Abstract
Il presente trovato ha come oggetto pressostato, con microinterruttore di sicurezza a riarmo manuale, caratterizzato dal fatto di comprendere un corpo inferiore, presentante al suo interno una camera, in comunicazione con il fluido da controllare, ed associato ad una calotta superiore, che supporta un microinterruttore di lavoro.La predetta camera è chiusa da una membrana, preferibilmente in silicone, munita di OR ed accoppiata ad una membrana di acciaio, con punteria, di trasmissione del movimento, direttamente ricavata su tale membrana ed agente su un piattello, che è contrastato da una prima molla di reazione ed agisce su un pulsante del microinterruttore di lavoro.E', inoltre, previsto un microinterruttore di sicurezza, con riarmo manuale, atto ad interagire con un pernetto, che si sviluppa dal piattello.
