Abstract

Misuratore ed indicatore di pressione, in cui un tubo di Bourdon ed un interruttore elettrico sono contenuti, chiusi ermeticamente, all'interno di un compartimento riempito di liquido, ed un passaggio del liquido viene fornito tra il tubo di Bourdon ed un accessorio esterno. I conduttori elettrici dell'interruttore possono essere collegati al di fuori del compartimento, ed il tubo di Bourdon è collegato meccanicamente ad un indicatore di pressione, per fornire una lettura analogica della pressione effettiva all'interno del tubo di Bourdon, ed il tubo di Bourdon è collegato meccanicamente al pressostato in modo da fornire un azionamento dell'interruttore, ogni volta che la pressione, all'interno del tubo di Bourdon, raggiunge un livello predeterminato.(FIG. 1).
