Core insight

A dashboard tells you what the system is doing. A digital twin tells you what it should be doing. The gap between those two is where engineering intelligence lives.

Try it

Inject a fault using the toggle in the left panel. Watch what the conventional dashboard does — and does not — show you. Then switch to With Digital Twin to see what changes.

Physics computed client-side from closed-form equations. All constants from published datasheets and engineering standards.
