A1040 MIRA

Description

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.

Application

Inspection of concrete constructions up to 2500 mm thickness for the purpose of evaluation of consistency of the construction.

Inspection of reinforced concrete constructions up to 800 mm thickness for the purpose of evaluation of consistency of the construction.
