Discussion on Maximizing Phase Angle Difference in Eddy Current Testing
The phase angle difference in eddy current testing usually refers to the difference between the phase angle of the surface defect of the tested tube and the phase angle of the through-hole signal under a certain excitation frequency. The bigger the phase angle difference is, the stronger the detection system can distinguish the surface defects from the internal defects, and the stronger the ability to suppress the vibration interference in the inspection of the pipe. It can be seen that the magnitude of phase angle difference reflects the performance of the detection system, which is the pursuit of most eddy current equipment manufacturers.

BKNFX pre multi frequency eddy current hardness sorting instrument
The magnetic induction of the tested material is carried out by the excitation coil. The induced electromotive force received by the detection coil is related to the shape and size of the material hysteresis loop. When the low-frequency sinusoidal excitation voltage is magnetically induced, the induced electromotive force obtained is also sinusoidal waveform, usually including the fundamental wave. By measuring the fundamental wave composition of the induced electromotive force of the detection coil. It can detect the alloy composition and heat treatment status, so as to realize the material hardness sorting.
BKNET series multi-frequency multi-filter eddy current flaw detector
In the field of parts crack and grinding burn detection, the multi-frequency and multi-filter technology developed by Bockner is a great breakthrough in the field of global eddy current technology. It has the following characteristics: Probe abnormal alarm function, mechanical failure and operation error may cause the damage of the probe. If the damaged probe continues to use, it will cause serious missed detection. The multi-frequency and multi-filter eddy current flaw detector can self-check the probe in real time. If the probe is damaged, the operator will be prompted immediately in a striking way to avoid malfunction.
ET- F1 engine cylinder hole eddy current flaw detector
The equipment consists of instrument system, rotating probe system, probe servo system (including probe floating device), detection and positioning system, electrical control system, etc. In order to adapt to the possible large tolerance of shape and position, the device is designed with probe guiding device, collision avoidance device and probe floating device.

Wireless transmission steel tube ultrasonic flaw detector
The system is suitable for automatic detection of internal and external defects of various steel pipes. The principle of ultrasonic flaw detection is that after ultrasonic waves are coupled into the steel pipe by water, the incident wave propagates. When there is a defect in the pipe, the ultrasonic reflection will be caused. The ultrasonic instrument will report the ultrasonic reflected signal to the real-time alarm after the amplified signal processing, and realize the automatic detection of the defect. Transmission ultrasonic equipment is currently the most advanced testing equipment in China.
