Systems and methods for testing steam traps or other similar devices in a hot water or steam system are described. A tester includes a wand that is handheld that can communicate with a handheld electronic device which in turn can communicate with a central monitor for storing and compiling readings as historical profile data. The wand includes a probe to physically contact the device to acoustically sense the performance of the device. The probe includes a probe tip and a stack of acoustic elements, an electrode, a stack mass, and a head to covert the acoustic signal into an electrical signal. The handheld device includes circuitry to process the information, interact with the user, and transmit information to and from the handheld electronic device and/or the central monitor.

A system includes an inspection robot for performing an inspection on an inspection surface with an inspection robot, the apparatus comprising a position definition circuit structured to determine an inspection robot position on the inspection surface; a data positioning circuit structured to interpret inspection data, and to correlate the inspection data to the inspection robot position on the inspection surface; and wherein the data positioning circuit is further structured to determine position informed inspection data in response to the correlating of the inspection data with the inspection robot position, wherein the position informed inspection data comprises absolute position data.

Apparatus is provided having an acoustic-based air probe with an acoustic source configured to provide an acoustic signal into a mixture of concrete; and an acoustic receiver configured to be substantially co-planar with the acoustic source, to respond to the acoustic signal, and to provide signaling containing information about the acoustic signal injected into the mixture of concrete.

Disclosed is an inspection probe of an inspection system that includes an ultrasonic probe that is freely movable on a test object and irradiates the test object with an ultrasonic wave to detect a reflected wave, and a calculation unit that executes arithmetic processing according to a detection result according to the ultrasonic probe to acquire a flaw detection result of the test object. The inspection probe includes a chassis that is freely movable on a sheet material where a two-dimensional pattern disposed on the test object and indicating a position on the test object is drawn. The ultrasonic probe is fixed to the chassis so that an incident point of an ultrasonic wave that is incident onto an opposing surface of the test object from the ultrasonic probe is within an angle of view of the reader which reads the two-dimensional pattern.

A multi-material inspection system and velocity measurement method of critically refracted longitudinal wave based on single-angle wedges belong to the field of nondestructive testing of high-end equipment. The method includes the following steps: designing a transmitting wedge and a receiving wedge with the same inclination angle, and building phased array ultrasonic-based inspection systems of critically refracted longitudinal wave; estimating a longitudinal wave velocity range of a material to be tested, calculating and optimizing a phased array ultrasonic delay law, and building a relation between a longitudinal wave velocity and an amplitude of critically refracted longitudinal wave; reading and interpolating the arrival time of a received signal, and calculating a longitudinal wave velocity of the material to be tested; determining an optimal delay law, and exciting and receiving a critically refracted longitudinal wave.

A measurement probe edge guide tool includes an edge follower comprising two edge contact pins that spin around the outside of the measurement probe using a ball bearing. The edge contact pins hug the corner of a contoured edge of the workpiece or in-service part to provide a consistent distance of the center of the probe from the edge. The edge follower enables the tool to inspect the marginal portion bounded by a contoured (machined) edge of a workpiece or part. The edge follower is removable so that the tool may also be adapted for use in general acreage inspection. The tool features a spring-loaded mechanism with a positive probe protrusion relative to a roller-supported cage. The tool has either a handle which is coupled to the cage by means of a universal joint or a hand grip that is affixed to the cage.

Non-limiting examples of the present disclosure relate to devices, systems and methods for conducting non-destructive evaluation (NDE) of a wooden specimen, where structural integrity of the wooden specimen is assessed without being compromised. A non-limiting example of a wooden specimen is a wooden utility pole. One or more NDE devices, attached to the wooden specimen, are configured to transmit and/or receive ultrasonic signals to execute NDE of the wooden specimen. An exemplary NDE device may be controlled by another computing device via a data transmission connection. Examples described herein pertain to a variety of coverages that comprise but are not limited to: coverage for a single NDE device; coverage for a system of two or more NDE devices that are utilized to conduct NDE of the wooden specimen; and coverage where one or more NDE devices interface with one or more computing devices to conduct NDE of the wooden specimen.

An ultrasonic inspection system includes an ultrasonic probe and an analyzer. The probe includes a flexible delay line and an ultrasonic transducer array at a first delay line end. A second delay line end can contact a target. The analyzer can receive ultrasonic echoes from the ultrasonic transducers representing amplitude of ultrasonic signals reflected from the target as a function of time from transmission. The analyzer determines a maximum amplitude of the echoes received by each transducer, scale the maximum amplitudes based upon a greatest maximum amplitude, and bin the scaled maximum amplitudes. The analyzer assigns each bin a color and generate a C-scan based upon the scaled amplitudes. Each C-scan pixel can correspond to at least one transducer, and the relative position of each C-scan pixel can correspond to the relative position of the ultrasonic transducer represented by the pixel. Each pixel can be displayed with its assigned color.
