A1020 MIRA-lite is a low-frequency ultrasonic tomography system for manual ultrasonic testing, 2D and 3D visualization and quality evaluation of concrete and reinforced concrete structures.
The instrument is a hand-held lightweight low-frequency ultrasonic device of general purpose. It is a fully autonomous system used for acquisition, topographic processind and evaluation of pulse-echo ultrasonic data. The sensor system contains a matrix antenna of 32 (8 blocks with 4 elements in each) low-frequency broadband transverse wave dry point contact (DPC) transducers with ceramic wear-resistant tips for long-term couplant-free operation on rough surfaces.
The A1020 MIRA-lite is dedicated for non-destructive testing constructions made of concrete, reinforced concrete and stone with one-sided access. It allows estimation of material integrity by detection of local inclusions, cavities, voids, delaminations, not grouted areas and cracks as well as object thickness measure. Typical application fields of the system are reinforced-concrete buildings, facilities, bridges, tunnels, highways, airdromes in construction and in operation / maintenance. Further the instrument can be used in the mining industry to evaluate the quality of the exploitable minerals.
The A1020 MIRA-lite allows quick and efficient testing of the large objects with its three-dimensional visualization and documentation of the inspection results by means of provided software INTROVIEW-CONCRETE by ACS (in delivery volume).
