RMS, temperature). See the KPIs explained.
Kurtosis
A statistical measure of how "spiky" (impulsive) a signal is; sensitive to early impacting faults such as bearing defects. A KPI.
Magnetic field
A signal captured by Treon Industrial Node X on electric motors, revealing electrical faults (broken rotor bars, winding/supply issues) that vibration alone can miss. Treon Make only. See spectra and waveforms.
Measurement point
A device once it is attached to an asset — the thing whose trends, spectra and events you view in Condition.
Off-state cutoff
A minimum vibration level (around 0.5 mm/s velocity RMS by default) below which a machine is treated as stopped, not faulty, so idle readings don't distort the AI baseline or raise false events.
Operational Telemetry
The event stream for device health and operations (uptime, connectivity, and the result of a configuration/measurement/firmware operation), separate from machine-condition events. See Operational Telemetry.
Peak-to-peak (P2P) / Zero-to-peak (Z2P)
Measures of the signal's swing — the full negative-to-positive range (P2P) or the largest deviation from zero (Z2P); indicators of impacts and shocks. KPIs.
Role
A bundle of permissions (which applications, and Full / Read-Only / No Access per group) assigned to a user. See Users and roles.
RPM
Rotational speed, derived on Treon Industrial Node X from the magnetic-field signal (with a pole-pair count) — the running speed that spectrum peaks are read against. A KPI.
SOP
A standard operating procedure — a PDF attached to an asset (and shown on an event's SOP tab) so a technician has the right instructions to hand.
Spectrum (FFT)
The vibration signal broken into its component frequencies (amplitude vs frequency). Faults appear at characteristic frequencies, so a spectrum turns "vibration is rising" into "what" is wrong. Treon Make only. See reading spectra and waveforms.
Temperature
Surface temperature — a KPI that complements vibration (friction, lubrication or electrical issues). Read on a periodic cycle, so threshold alerts lag fast changes.
Treon Connect
The platform — the cloud service, the web applications and the mobile app — shared by both solutions. See platform and solutions.
Treon Flow
The solution built on Treon Industrial Node C: Bluetooth, KPI-only monitoring for large numbers of less-critical machines.
Treon Industrial Node C
The Treon Industrial Node C — a glue-on, Bluetooth, KPI-only vibration and temperature sensor; the sensor of Treon Flow. See Treon Industrial Node C.
Treon Industrial Node X
The Treon Industrial Node X — a wireless (Wirepas) sensor capturing triaxial vibration, temperature, magnetic field, and FFT spectra and waveforms; the sensor of Treon Make. Also available as Treon Industrial Node X Ex for hazardous areas. See Treon Industrial Node X.
Treon Make
The solution built on Treon Industrial Node X: Wirepas mesh, full vibration analysis (spectra, waveforms, magnetic field) for critical and complex machines.
Velocity RMS
The overall energy of the vibration-velocity signal — the primary indicator for most rotating machinery, the basis of ISO 20816 limits, and the signal the AI model learns. A KPI.
Warning
The lower event severity — elevated vibration to monitor and plan around. Contrast with Alert.
Waveform
The raw vibration signal over a short slice of time (amplitude vs time), captured per axis; shows impacts, modulation and the character of the vibration. Treon Make only. See spectra and waveforms.
Wirepas mesh
The self-forming mesh network Treon Industrial Node X uses: each node can hop through its neighbours to reach a gateway, extending range and adding redundancy. See Networks.
