进口电磁超声探头
主要特点：可以与传统的超声波探伤仪连接，从而实现不需要耦合剂探伤和测厚的效果。
EMT2705 active electromagnetic-acoustic transducer can be connected to any traditional ultrasonic flaw detector instead of the standard piezoelectric transducer and makes it possible to measure thickness of metal objects, search for exfoliations and other flaws without advance surface preparation and usage of couplant. The EMT2705 powered by 9-volt battery can continuously operate 20 hours on a single battery charge. The EMT2705 switches on and off automatically depending on the presence of probe pulses to save the energy when standing idle.
emt2705主动电磁声换能器可连接任何传统的超声波探伤仪，而不是标准的压电换能器，使测量金属物体厚度、搜寻剥落物和其他缺陷成为可能，而无需事先进行曲面准备和使用。由9伏电池驱动的emt 2705在一次充电的情况下可以连续运行20小时。emt 2705根据存在pro的情况自动开关。
EMT2705P is a EMT2705 transducer modification that uses polarized shear wave. The EMT2705P allows user to identify and measure the anisotropy of rolled steel that, in turn, gives a picture of the stress distribution in the metal and identifies areas with the stress-strain state.
