Compressed Air Pressure Monitoring Dashboard

The default band is 6–7 bar typical shop line pressure (set to your tools' requirement plus a margin). Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.

Pressure drop across the distribution system: undersized pipe, too many fittings/elbows, a clogged filter or dryer, or a long run all eat pressure between the compressor and the point of use, and the drop grows with flow — so it's worst exactly when demand peaks. Measure at the machine, not the compressor. Fixes: fatten the main pipe, loop the ring main (feeds both ways), service filters/dryers, and fix leaks (which raise system flow and thus drop). Often you can then lower the compressor setpoint and save energy.

Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.

Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
