Abstract

Un dispositivo de detección de escarcha para detectar la adhesión de escarcha, una abertura en forma de ranura está hecha en el interior de un contenedor con una parte hueca, un elemento térmicamente sensible tal como una termorresistencia está dispuesto en el interior de la parte hueca, los cables del elemento térmicamente sensible se montan hacia el exterior a través de un agujero pasante hecho en una placa metálica, los cables están fijados a la placa metálica, la abertura en forma de ranura se bloquea por la adhesión de escarcha. El interior del contenedor se desconecta de la atmósfera exterior, la temperatura en el interior del contenedor disminuye rápidamente, la cantidad de adhesión de escarcha puede detectarse detectando la diferencia de temperatura entre el estado sin escarcha y el estado de adhesión de escarcha. También se disponen dos contenedores. Los respectivos elementos térmicamente sensibles están dispuestos en cada uno de los dos contenedores, uno de los cuales dispone de aberturas, el otro de los cuales dispone de un elemento térmicamente sensible para compensación de temperatura, de tal modo que el elemento térmicamente sensible se fija herméticamente. Por tanto, es posible elevar la precisión de detección de la adhesión de escarcha.
