摘要:
Alerting a user of a material inspection device to a change in thickness of a material being inspected is disclosed. A thickness offset is determined from calibration information. The calibration information identifies a time of flight of a pulse through a reference sample similar in composition to a material to be inspected. The thickness offset indicates when a thickness of a material being inspected differs from a thickness of the reference sample. A calibration thickness alarm is set, the calibration thickness alarm corresponding to the thickness offset. A change in thickness of the material being inspected is detected. The calibration thickness alarm is engaged to alert the user of the inspection device of a detected change in thickness of the material being inspected.
摘要:
A system and method for carrying out non-destructive testing and inspection of test objects to assess their structural integrity uses a calibration module configured to provide V-Path time of flight (TOF) correction data over a plurality of object thickness points, obtained from an object or objects having known thicknesses using the same physical probe as is used for the inspection measurements. When a probe launches acoustical waves into a test object and an instrument and a control system compute a time of flight value of the acoustical waves launched by the probe, the pre-obtained V-Path TOF correction data is used to correct the measured time of flight computed by the instrument.

Disclosed is a Hall sensor probe that configured to be coupled with one of a plurality of magnetic targets for measuring the thickness of a non-ferromagnetic wall. The probe comprises a magnetic field source, a Hall sensor, a concentrator and a main housing. The novel aspects of the probe include a wear tip that is exchangeably affixed onto the main-housing, leaving a permanent gap from and disjoined from the concentrator in a manner that transfers stress from the tip directly onto the main-housing. To serve every aspects of the primary objective, being it mechanical, thermal and operational, the material of the tip preferably has a fracture toughness higher than 20 MPa·m1/2, wear coefficient higher than 100, and a magnetic susceptibility lower than 0.001.
