Abstract
Método para verificar la capacitancia a través de una capa aislante extruida hasta un espesor que se supone uniforme sobre un elemento metálico de sección transversal circular extruido axialmente que avanza, caracterizado pro provocar el avance del elemento aislado (27,28) a través de una sonda capacitiva generalmente cilíndrica que presenta varios segmentos aislados entre si (11-14) dispuestos a lo largo de un lugar geométrico de puntos substancialmente equidistantes del centro axial (15) de dicho elemento y sin estar en contacto con la capa, establecer un potencial eléctrico de referencia por dos medios protectores metálicos no consecutivos (23,24) concéntrica y aislativamente colocados alrededor del centro axial (15) y adyacente a los extremos de la sonda, conectar cada segmento por turno a ambos medios protectores, y medir para cada vez la capacitancia entre el elemento metálico y cada segmento.
