In an exemplary embodiment, the planar sensing element (80) is secured by inclusion of a disk element support provided between the lower end of an inner shield and the lower shoulder of an outer shell for containing such shield, whereby the diameter of the disk element support is less than that of the shell to allow such disk element support to shift off-center. In a preferred embodiment, the planar sensing element is secured by incorporation of a mesh element support, comprising fine wire material and vermiculite filler.
