Inspection, measuring and

testing

Advanced ultrasonic thickness gauge OLYMPUS NDT has introduced the handheld 45MG ultrasonic

Olympus 45MG ultrasonic thickness gauge

element transducer option, the 45MG is capable of making accurate thickness measurements on many materials, including metals, plastics, composites, glass and ceramics. This feature allows for very precise measurements with a resolution of 0.0001" or 0.001mm. The optional single element High Penetration feature enables the gauge to take measurements on very thick or highly attenuating materials, such as cast metals, rubber and fibreglass. The Olympus 45MG is built for use in a wide range of weather conditions and difficult inspection environments. Its sealed case is designed to meet IP67 requirements in order to withstand the rigours of very wet or dusty environments. The transflective colour LCD with QVGA resolution provides readability, from bright sunlight to complete darkness. The 45MG features a simple keypad that can be operated with either the left or right hand for easy access to all important gauge functions. It is designed for use with all single and dual element thickness gauge transducers, and offers standard features such as sound velocity readings, time-of-

thickness gauge, an advanced, small- sized thickness gauge packed with measurement features and software options. The instrument is compatible with the complete range of Olympus dual element and single element transducers, making it an all-in-one solution for thickness gauge applications ranging from wall-thinning measurements of internally corroded pipes using dual element probes, to precise thickness measurements of thin materials using single element transducers. Ultrasonic thickness measurements are accurate, reliable and repeatable, and instant readings can be achieved from one side of a material, making destruction of the part unnecessary. The 45MG features powerful standard thickness measurement features and specialised software options. For corrosion detection applications, the gauge offers optional Thru-Coat ® and Echo-to-Echo technology for measuring thickness with no need to remove paint and coatings, and time-based B-scan, which converts live thickness readings into cross-sectional drawings. When used with the code-activated single

flight readings, differential mode, and reduction rate mode. An optional data logger provides internal storage capacity of inspection data equivalent to more than 475,000 thickness readings, or 20,000waveforms in various file formats, while the MicroSD card slot provides additional storage. The GageView interface program allows for data transfer with a standard USB cable.

Digital inline profile projector KJM GmbH, Germany, has developed Geokon, a high-precision 2D profile inline measurement system for all types of profiled products during production. Four sensors acquire four images of the object. The data is then analysed on the system computer by image processing software. Rectangular profiles as well as complex profiles can be measured.

name (eg R15), defining tolerance or intervention levels and saving the parameters. For a new measurement, only the article to be measured must be selected. The results are displayed numerically as well as graphically. An exclusively numerical display of important dimensions in large numbers can be selected. Values outside of tolerance are highlighted in colour. Measurement results are saved, printed or transferred to computer-aided production data acquisition PDA or QM-systems, according to customer requirements.

The profile types can be entered as CAD-data in the DXF file format using the “Teach-In” program. This allows new products to be defined very simply. The technical drawing must be saved in DXF-format and entered into the “Teach- In” program. The measurement parameters are then defined, as in CAD programs, by entering dimensions, creating a
