Abstract
LA INVENCION SE REFIERE A UN SENSOR DE FUERZA, ESPECIALMENTE UNA CELULA DE PESAJE, CON UNA UNIDAD DE APLICACION DE LA FUERZA Y UNA UNIDAD DE SOPORTE, LAS CUALES ESTAN UNIDAS POR MEDIO DE BRAZOS ESTRECHOS DE FORMA ANULAR CON UNA PIEZA DEFORMABLE DISPUESTA ENTRE ELLOS, QUE SOBRE UN LADO SITUADO A UNA DISTANCIA AXIAL DE LOS BRAZOS, PRESENTA ELEMENTOS CONVERTIDORES MECANICOELECTRICOS, PARA LA TRANSFORMACION DE DEFORMACIONES TANGENCIALES Y RADIALES, QUE ESTAN PUENTEADOS ENTRE SI. DEBIDO A LA SITUACION DE LOS ELEMENTOS CONVERTIDORES SOBRE UN SOLO LADO, PUEDEN SER UTILIZADOS BANDAS EXTENSOMETRICAS EN LA TECNICA DE LAMINAS O PELICULAS DELGADAS. LA INVENCION SE APLICA EN APARATOS DE MANIPULACION Y EN LA TECNICA DEL PESAJE.
