Abstract

ESTE TIENE MEMBRANAS SUJETAS EN SU REBORDE (12, 32) EN EL QUE UNA CONEXION DE PUENTE COMPLETA ASI COMO INTERMEDIA CONTACTADA POR MEDIO DE VIAS CONDUCTORAS RECUBIERTAS (17, 18, 19; 42, 43, 44, 45, 46, 47, 48) QUE CONTIENE DOS O CUATRO RESISTENCIAS DE OHM APLICADAS EN LA TECNICA DE CAPA GRUESA (15, 16; 35, 36, 37, 38), DE TAL MANERA QUE LAS RESISTENCIAS ESTAN SITUADAS UNAS DETRAS DE OTRAS EN SU DIRECCION DE IMPRESION A UNA DISTANCIA MINIMA Y ASI LA DIRECCION DE IMPRESION (40) COINCIDE CON EL EJE LONGITUDINAL (L) DE LAS RESISTENCIAS QUE ESTAN SITUADAS UNA DETRAS DE OTRA, DE TAL MANERA QUE LA RESISTENCIA CERCANA AL BORDE (15; 35, 38) ESTA SITUADA FUERA DE LA ZONA DE LA MEMBRANA CON UNA DILATACION/APLASTAMIENTO MAXIMO. ADEMAS SE LOGRA UNA MEJORA A LA INSENSIBILIDAD DE TEMPERATURA DE LA SEÑAL DEL SENSOR, UN ELEMENTO SENSOR MEJORADO, UN VALOR ABSOLUTO DEL PUNTO 0 (OFFSET) MINIMO Y UNA MEJORA EN LA ESTABILIDAD A LARGO PLAZO.
