    • Disclosed embodiments include apparatus and methods for transferring a pressure to downhole electronics with a pressure transfer medium. An embodiment of the apparatus includes a body supporting a moveable pressure transfer member, a pressure transfer medium contained by the body and the moveable pressure transfer member, and an electronic component disposed in the pressure transfer medium, wherein the pressure transfer member is moveable to transfer a pressure to the pressure transfer medium and the electronic component. Another embodiment of the apparatus includes a moveable enclosure and a non-conductive material, wherein the non-conductive material isolates an electronic component from a downhole fluid and the moveable enclosure is operable to transfer a hydrostatic pressure to the non-conductive material and the electronic component. An embodiment of a method includes transferring a downhole hydrostatic pressure to an electronic component via a flexible package and a pressure transfer medium.

    • A system for use with a subterranean well can include a magnetic sensor, a magnetic device which propagates a magnetic field to the magnetic sensor, and a barrier positioned between the magnetic sensor and the magnetic device. The barrier can comprise a relatively low magnetic permeability material. A method of isolating a magnetic sensor from a magnetic device in a subterranean well can include separating the magnetic sensor from the magnetic device with a barrier interposed between the magnetic sensor and the magnetic device, the barrier comprising a relatively low magnetic permeability material. A well tool can include a housing having a flow passage formed through the housing, a magnetic sensor in the housing, and a barrier which separates the magnetic sensor from the flow passage, the barrier having a lower magnetic permeability as compared to the housing.
    • 与地下井一起使用的系统可以包括磁传感器,将磁场传播到磁传感器的磁性装置,以及位于磁传感器和磁性装置之间的障碍物。 阻挡层可以包括相对较低的磁导率材料。 将磁传感器与地下井中的磁性装置隔离的方法可以包括将磁传感器与磁性装置分离,其中介于磁性传感器和磁性装置之间的屏障,阻挡层包括相对较低的磁导率材料。 井具可以包括具有通过壳体形成的流动通道的壳体,壳体中的磁传感器以及将磁传感器与流动通道分离的屏障,所述屏障与壳体相比具有较低的磁导率。
