Claims

[Scope of utility model registration request]

A gap sensor consists of narrowing the opening of a cavity, placing the opening opposite to the gap whose size is to be measured, placing an air injection nozzle around the cavity toward the surface where the gap exists, and connecting the cavity to a pressure gauge.
