Description
描述
An improvement on the flux gate magnetometer, the DC Milligauss Meter measures magnetic fields (technically flux density) up to several times the strength of the Earth field. It has a resolution of 0.01 milligauss (1 nanotesla) and a range of /-2000 milligauss (200 microteslas). The meter’s magnetoresistive sensor is a major improvement over an uncompensated fluxgate magnetometer both in cost and stability. In fact, this sensor approaches a proton precession magnetometer in temperature stability. However, at only 1 mm x 0.2 mm, the active sensor area is much smaller than fluxgate magnetometer or proton sensors. This allows very precise magnetic measurements in small areas (such as thin films) or with high gradients, when necessary.
对磁通门磁力仪的改进，直流毫高斯计测量磁场强度（技术上的磁通密度）的地球磁场高达几倍。它有一个分辨率为0.01毫高斯（1纳特斯拉）和一系列/ 2000毫高斯（200 microteslas）。仪表的磁阻传感器在补偿磁通门磁力仪在成本和稳定性的主要改进。事实上，这种传感器接近质子旋进磁力计在温度稳定性。然而，在只有1毫米×0.2毫米，有源传感器面积远小于磁通门磁力仪和质子传感器。这使得非常精确的磁性测量，在小面积（如薄膜）或高梯度，必要时。
