Abstract

Un sensor capacitivo incluye un radiador metálico colocado en una terminal de extremo de un ensamblaje de sensor. Un electrodo coaxial se interconecta eléctricamente al radiador metálico. El electrodo coaxial tiene un conductor central, un dieléctrico alrededor del conductor central y un conductor exterior, el conductor central que está en continuidad eléctrica con el radiador metálico. Un aislante configurado para ajustarse adyacente al radiador metálico se configura para aislar eléctricamente y térmicamente el radiador metálico de propiedades eléctricas y térmicas seleccionadas en un ambiente donde se coloca la sonda de sensor capacitivo. Un conector se coloca distal del radiador metálico en el electrodo coaxial, una porción del conector que está en continuidad eléctrica con el radiador metálico.
