Abstract

Questo sensore di densità per fluidi in contenitori ermetici ed a volume costante ha la particolarità di avere una struttura fissata al contenitore ermetico associata a micro - interruttori con loro tastatori posizionati a vari livelli rispetto ad un piano di riferimento tratto dalla superficie del contenitore su cui è fissata la struttura del sensore, detti tastatori essendo impegnabili su dei piccoli piani disposti circonferenzialmente su di un piattello interposto tra due camere a volume variabile per loro preferenziale allungamento riempite di gas uguali e sostanzialmente alla stessa pressione, una di tali camere essendo ermeticamente chiusa e fissata con un suo piano di estremità alla struttura, e l'altra di tali camere essendo in comunicazione con l'interno del contenitore ermetico da monitorare, detto contenitore essendo indicativamente costituito da interruttori elettrici ad assenza di arco.This density sensor for fluids in hermetic and constant volume containers has the particularity of having a structure fixed to the hermetic container associated with micro - switches with their feelers positioned at various levels with respect to a reference plane taken from the surface of the container on which it is fixed the sensor structure, said feelers being engageable on small planes arranged circumferentially on a plate interposed between two chambers with variable volume for their preferential elongation filled with equal gases and substantially at the same pressure, one of these chambers being hermetically closed and fixed with one of its planes at the end of the structure, and the other of these chambers being in communication with the interior of the hermetic container to be monitored, said container being indicatively constituted by arcless electric switches.
