Abstract

BRAZO PARA UN TRANSDUCTOR DE FUERZA, DEL TIPO QUE EGENRA UNA SEÑAL DE SALIDA QUE VARIA EN PROPORCION A LOS CAMBIOS EN LA MAGNITUD DE UNA FUERZA APLICADA AL MISMO. CONSTITUIDO POR UN ELEMENTO ESENCIALMENTE CILINDRICO (28) QUE TIENE UNA PARTE PLANA (30) FORMADA A LO LARGO DE TODA LA LONGITUD DE UNO DE SUS LADOS; POR UNA RANURA (32) EN FORMA DE L QUE SE FORMA A TRAVES DEL ELEMENTO (28) CILINDRICO, PARA DEFINIR UNA PARTE DE PALANCA (34) Y UNA PARTE DE BRAZO CONIFICADA (36); Y POR EXTENSIMETROS (44, 46) QUE SE AGLUTINAN O ADHIEREN AL LADO PLANO (30) DEL ELEMENTO CILINDRICO Y QUE TIENEN CONDUCTORES ELECTRICOS QUE SE EXTIENDEN A PARTIR DEL MISMO Y SE CONECTAN A UN CABLE (48), PARA PROPORCIONAR UNA SEÑAL DE SALIDA A UN DISPOSITIVO DE CONTROL (50).
