MIND THE GAP

Gapman Gen3

Capacitec Gapman Gen3 is replacing feeler gauges within the aircraft shimming process. The Capacitec Gapman portable non- contact electronic gap measurement system has replaced feeler gauges and other mechanical contact methods at all major commercial aircraft manufacturers with a non-contact ‘electronic feeler gauge’. Gapman Gen3 is a portable battery operated, non- contact gap measurement system. It includes two capacitive sensors – one looking up and the other looking down installed at the end of a flexible Kapton wand.

The gap between each sensor face to the grounded target is linearly calibrated to digital engineering units. The results can be recorded into internal Gapman Gen3 memory or sent by USB or Bluetooth to a laptop computer.

Feeler gauges can readily measure gaps with in-plane access to parallel surfaces, but in the case of inboard hidden gaps where the gap dimensions change along the length of a long tapered gap, the feeler gauges cannot measure above its own thickness. The advantage of the Gapman Gen3 is the flexibility for its wands to be inserted into gaps with difficult access.
