ABSTRACT:
A gauge for determining the existence of irregularities in a surface of an article includes a housing and a probe having a fluid outlet for the passage of fluid under pressure therethrough which is mounted within the housing for movement between neutral and a sensing position. The gauge further includes a sensor for detecting the pressure of the fluid in the sensing position of the probe. A micro switch, normally spaced from the probe is adapted to signal an extreme movement of the probe beyond the sensing position when no material of the part tested is present. A modified gauge replaces a probe valve and includes a control sleeve and a push arm which engages a second micro switch in the electrical circuit responding to any retraction of the probe. A method is also disclosed, including the steps of moving the probe between a neutral and sensing position and detecting the pressure of the fluid in the sensing position of the probe.
