The FGM3D is a compact and high performance three-axis magnetometer. It consists of three Fluxgate sensors and integrated electronics, all protected by a waterproof enclosure (IP65) made of PEEK and POM components. It allows precision measurements of static and alternating magnetic fields in three axes.
FGM3D是一款紧凑型、高性能的三☆轴磁力仪。含3个磁通门传感器▽和集成电子，全部由PEEK（聚醚醚酮）和POM（聚甲醛）部件制成的防水外壳进行保护。
The FGM3D has a wide range of applications in the field of science, geophysics, and material inspection. It is also implemented in various medical systems and is being used for civilian, marine and military applications like borehole measurements or long term measurements of the Earth's magnetic field. 同时也〗应用到多种医疗系统，用于民用、海洋及军事，比如钻孔测量或者长期的地球磁场测量。
FGM3D可广泛应用到科学、地球物理和材料检验领域。
The sensor can be powered from any ±15 V supply. In its basic configuration, the device provides a measuring range of ±100 μT. Other available ranges are ±75 μT, ±125μT, ±250 μT, ±500 μT and ±1.000 μT. Due to the design and the principles of measuring with Fluxgate sensors, the use of FGM3D assures low offset errors, low internal noise and high stability.
传感器电源为±15 V。 在基本】配置中，设备量程为±100 μT，可选其他范围±75 μT，±125μT， ±250 μT， ±500 μT及 ±1.000 μT。由于磁通门传感器的设计及测量原理，应用FGM3D保证♀了低误差补偿，内部噪音低及稳定性高。
While the measurement of all three field components is done simultaneously, the output of all measurement data is separate for every axis. That enables a flexible processing and interpretation of the data thus making the sensor an essential part of complex measurement systems for various purposes.
三轴的部件同时进行测量，但是每个轴的测量数据单独输出，这样数据得以灵活处理及解释，从而使传感器成为各种应用目的中复杂测量的重要组成部分。
