Abstract

LA INVENCION SE REFIERE A UN SENSOR DE FUERZA O DILATACION, DISPONIENDO DE UN CONDENSADOR (MK) DE MEDICION CUYAS ESTRUCTURAS (ES1, ES2) DE ELECTRODOS DE INTERBLOQUEO, SIMILAR A ESTRUCTURA DE PEINE, DEBEN SER DESPLAZADAS DE FORMA PARALELA UNA CON OTRA A TRAVES DE DOS PUNTOS (BP1, BP2) DE SEGURIDAD COMO UNA FUNCION DE LA FUERZA (F) O DE LA DILATACION ({EP}) A SER MEDIDA. LA CAPACIDAD TOTAL DEL CONDENSADOR (MK) DE MEDICION SE DETERMINA MEDIANTE UN ENSAMBLE PARALELO DE PARES DE ELECTRODOS INDIVIDUALES. UNA VARIACION EN LA CAPACIDAD TOTAL DEL CONDENSADOR (MK) DE MEDICION, ORIGINADO MEDIANTE UNA VARIACION EN LA DISTANCIA (D1) ENTRE LOS ELECTRODOS, SUMINISTRA INFORMACION ACERCA DE LA FUERZA (F) O DE LA DILATACION ({EP}) A SER MEDIDA. LOS PUNTOS (BP1, BP2) DE SEGURIDAD ESTAN LOCALIZADOS EN UNA LINEA (V1) DE UNION QUE ES PARALELA A LA DIRECCION DE LOS ELECTRODOS (E1, E2) Y FORMA UN ANGULO ({AL}) DE 40 HASTA 50 ENCIA 45 DE LA DILATACION ({EP}) A SER MEDIDA, PERMITIENDO UNA VARIACION EN LA DISTANCIA ENTRE LOS ELECTRODOS DEBIDO A LAS DILATACIONES TERMICAS A SER EVITADAS AL MENOS SUSTANCIALMENTE.
