進(jìn)口電磁超聲探頭
主要特點(diǎn)：可以與傳統(tǒng)的超聲波探傷儀連接，從而實(shí)現(xiàn)不需要耦合劑探傷和測厚的效果。
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主動電磁聲換能器可連接任何傳統(tǒng)的超聲波探傷儀，而不是標(biāo)準(zhǔn)的壓電換能器，使測量金屬物體厚度、搜尋剝落物和其他缺陷成為可能，而無需事*行曲面準(zhǔn)備和使用。由9伏電池驅(qū)動的emt 2705在一次充電的情況下可以連續(xù)運(yùn)行20小時(shí)。emt 2705根據(jù)存在pro的情況自動開關(guān)。
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.
