2.4. The device produced with a basic configuration, focused on
heavy concrete middle marks. For other marks and materials
required calibration and adjustment in accordance with GOST
17624, GOST 24332 and methodological recommendations MDS
62-2.01 control the strength of concrete monolithic structures by
ultrasonic method of surface sounding.
2.5. The device provides a visualization of the received ultrasonic
waves (A signal), has a mode of the oscilloscope for viewing and
analyzing the signals A.
2.6 The device provides operation:
- at the surface sounding with the surface sounding probe on the
fixed base (120 ± 1) mm with a dry contact;
- at the through-sounding with ultrasonic probes at random basis
with contact lubricant or surface and angular sounding with dry
contact (protectors, conical nozzle) or with a lubricant on an random
basis.
2.7. Operating conditions: temperature range: from -
20 ° C to 50 ° C,
relative humidity up to 80% non-condensing humidity, atmospheric
pressure 86 ... 106 kPa.
