Abstract

Patente de Invenção: <B>"PROCESSO E DISPOSITIVO PARA AVERIGUAR O NìVEL DE ENCHIMENTO DE MATERIAL DE ENCHIMENTO EM UM RECIPIENTE"<D>. Para a averiguação do nível de enchimento em um recipiente (20), radiação eletromagnética partindo do recipiente é examinada. A radiação eletromagnética possui um comprimento de ondas na faixa infravermelha de 1 Ám até 1 mm. A parte superior do recipiente não contendo material de enchimento possui no caso uma outra temperatura do que a parte inferior do recipiente contendo material de enchimento. A diferença de temperatura é obtido pelo fato de que o recipiente depois do enchimento é aquecido ou esfriado pelo lado externo.Invention Patent: <B> "PROCESS AND DEVICE FOR DETERMINING THE FILLING LEVEL OF FILLING MATERIAL IN A CONTAINER" <D>. To check the filling level in a container (20), electromagnetic radiation from the container is examined. Electromagnetic radiation has a wavelength in the infrared range of 1 μm to 1 mm. The upper part of the container containing no filling material in this case has a different temperature than the lower part of the container containing filling material. The temperature difference is obtained by the fact that the container after filling is heated or cooled from the outside.
