Abstract
Il presente trovato ha come oggetto un pressostato a sfioro, con microinterruttore, caratterizzato dal fatto di comprendere un corpo inferiore, presentante una camera, in comunicazione con il fluido da controllare, ed associato, con l'interposizione di un anello portacontatti lamellari, ad una calotta superiore. La predetta camera è racchiusa da una membrana, munita di OR ed accoppiata ad una membrana di acciaio, con punteria di trasmissione del movimento direttamente ricavata sulla membrana stessa ed agente su un piattello, contrastato da una prima molla di reazione ed atto ad interagire su almeno un contatto lamellare, supportato dall'anello portacontatti.E' inoltre, previsto un microinterruttore di sicurezza, a riarmo manuale, atto ad interagire con un perno, che si sviluppa dal piattello.
