摘要： A sensor measurement of an article having an article surface shape is performed using a hand-held senor probe having a probe housing, a sensor support rotatably mounted in the probe housing and having an orienting structure defined thereon. The orienting structure is preferably an orienting face with substantially the article surface shape. A sensor, such as a eddy current sensor, is affixed to the sensor support and is operable through the orienting face of the sensor support. The orienting face of the sensor support is pressed against the article surface to orient the sensor support and thence the sensor relative to the article surface, and the sensor measurement is performed. The sensor is preferably a ball having the orienting face thereon, and mounted to the probe housing in a ball-and-socket relationship.

摘要： A rotor disk is inspected using an inspection apparatus including an inspection fixture which has a base, and at least one guide extending from the base. Each guide is slidably engagable to one of the rotor slots of the rotor disk and has a guide side shaped to slidably conform to the rotor slot side, and a guide bottom having a guide bottom surface which, in combination with a slot bottom surface, defines an elongated inspection cavity extending parallel to the axis of revolution of the rotor disk. The inspection fixture is mated to the rotor disk such that each guide slides into one of the rotor slots. A sensor apparatus includes a sensor, such as an eddy current sensor, sized to slide into the inspection cavity with a close facing relation thereto, and a sensor drive that moves the sensor parallel to a direction of elongation of the inspection cavity. Inspection is performed by inserting the sensor into the inspection cavity, and sensing the rotor slot bottom using the sensor.
