A portable handheld ultrasonic tomograph is designed for imaging of the internal structure of concrete at one-sided access.
A portable handheld ultrasonic tomograph is designed for imaging of the internal structure of concrete at one-sided access.
The tomograph represents fully-autonomous measurement unit for collection and tomographic processing of the data obtained. Measurement unit contains a matrix antenna array from 48 (12 blocks, each containing 4 elements) law-frequency broad banded transducers of shear waves with dry-point-contact and ceramic wear resistant tips. Hence they can work with rough surfaces for the long time. Each transducer is equipped with an independent spring suspension, thus allowing inspection on the uneven surfaces. Nominal frequency of the array is 50 kHz.
Instrument’s interface allows working with laser beams which are projected on a surface of the testing object. Hence the operator can correctly maintain a shift step of the antenna array during a complete technical diagnostics of the testing object.
Handheld light-weight body and a repositionable handle provide convenient working with the instrument on the horizontal, vertical and roof surfaces. A reference scale on the lower part of the instrument’s body is designed for convenient localization of the defects relative to the antenna device.
Large and bright TFT display and a keyboard allow easy adjustment of the instrument to the testing object, selection of the required operation modes and conduct an inspection, watching the results obtained, which allows their initial analysis.
An internal rechargeable battery provides operation of the instrument during 5 hours. Increased charge-discharge cycle enhances reliability of the tomograph for long-term application. Besides, the tomograph can be powered directly from the AC mains.
The instrument allows data transfer to the external PC for advanced processing by means of the dedicated software
Inspection is carried out as step-by-step sounding of the testing object with data combining and volume reconstruction over the whole scanned surface of the testing object.
