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.
對磁通門磁力儀的改進，直流毫高斯計測量磁場強度（技術上的磁通密度）的地球磁場高達幾倍。它有一個分辨率為0.01毫高斯（1納特斯拉）和一系列/ 2000毫高斯（200 microteslas）。儀表的磁阻傳感器在補償磁通門磁力儀在成本和穩定性的主要改進。事實上，這種傳感器接近質子旋進磁力計在溫度穩定性。然而，在只有1毫米×0.2毫米，有源傳感器面積遠小于磁通門磁力儀和質子傳感器。這使得非常精確的磁性測量，在小面積（如薄膜）或高梯度，必要時。
