TECHNIQUES SUITABLE FOR USE WITH AN OBJECT FOR MOVING THROUGH A FLUID, SUCH AS A MUNITION OR RECONNAISSANCE PROJECTILE

Abstract:

According to a first aspect of the invention, there is provided an object for moving through a fluid, the object comprising: an outer housing, arranged to be exposed to a hydrostatic pressure exerted by the fluid; a strain gauge, arranged to obtain an indication of the hydrostatic pressure, wherein a first part of the strain gauge is arranged to be in contact with the outer housing, such that the strain gauge is arranged to obtain an indication of the hydrostatic pressure by obtaining an indication of the strain on the housing.
