Abstract
LA INVENCION SE REFIERE A UNA SENSOR DE FUERZA O DILATACION, DISPONIENDO DE UN CONDENSADOR (MK) DE MEDICION DEL QUE LAS ESTRUCTURAS (ES1, ES2) DE ELECTRODO DE INTERBLOQUEO, CON ESTRUCTURA SIMILAR A PEINE, PUEDEN SER MOVIDAS DE FORMA PARALELA UNA CON RESPECTO A OTRA A TRAVES DE DOS PUNTOS (BP,1 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 POR MEDIO DE UN ENSAMBLE PARALELO DE PARES DE ELECTRODOS INDIVIDUALES. UNA VARIACION EN LA CAPACIDAD TOTAL DEL CONDENSADOR (MK) DE MEDICION, ORIGINADA MEDIANTE UNA VARIACION EN LA DISTANCIA (D1) ENTRE LOS ELECTRODOS, SUMINISTRA INFORMACION ACERCA DE LA FUERZA (F) O DILATACION ({EP}) A SER MEDIDA. UNA VARIACION ENTRE LOS ELECTRODOS ORIGINADA MEDIANTE DILATACION TERMICA SE COMPENSA COMO SIGUE: UN CONDENSADOR (KK) DE COMPENSACION DE DISEÑO, IDENTICO AL DEL CONDENSADOR (MK) DE MEDICION Y PERPENDICULAR CON EL, SE CONECTA EN SERIE DE FORMA RELATIVA AL CONDENSACION (MK) DE MEDICION, SIENDO SELECCIONADOS LOS PUNTOS (BP3, BP4) DE SEGURIDAD DEL CONDENSADOR (KK) DE COMPENSACION DE TAL FORMA, QUE LAS VARIACIONES TERMICAS EN LA DISTANCIA (D1, D3) ENTRE LOS ELECTRODOS DEL CONDENSADOR (MK) DE MEDICION Y EL CONDENSADOR (KK) DE COMPENSACION TIENEN SIGNOS OPUESTOS.
