  • Device including a planar matrix of fluid filled bags for measuring pressure acting on a support
    Patent number: 5357804
    Abstract: To measure pressure acting on a support (1), a sealed bag (2) which is filled with a fluid and has flexible bag walls (9, 10), and which is arranged on the support (1) and whose interior communicates with a flexible capillary tube (4, 4'), is used as a sensor. Connected to the free end of the flexible capillary tube (4, 4') is an evaluation device which detects pressure variation, it being possible for the end of the flexible capillary tube (4, 4') to be plugged into a block (5). The block has a bore (6) which continues the channel of the flexible capillary tube (4, 4') and is sealed at its end not: subjected to the flexible capillary tube (4, 4') by a diaphragm (7). The diaphragm bulges outwards in the event of a reduction in the volume of the bag (2). The extent of the outward bulging of the diaphragm (7) can be determined by an optical detector (15, 16).
