A pressure sensing device comprises a substrate having an opening, a pressure sensor die electrically connected to the substrate, and a pedestal having an upper surface that extends through the opening in the substrate, with the upper surface affixed to the sensor die. Because the guide member is rotatably joined to the base member, the rotational position of a post positioned within the guide member can be significantly altered with respect to the base. The method further includes determining a content type to be sent to a mobile device based on preferences provided by the user. The compositions hereof may be added to drilling mud during drilling operations or to fresh water for removing salt depositions.
