以两根铁基非晶软磁性薄膜条(0.02×1.0×60mm~3)为铁芯绕成差分复绕初级和次级线圈的探头具有良好的磁敏感特性和温度特性.这种非晶软磁性膜探头的次级输出的倍频信号电平与外界磁场具有良好的线性关系,其磁分辩率可达到10~(-10)~10~(-11)T,而且在-40℃~120℃范围内,温度系数为0．05%/℃.试验表明这种探头同多晶软磁性膜探头相比较,具有体积小、稳定性好、耐用和温度特性好的优点.
Two iron-based amorphous soft magnetic film strip (0.02 × 1.0 × 60mm ~ 3) for the core around the differential winding primary and secondary coil probe has good magnetic susceptibility and temperature characteristics of this amorphous soft The secondary output of the magnetic film probe has a good linear relationship between the multiplied signal level and the external magnetic field, and its magnetic resolution can reach 10 -10 -10 -10 (-11) T, and at -40 ° C. to 120 ° C. ℃, the temperature coefficient is 0.05% / ℃ .Experiments show that this probe has the advantages of small size, good stability, durability and good temperature characteristics compared with the polycrystalline soft magnetic film probe.
