2) 1-2 and 71.6 ° of angles through 7 normal, the center of circle 50mm of distance 7;
3) 1-4 and 60.8 ° of angles through 7 normal, the center of circle 68.2mm of distance 7;
4) wherein 1-3 and 1-2 are symmetrical; 1-5 and the-13rd is symmetrical;
5) distance between 3 passages is 15mm;
6) probe is the ultrasonic probe of 2-4MHZ.
Experimental test report:
In people's industrial injury test rail, the soft contact integrated transducer of metal defect detection is arranged on test vehicle frame, regulate the test of various inspection speeds.Result is as follows:
| Speed | Core is hindered detectivity | Bolt |
| 5 kilometers/hour | 100% | 100% |
| 12 kilometers/hour | 100% | 95% |
| 17 kilometers/hour | 85% | 80% |
