VT2-14 - plant eddy current quality surveillance of a surface bars
is intended for the automatic control bars by diameter 2-14 mm on presence of defects leaving on a surface depth more 0.05mm and length more 2mm, automatic piece submission bars in a zone of the control, detection of defects and sortings out on "spoilage" and "suitable", with use of amplitude -phase system of processing of a signal, a digital filtration.
Features of plant:
- Structure: a mechanical part, defectoscope short and defectoscope long defects, a control panel, a case electric
- Initial transformer: :
- Through passage - eddy current
- Superimposed(waybill) - eddy current, dynamic
- Processing of a signal: amplitude -phase
- Adjustment of frequency of excitation: smooth
- Modes: "adjustment", "work"
- System of the automatic signal system of defects
- Opportunity of storing A-Scan and adjustments
Characteristics of plant:
- Frequency of excitation: 100-154 kHz, a step of adjustment - 6 kHz
- Revealed defect:
- - Risk - 0.05х0.1х2.0 mm
- - Risk - 0.05х0.1х50 mm
- Dynamic range - 60 dB
- Depth of adjustment of sensitivity - 30 dB
- Duration of display - 10-20 ms
