Abstract
Inventia se fata se refera la o sonda capacitiva de nivel, cu o carcasa de racordare si cu un electrod care iese în afara carcasei de racordare cu partea sa de palpare, aceasta parte de palpare fiind acoperita cu un învelis izolant. Inventia se refera la sonda capacitiva de nivel, cu un electrod care este acoperit pe partea sa de palpator cu un învelis izolant. Spatiul interior al învelisului izolant cominica cu atmosfera printr-un canal de evacuare. Di recipientul de masurare, ca urmare a permeabilitatii la abur a învelisului izolant, moleculele de apa care difuzeaza în spatiul interior al învelisului izolant por iesi astfel spre extrior, în atmosfera. La o reducere brusca a presiunii în recipientul de masurare, se evita atunci o crestere a presiunii în învelisul izolant si prin aceasta se evita o plesnire a acestuia.
