Abstract

"DISPOSITIVO DE SENSOR CAPACITIVO". Um dispositivo de sensor capacitivo para medir propriedades de um meio a ser medido quando este meio circunda e flui além do sensor. O sensor tem um alojamento de metal, uma abertura no alojamento transversal ao fluxo do dito meio a ser medido, que é adaptada para alojar pelo menos um eletrodo capacitivo, e onde os eletrodos do sensor são isolados eletricamente do dito meio a ser medido por meio de um material cerâmico de vidro que é arranjado para ser nivelado com a superfície externa do sensor.
