Abstract
A tactile load sensing transducer for providing a continuous electrical readout indicative of the contact and the location of the load on a load receiving plate substantially simply supported by a plurality of reaction supports on the member. Each reaction support includes a member having a preferably integrally formed connecting portion of reduced transverse section so as to be substantially incapable of resisting moments generated by load plate deflection. Each support preferably has a generally 'L' shaped configuration with the preferably integrally formed plate connecting portion formed adjacent the free end of one leg of the 'L' so as to create bending strains in the support. Strain gages are provided on each support to sense the bending strains therein and, the gages on each support are connected in a common Wheatstone bridge to provide an indication of the reaction load on the support. A microprocessor circuit means sums the signals from the bridge to provide total load and also computes ratios of the individual support loads to the total to provide separate output signals for the x and y coordinates of the load location on the plate.
