Abstract
A platform and transducer elements are combined so that the transducer elements form integral components of the platform proper. For this purpose slots are milled, machined or cut into the platform so that two parallel slots define a beam structure, the sensitivity of which is established by drilling holes into the platform, at the end of each slot and intermediate the ends of each slot. Strain gage elements are then secured to the so formed beam structures, the free end of which are operatively connected to support elements. Overload limiting means are so arranged that the flexing of each beam structure is limited to a predetermined value.
