The set consists of two calibration blocks: MD 2-0-1 and MD 2-0-2. The blocks from KMD 2-0 set are based on 40Х13 steel plate. They contain artificial reflectors such as side drilled holes diam. 1.6 mm (for MD2-0-1) or 1.0 mm (for MD2-0-2) that are located at the depth from 0.5 mm to 50 mm.
Main specifications of these calibration blocks are listed in the Table below:
|Parameters||MD 2-0-1||MD 2-0-2|
|Diameter of reflectors, mm||1,6||1,0|
|Occurrence depth of reflectors, mm||0,5 - 50|
|Dynamic range of longitudinal ultrasonic waves, dB||1 ± 0,3|
|Velocity of propagation of longitudinal ultrasonic waves, m/s||6030 ± 30|
