THE HIGH-END ULTRASONIC TOMOGRAPH FOR QUALITY ASSESSMENT OF CONCRETE STRUCTURES: THICKNESS MEASUREMENT UP TO SEVERAL METERS, REBAR LOCALIZATION, FLAW DETECTION WITH ULTRASOUND
A1040 MIRA 3D PRO is a low frequency ultrasonic tomography system suitable for manual and automated assessment concrete structures with extended aperture for extremely deep penetration applications. Due to its novel 64 A-DPC® sensor technology, it provides unbeatable inspection range, flaw detectability and imaging resolution by implementing three-dimensional FMC / TFM in each instrument position.
The instrument consists of two lightweight basic units, each containing 4 x 8 Active Dry-Point-Contact transducers with integrated pulser-received circuits and parallel DAQ electronics wirelessly connected to the powerful smartphone that implements image reconstruction and visualization algorithms by means of parallel graphic processor units on-board. This hardware solution allows achieving the high-end performance for real-time 3D-TFM imaging.
By using special transmitting techniques such as enhanced burst energy an outstanding penetration depth has been achieved in combination with 8 x 8 individually driven A-DPC probes. For additional extending the inspection range arbitrary aperture extension can be utilized by two and more array units in one configuration.
INTROVIEW® Pro – Desktop or Laptop software for remote unit control and 3D visualization & analysis of Big Data is an essential part of the instrument delivered in the standard delivery set.
The open data format for customized developments by user – for offline as well as online applications – complete the functional package of this extraordinary instrument.
