Abstract (en)

[origin: WO9843043A1] A strain measuring device for measuring strain in a ship or submarine has a digital displacement transducer (1) for sensing displacement at a point on the vessel. Processors (3, 4) convert the sensed displacement to a strain value and compensate for dc offset and zero drift of the strain value. Digital filters (21, 22) separate the strain value into components representing wave and slam induced strain which are output as compensated wave and slam induced strain values.
