ABSTRACT:
An electronic gap measuring tool which is inserted into a gap, and then gives an instantaneous digital readout on a depth gage. The digital data on the reading can be entered into an electronic data collector, resulting in a paperless data collection system. The electronic gap measuring tool includes a tool housing and a longitudinally displaceable shaft supported within the tool housing. A roller is mounted to the lower end of the longitudinally displaceable shaft, and a lateral extension is secured to the longitudinally displaceable shaft, such that the roller and lateral extension are longitudinally displaceable therewith. A measuring tab is defined at a lower end of the tool housing, such that a gap to be measured is defined between the measuring tab and the longitudinally displaceable roller. A digital gage is secured to the housing and has a measuring probe which contacts and is biased against the lateral extension to measure any displacements of the lateral extension and roller, such that the digital gage produces a direct digital reading of the gap defined between the measuring tab and the longitudinally displaceable roller.
