Abstract: A scanner system and method for acquisition of position-based ultrasonic inspection data are described. The scanner system includes an inspection probe and a first non-contact linear encoder having a first sensor and a first scale to track inspection probe position. The first sensor is positioned to maintain a continuous non-contact interface between the first sensor and the first scale and to maintain a continuous alignment of the first sensor with the inspection probe. The scanner system may be used to acquire two-dimensional inspection probe position data by including a second non-contact linear encoder having a second sensor and a second scale, the second sensor positioned to maintain a continuous non-contact interface between the second sensor and the second scale and to maintain a continuous alignment of the second sensor with the first sensor.

Abstract: Devices and methods for testing the operation of acoustic devices such as ultrasonic probes. The disclosed devices and methods identify failures of individual piezoelectric elements of various types of ultrasonic probes free of family-specific adapters to interface with such probes and free of acoustic coupling fluids or the like to establish acoustic coupling with the probes. In one arrangement, a testing appliance is disclosed that includes a testing unit and first and second probes electrically connected thereto. After an operator has established electrical connections between the first probe and a first contact of a connector assembly of the acoustic probe and between the second probe and a ground return path of the connector assembly, the testing device may pass a current through an electric circuit between the first and second probes and determine one or more corresponding electrical quantities of the circuit for establishing statuses of the probe.

Abstract: Method and apparatus for the non-destructive inspection of a test object with a large material thickness by means of ultrasound. The apparatus includes an ultrasonic test probe with an ultrasonic transducer divided into a plurality of individually activatable transducer segments wherein the transducer segments are concentric circles or rings, or sections thereof. A first group j (j=1, 2, 3, . . . ) of transducer segments is selected in such a way that a parallel activation of these transducer segments results in a circular active surface Fj of the ultrasonic transducer (22). An ultrasound inspection of the test object is undertaken with the first group j (j=1, 2, 3, . . . ) of transducer segments, wherein they are activated in parallel.

Abstract: A system and method for detecting and locating the interface emulsion or rag layer in a separator vessel makes use of an acoustic property approach or an imaging approach. Both approaches use ranging and longitudinal mode reflectance and are non-ionizing. The signals are sent through the fluid medium residing in different zones of the vessel, not through the vessel wall or a probe surrounded by the fluid medium. The acoustic property approach uses differences in acoustic impedance between the oil, rag, and water layers that create an echo detected by transit time measurement. Also, the velocity of sound, density, viscosity and attenuation can be calculated for each fluid in order to determine whether the medium is oil, rag, or water. The imaging approach uses differences in amplitude reflectance at these interfaces to create a brightness mode image of the different layers by each amplitude mode scan line being added spatially.

Abstract: System and method for enabling ultrasonic inspection of a variable and irregular shape. The system comprises one or more ultrasonic pulser/receivers, one or more ultrasonic transducer arrays, a shoe or jig to hold and position the array(s), data acquisition software to drive the array(s), and data analysis software to select a respective best return signal for each pixel to be displayed. This system starts with information about the general orientation of the array relative to the part and a general predicted part shape. More specific orientation of the transmitted ultrasound beams relative to the part surface is done electronically by phasing the elements in the array(s) to cover the expected (i.e., predicted) surface as well as the full range of part surface variability.
