摘要:
差动变压器式传感器是一种广泛应用于工业生产现场的传感器,由于决定这类传感器输出特性的结构参数较多,如线圈匝数、磁芯直径、骨架材料和几何形状等,因此在系统参数优化配置时较为困难,实际中都选择优质材料和高精度的加工工艺来保证优良的输出特性.研究了(Fe50Co50)72B20Si4Nb4铁基块状金属玻璃(Bulk Metallic Glass,简称 BMG)作为差动变压器式位移传感器的磁芯材料的传感特性;实验结果表明:在相同条件下 ,采用金属玻璃作磁芯的传感器灵敏度比用波莫合金灵敏度更高,稳定性更好,信噪比更大,在较高的激励电源频率ω下铁损更小;而且金属玻璃制成的磁芯尺寸小、电阻率高、涡流损耗小,因此能把电流的重复频率取得比较高,有效地扩展了传感器的频率响应范围.
Abstract:
Differential transformer sensor is a kind of sensor widely used in industrial production site, because of the structural parameters that determine the output characteristics of such sensors, such as the number of coil turns, core diameter, skeleton material and geometry, etc., so it is more difficult to optimize the configuration of system parameters, in fact, high-quality materials and high-precision processing technology are selected to ensure excellent output characteristics. The sensing characteristics of (Fe50Co50)72B20Si4Nb4 Bulk Metallic Glass (BMG) as the core material of differential transformer displacement sensor were studied. The experimental results show that under the same conditions, the sensor using metal glass as the core has higher sensitivity, better stability, greater signal-to-noise ratio, and smaller iron loss at higher excitation power frequency ω. Moreover, the core made of metal glass has a small size, high resistivity and small eddy current loss, so the repetition rate of the current can be relatively high, which effectively expands the frequency response range of the sensor.
