Abstract
Sello térmico autoregulable térmicamente para marcar. Consiste en un sello térmico para marcar térmicamente, caracterizado porque la temperatura de funcionamiento se genera y autoregula empleando una resistencia eléctrica tipo PTC (Positive Temperature Coefficient), sin necesidad de emplear ni biestables térmicos ni termostatos incorporados o externos, ni otros tipos de elementos de regulación de temperatura. Este tipo de resistencia eléctrica se caracteriza por aumentar su resistencia eléctrica con el aumento de la temperatura, hasta una temperatura máxima a la cual no circula intensidad. A partir de una misma resistencia eléctrica PTC (Positive Temperature Coefficient) se consiguen distintas temperaturas de funcionamiento del sello térmico, variando el ajuste entre la resistencia y su alojamiento, situando flejes calibrados de distintos espesores entre la resistencia y su alojamiento. Todo ello permite un diseño del sello térmico muy compacto, de reducidas dimensiones, autoregulable y autónomo en cuanto a regulación de temperatura, al no depender de elementos externos de regulación de temperatura.
