Straight Probe | |
Mitech standard Straight Probe with the parameters of 4MHz, 10mm is the standard configuration of Mitech series ultrasonic flaw detectors. It is mainly composed of the piezoelectric crystal, damping block and protective film. The ultrasonic wave is emitted from the piezoelectric crystal, through the protective film and couplant enter into the measured workpiece. So for the straight probe, the actual distance of ultrasonic transmission is equal to the workpiece thickness plus protective film and couplant. So the straight probe should be calibrated before using to remove the distance between the protective film and the couplant to reduce the error caused by them and improve the measurement accuracy. The Straight Beam Probe is suitable for flaw detecting of larger parts with various shapes like forgings, castings and so on. | |

The wedge is made of organic glass, which can realize the waveform transformation. In order to avoid errors in calculating the defect distance, before using the angle probe, we need to calibrate its P-delay, angle and forefront. Through calibration, this part of the error can be automatically subtracted, thus improving the measurement accuracy .The Angle Beam Probe is suitable for normal flaw detecting like welds. | |
