Compared with conventional sensors, giant magnetoresistive (GMR) sensor has the advantage of high sensitivity, high reliability, wide measurement range, small volume and low price.
与传统的磁敏传感器比较,巨磁阻传感器具有灵敏度高、可靠性好、测量范围宽、体积小、价格低等优点。
2
The cost of the magneto—resistive sensor is low, so the method has extensive value to use .
由于磁阻传感器成本较低,该方法具有广泛的推广和应用价值。
