Abstract
Hydraulic scales for weighing the sick comprise a pressure transducer of electromechanical type. A cylindrical block supports on its upper face three rest zones and a support plate with three resilient bellows co-operating with the rest zones. The central part of the cylinder contains a pressure chamber enclosing an incompressible fluid. The upper part of the chamber is defined by the support plate while a deformable membrane with attached strain gauge forms the lower part. The output of the strain gauge is fed to a processing circuit and display for weight read out.
