µTomoScan

The µTomoscan is our most economical multichannel UT system. It allows the use of pulse-echo, transmission technique and time-of-flight-diffraction technique (TOFD). It features both logarithmic and linear amplifiers. The µTomoscan is ideal for in-service inspection that requires automated data acquisition, real-time imaging, flaw sizing, etc.The µTomoscan system is built around R/D Tech Tomoview™ a standardized Windows-based software platform for data acquisition and analysis. This software offers the flexibility to configure layouts for any specific application to better meet your particular inspection requirements.

Weld inspection
Based on the Olympus NDT's strong know-how in nuclear, petrochemical, and heavy industry, the µTomoscan includes all the functions required to perform weld inspections. The multichannel µTomoscan offers the possibility to combine TOFD and P/E techniques, which allows more complete and accurate characterization and sizing of defects.
Corrosion mapping and surface inspection
In petrochemical applications, corrosion detection and mapping represent a major portion of the inspection requirement. The aerospace market also requires scanning of large surfaces for disbonding and delamination.

Heavy industry
The use of automated ultrasound NDT equipment in heavy industry provides immediate inspection results and superior flaw sizing. Compared to manual inspections, automated inspection systems guarantee complete coverage, and provide supporting documentation to that effect. Inspection results are provided directly to a computer, and data may be archived and printed.

Industrial NDT
The open architecture design of the hardware and software of the µTomoscan enables it to adapt to plant operation and go-no-go process control. The µTomoscan packaged in an industrial housing along with an industrial computer and MCDU-02 in rack-mount version meet these requirements.
