Analog Gauge Reading

Converts dial gauges into digital readings with alarm thresholds — no sensor retrofit needed.

OKKHI INSPECT · QUALITY CONTROL THAT NEVER BLINKS.

Turns the analog dial gauges already on your equipment into continuously logged digital readings with alarm thresholds — no instrumentation retrofit, no production stoppage, no waiting for the rounds clipboard.

One small camera per gauge cluster and a one-time calibration is all it takes to bring decades-old equipment onto your dashboard.

The problem

A rounds clipboard records each gauge a few times per shift; the trips and the drift happen in between, unwatched.

Who it's for

Plants with legacy dial gauges and no budget for sensor retrofits

The outcome

Manual gauge rounds become continuous digital readings with alerts the moment a threshold is crossed.

How it works

STEP 1Capture

A small camera watches each gauge face from a fixed mount.

STEP 2Locate

The dial and needle are detected and tracked across lighting changes.

STEP 3Convert

Needle angle is converted to engineering units using a one-time calibration.

STEP 4Alarm

Readings stream to your dashboard with thresholds, trends, and alarms.
