Vibration range chart

Who it’s for

Maintenance engineers, reliability technicians, and plant operators ask “how long has this pump been in each vibration severity band over the shift or week?” They need a chart that shows not just current vibration but the time spent in each zone.

What it does

A device reporting vibration = 2.1 mm/s renders a time-series area chart overlaid on horizontal color bands: green for Good (below 2.8 mm/s), orange for Moderate (2.8–4.5 mm/s), dark orange for Elevated (4.5–7.1 mm/s), and red for High (above 7.1 mm/s). The chart background is divided into ISO 10816 zones so technicians can instantly see which severity band the vibration occupies at any point in time. A data zoom slider lets operators examine any sub-period in detail.

• Color-banded area chart shows vibration trend against ISO 10816 severity zone boundaries simultaneously
• Data zoom slider lets technicians focus on any time window — a full shift, a run-up after maintenance, or a specific vibration event
• Shows one asset’s data per widget; add multiple widgets to monitor different pumps or motors side by side

How to set up

Data keys

Key	Role	Type	Description
vibration	Chart series	Timeseries	Vibration velocity in mm/s; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled Vibration, so it draws random values until you point the datasource at a device and rename the key.

To point it at your own device: open the dashboard in edit mode, open the widget’s Datasources, pick the entity or entity alias, and replace the function key with the key your device reports.

Value ranges

Range (mm/s)	Level	Color
0–2.8	Good	Green
2.8–4.5	Moderate	Orange
4.5–7.1	Elevated	Dark Orange
7.1+	High	Red

How to customize

• To change the severity thresholds — open the widget settings and adjust the band boundaries to match your machinery class per ISO 10816.
• To change the band colors — edit the color for each severity band in the widget settings.
• To rename the units label — change the Units field in the widget settings if needed.

Tips

• Use the data zoom slider to isolate the period immediately after a maintenance intervention and confirm that vibration returned to the Good band — this validates the repair and provides a baseline for the next inspection cycle.
• A line that spends increasing time in the Moderate band over consecutive shifts is a reliable indicator of progressive bearing wear — use this chart to track the degradation slope and predict when the Elevated threshold will be crossed.
• Pair with an efficiency range chart on the same row to see whether vibration increases align with efficiency decreases, a two-variable signature that helps distinguish mechanical issues from process-related changes.
