Rotational speed progress bar

Who it’s for

Maintenance engineers, machine operators, and plant supervisors ask “how much of the speed range is being used right now and which operating band does it fall in?” They need a bar that shows position within the operating range at a glance.

What it does

A device reporting rotationalSpeed = 1200 RPM renders a horizontal bar filled to 24% of the 0–5000 RPM range, with the fill color indicating operating level: blue for Low (below 500 RPM), green for Normal (500–1500 RPM), orange for Elevated (1500–3000 RPM), and red for High (above 3000 RPM).

• Horizontal progress bar shows position within the 0–5000 RPM operating range
• Color-coded fill indicates operating band without requiring the operator to read the number
• Shows one asset’s data per widget; add multiple widgets to monitor different motors or drives side by side

How to set up

Data keys

Key	Role	Type	Description
rotationalSpeed	Bar value	Timeseries	Rotational speed in RPM; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled Rotational speed, 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 (RPM)	Level	Color
0–500	Low	Blue
500–1500	Normal	Green
1500–3000	Elevated	Orange
3000+	High	Red

How to customize

• To change the operating thresholds — open the widget settings and adjust the band boundaries to match your machine’s rated speed range.
• To change the bar colors — edit the color for each operating band in the widget settings.
• To change the bar range — adjust the minimum and maximum values in the widget settings to match your machine’s full-scale speed range.

Tips

• Stack multiple progress bars vertically to compare speeds across several drives on a single dashboard — the bar format is compact enough to fit 6–8 motors in a column without scrolling.
• A bar that fluctuates between blue (Low) and green (Normal) during a single shift suggests drive instability or process load variations — investigate before the instability causes a trip.
• Pair with a vibration progress bar on the same row for a side-by-side mechanical state view of each rotating assembly.
