Miniature eddy current unit gives 2D image of flaws

M i n i a t u r e eddy current unit gives 2D image of flaws
A small portable ultrasonic scanner for use in research laboratories unable or unwilling to buy a full scale unit was unveiled on the Wells Krautkramer stand.
A miniature eddy current instrument was launched by Staveley Instruments. Costing around £3000 in the UK, the Miniscope 23 has a frequency range of 100 Hz to 2 MHz.
Designed and built by Wells Krautkramer in Sutton Coldfield, UK, the tank and recording mechanism costs around £5000. The firm forsees demand for the unit from teaching institutions and from firms with only
occasional scanning requirements. Also displayed was the software system for ultrasonic scanner data analysis detailed in NDT International February 1988. Able to display the results in real time, plus permanently storing the data, the software and interface costs around £11 000.

New liquid used in high intensity light guide High-intensity liquid light guides were previewed on the Ultrafine Technology stand. The Series 700 is said by the manufacturer to be at least twice as efficient as fibre-optic light guides, giving a high output right across the visible spectrum. The newly developed, organic liquid does not carry ultraviolet or infrared, giving a cold white light which is said to be stable over long distances (eg5 1 0 m ) . The manufacturer forsees applications in endoscopy and other areas in which high intensity visible light is required. It is
hoped that the non-corrosive nature of the liquid will overcome previously held reservations about liquid light guides. Prices of the series 700 will be typically around £150for2m.

X-ray film has high resolution and sensitivity
A computer-controlled eddy current inspection system was shown on the Harwell stand.
High-resolution X-ray film was launched by Du Pont at the show. NDT-30 film is claimed to have the highest contrast, finest resolution and highest sensitivity of all available NDT films.
Designed for shop-floor quality control, batch monitoring and in-service inspection, the units have decision-making capability to permit faulty components to be automatically rejected.

The unit has 24 programme storage capacity and auto liftoff.

Self illuminating light guides, which pick up light from along their length and transmit it to the ends, were also on show for the first time. A very high refractive index, water-based liquid picks up light which is then transmitted by fluorescent molecules in the liquid.
Eddy current units to be designed for specific needs
The J-scan unit was one of what is expected to be a series of tailor-made systems designed to meet specific requirement needs.
Display is via an LCD screen which shows the frequency, gain and alarm gate values being used. A two-dimensional picture of the flaw is also outlined on a graticulated screen area.
Applications are expected to include imaging fibres in composites and stress corrosion cracking in tubing. Resolution is said to be greater than 400 line/mm. NDT-Scan, an electronic digitizer, was also displayed, for the first time in the UK.

The portable Miniscope 23
Ultrasonic system launched An ultrasonic system from I. C. Escoffier was demonstrated on the Sonatest stand. The Symphonic 310 has just been launched, with the first system sold in France in April. The system consists of a processor, software and hardware. The processor excites the probe, amplifies and digitizes the return signal and preprocesses in accordance with the instructions of the computer. Thus the ultrasonic processor can detect defects, measure thicknesses or perform ultrasonic interferometry with changes only in the software employed.
