The result shows that under the constant current exciting mode, the exciting magnetic field is the strongest and has a focusing effect, which improves the eddy detection sensitivity considerably.
结果表明,在恒流激励方式下的激励磁场最强,且具有聚焦效果,因而可有效地提高涡流探伤的灵敏度。
A special IC, so called Integrated Sensor-Heater Constant Temperature Rectifying Circuit, has been developed for SJ-2 Digital Eddy Current Displacement and Vibration-Amplitude Meter.
